Six steps make you use lithium battery safely and long

The world’s largest computer manufacturer Dell Inc. announced that they will recall millions of laptop batteries. Because these batteries can catch fire. The batteries were produced by Japan’s Sony Inc that famouse of its lithium battery technology. A few days ago, Sony’s own laptop batteries are also burned in the United States.

Lithium-ion laptop batteries now are becoming the synonym of insecurity. They has even been called “technological terrorism” : technical imperfections caused by security threats by some American columnists.

However, despite this, life had to continue. We currently can not leave them because lithium-ion batteries is the most important part of the thin and light portable electronic products.

So, scientists are rearching alternative fuel-cell to replace lithium-ion Inspiron 6000 Battery . At the same time for ordinary consumers, we must know how to use lithium-ion batteries safely, that is probably more practical.

First of all, we can not ignore the lithium battery. We should know that rechargeable Dell inspiron 1545 battery is “a source of strength” of portable electronic devices that you can see everywhere . From notebook to cell phones, from cell phones to MP3, from digital cameras to electric bicycles, from the CD machine to digital camcorder. However, we often take a little attention to them, unless the phone is power off when a important call coming , or we prepare the luggage for a trip.

Recent events made us realize that the battery is very important to our daily life, so we have to understand them.

Lithium-ion battery (Li-ion) rechargeable Dell Latitude D520 Battery, typically used in notebook computers, mobile phones and iPod. There is also a rechargeable nickel-metal hydride battery (NiMH). This battery is currently mainly used in cordless phones, cheap digital camera and a small part of the notebook computer.

Some simple note will let you lithium-ion battery using relatively more secure and more longevity.

First, do not contact the dell vostro 1400 battery positive and negative part with metal objects. Place the lithium battery stay away from metal objects and the high temperature areas in order to avoid the battery short-circuit.

Second, you’d better charge lithium-ion dell vostro 1000 battery with original charger, or it will damage the battery and shorten their life, serious may even cause an explosion.

Third, frequently use is a good way for lithium battery live longer. But let laptop battery always in the charge state is not OK.

Fourth, the lithium-ion battery has no memory effect. Do not need to fully charged the Sony VGP-BPS8 VGP-BPS9/S battery when charging, so the battery is used not to in 0 ‰. Especilly for the camera lithium-ion battery, once the power state in zero, then the battery protection circuit starts. Some manufacturers battery (as Sony) cut off the main circuit inside, then the battery locked.

Fifth, when a battery not in use for long time, the Sony VGP-BPS8A VGP-BPS9/Blaptop battery should be stored at low temperature, dry environment, away from heat, do not placed in direct sunlight areas. Generally considered, it should be charging to about 40% of the electricity and store at 10 to 30 degrees Celsius temperatures. Do not forget charge the battery every six months or so.

Sixth, when the laptop in hibernate mode but the VGP-BPS9 Sony VGP-BPS9A/B battery is in working state, so you had better turn off the computer when not using. In addition, if your laptop has Bluetooth, or wireless capabilities, it is best to turn off when not in use these features, as they search for available networks is also to be power-hungry.

Hopes that help you.

Customer review :

I would not get this product. I would not buy a laptop from Dell again. Laptop Battery barely lasted a year and was told I had to buy another one that this was the normal life of battery. Bad Product!

This Dell Inspiron E1505 Battery just died on me. it wont charge more than 37% and now i have to buy another one…

The replacement products in Amazon review :

was skeptical buying this battery for my Dell Inspiron 1420, being it so cheap. Any computer store around where I live the batteries were over $150 for standard capacity and even more expensive [...]. This is a great buy.

The only downside is that it is a heavy Dell Inspiron 1420 Battery and was not fully charged when I first put it in.

Otherwise, it works well and gives me 4 hours to float around on battery.  

Since receiving (Amsahr-quick delivery) and using this Dell Inspiron 1720 Battery and charging and discharging it approximately 6 times, it has performed excellently and with high performance. It also fits perfectly like the original, and was priced very reasonable.

As we all know the laptop battery is important to our laptop. Some times when your laptop battery run out in the open air, what should you do? Go home to get a replacement. No no you need not. Take out your torch battery to power your laptop.

In fact, laptop batteries can be replaced with any other kind of offers it is right or sufficient voltage. Here I am with two 6V LIFEBOOK T4010 battery  manipulated up to twice the voltage to the power of a Compaq Armada 110th

Step 1 Remove power

All you need for your old Fujitsu Lifebook T4020 battery to disassemble the battery, I was very stubborn and I have it only with a considerable distance to cosmetic damage, please try to set it apart from the contacts when the battery is connected to the laptop, I have but not real pictures of this step, as I have about 1 month ago, and I just un-earthed casing of the battery when you’ve received a little wrung from the battery housing to things either easier or a little more difficult was the Battery Compaq merged, so I was almost broken just plastic!

After the Lifebook T4220 battery  unless you have some 9-cell battery, depending on the type of laptop was to find battery. You need to pull out all those bulky batteries, which certainly does not lead to rip the wire to the batteries from the board (Figure 2)

Step 2 Source improvise and power

To some batteries in the laptop, I have two  Fujitsu Lifebook T4310 battery  in my 5 million candle power torch, to assess each 6V to 12V to get as they were manipulated together for combined power, power, I do not know how long they modified battery is fully charged, but I guess at least 30 minutes. 100% CPU

If you have two batteries you need to red) to positive (a battery to the negative (black connect) from the other Fujitsu Lifebook T4410 battery .

Step 3 Connect power.

Now that they’ve been getting your Fujitsu Lifebook T5010 battery, the next thing to do is connect them to the leads of the laptop battery board, you have the positive of your new batteries to the positive lead connected to the PCB. I recommend that the cables of a decent length for a simple, but also tinged with red and black wires to the corresponding compounds battery (ie connected to red, red), it makes things easier.

Step 4 Replace remastered Battery

I had a small hole for the wires to pass from the Dell Inspiron 1721 Battery  case, remember this and to do, so that the cables come in a handy place to do this if you do not want to spoil your battery housing provides good.

Step 5 Testing the new power

It must be said that I use to boot to the A / C power connector on the laptop, but after that it worked well without the A / C had power, I do not know if this because the laptop is old and it couldn ‘t was you know the batteries to boot the laptop, but it does recognize the Dell Inspiron 6400 Battery  with the A / C power is connected and switched off the laptop.

Work with : Latitude D820 battery, Latitude D830 battery not competiable with the Latitude D620 Battery

Customer Review:

I have had other laptop batteries lasting well over two years. This one really disappointed me. It looks like in order to cut costs, Dell may have sacrificed quality.

From the looks of it, many people are having the same problem I have with the laptop battery. The battery was giving decent run times until it reached an age of about 20 months. After that, it went to about 10 minutes of run time.

While this is not an absolutely horrible lifetime, I typically have had Dell Latitude D830 Battery last about 3 to 3.5 years before this happens.

The Dell latitude D830 battery replacement reivew in Amazon:

I have a Dell D830 (purchased 1.75 years ago) & a Dell D820 laptop (purchased about 3.5 years ago). The batteries are interchangeable in these 2 and the old D820 battery has begun failing to hold charge so I bought the AGPTEK Super-Capacity Li-Ion battery. The Latitude D820 Battery arrived DOA, no status lights and neither Dell recognized it. I sent it back for $8.70 in postage and the replacement does work and so far is reporting a good charge: 3.5-4 hours in the Dell D830, which is about the same as the 1.5 year old battery reports. The replacement is only a month from manufacture if I read the code AGPTek pasted on it (it has 20090720 embedded in it), and both the dud and the replacement fit well in both my Dells. However with the cost of shipping the dead battery back this battery was not such a bargain.

Purchased the Dell Latitude D820 Battery in Nov 2008 and it worked as advertised for between 6 and 7 months. At that point it quickly lost the ability to hold a charge. It still works in that my laptop can run for about 15 minutes on the battery, however the battery has bottomed out and only accepts ~20% of the capacity it had when new.

My experience with original Dell batteries is that they last about 18 months, however the cost is much higher.

This replacement battery for a Dell Latitude D830 Battery lasted 3 months before the charge wouldn’t last more than an hour. The original battery would run for 3.5-4 hours on a charge, and lasted for over a year. Now at 5 months on this battery, the computer tells me that my battery is “reaching the end of its useful life”.

Where is Laptop using heat come from

We are using the notebook for some time. Weoften found that notebook slowly get hot after using for a while, especially the bottom of laptop. The situation occur frequently in Summer. Where is laptop using heat come from?

When the machine overheating, some harm reasult happend: laptop system halted, restart, and even laptop parts burn (espacilly laptop battery). Which laptop part produce such a large amount of heat? Here I will give us a presentation.

As the desktop CPU’s power consumption and heat is very large. It can not be used in notebook as Dell WW116 , so mobile processors is specifically designed for notebook. Many notebook CPU processor power consumption are over 20W, particularly in the mobile Pentium 4 processor. Though there are a lot of technology tips make notebook average energy consumption low, but the peak is still very high (more than 30W) when using. Many of these energy consumed will come into heat dissipation. Therefore we should always check the clearance of xps m1730 battery CPU fan air vents. Make sure there are no stolen goods block the air vents, that cause the heat can not dissipate. If the notebook CUP silicone hardening, we should replace it in time.

First, the XPS M1530 Battery notebook cooling heat is mainly come from the CPU working heat. But CPU heat is not the all. And the early CPU processor heat is not very large. Just use some simple passive cooling method that can satisfy the cooling needs of the machine. That is the heat sink cooling as we usually known. However, as the continuing escalation of CPU processors, while in the Pentium processor century, the processor’s cooling is the big problem.

Secondly, the graphics card heat is also a large proportion. Early graphics cards heat is not large, but now a lot of high-end machines such as Inspiron E1505 Battery Inspiron E1705 Battery often configure the ATI Mobility Radeon HD4750 or GeForce GT240M such a good graphics card, so the heat also increase a lot.

Finally, there is some other hot parts, such as memory, hard drives, laptop battery, are also a number of laptop heat source.

Dell Lithium-Ion Latitude D630 battery Review

The Latitude D630’s 14.1in. wide-screen display is remarkably bright (223 cd/m2 in our Labs measurement). Its 1,440 by 900 native resolution is as sharp as some desktop replacements. With its standard battery, the Latitude D630 weighs 2.3kg. And the standard battery can last about 2-3 hours. We all know that the batttery is the most important accessories of laptop for mobile using. So I specilly introduce the laptop battery for you.

The Dell latitude D630 battery Tech Specs

• Technology: 6-cell lithium ion
• Capacity : 55Wh
• Voltage: 11.1V
• Weight: 311.50g
• Colar : Dark Grey

The Dell Latitude D630 battery official introduce: Always on the go? No more worries about running out of battery power! You can power your wireless keyboard with this 6-Cell Lithium-Ion Primary Battery from Dell™. With a capacity of up to 56 WHr, the battery lets you work seamlessly when you are on the move for business trips or vacations. This battery provides uninterrupted reliable performance you need to get the most out of your system. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.

The Dell Latitude D630 battery customer review :

The Dell D630 battery that was included in this D630 laptop was unusable within a year of owning this machine. Dell will not replace their own defective part because it has been 1 year and 1 week since the machine was delivered. This laptop has already had the hard drive and the power cord replaced and based on other reviews, there is clearly a problem with the battery. After spending 45 minutes on the phone with technical support and no access to a supervisor, I will not use Dell to replace this battery.

From the looks of it, many people are having the same problem I have with the laptop battery. The Latitude D630 battery was giving decent run times until it reached an age of about 20 months. After that, it went to about 10 minutes of run time.While this is not an absolutely horrible lifetime, I typically have had batteries last about 3 to 3.5 years before this happens.

The Product Dell Latitude D630 battery replacement in Amazon review:

My battery lasts for 2 hours after 2 weeks of use(after following best practices of charging/discharging) which I would consider poor performance even after relatively cheaper price as compared to Dell battery that would last for at least 4.5 hours after 3 months of usage. I had to struggle a lot to fit the battery on my Dell D620. I would think twice about buying cheap as it may also be cheap in performance. I could not locate the contact number for this vendor as they don’t print it on their payment receipts. Why would any vendor not like to give its customers a customer service number to call unless they are expecting return of goods instead of repeat customers

Physically, this item is nearly identical to the Dell branded battery. There are no quality issues at all. It does have the battery meter on the bottom, just like the original one. Since my Dell unit crapped out after 18mo, I can’t do any side by side comparisons, but I think the original unit had a bit more capacity. I recall getting 4 hours on my D620 running Fedora Linux (thought that was for maybe the first couple months). This unit is maybe 3-3.5 but again, I haven’t really done any scientific tests. It could be that I’m just harder on the Latitude D630 battery now than I was then. Either way, it’s a steal at roughly 1/3 the cost of the Dell unit.

Hopes that help you.

The 10 factors that can affect Laptop battery using time

The article first post in http://www.laptops-battery.co.uk/blog/

The process of using notebook computers, some factors that make the battery wear and tear. Even the laptop battery maximum using time less than the standard battery life, it not means the battery have some problem in inherent quality and performance. Notebook battery capacity mainly determine by the size of the marked mAh on battery. The size of the laptop battery MA hours directly related to the using time. Battery using time are also have a great relationship with notebook configurations.

Then we list all the specific factors that can affect the Dell WW116 battery life:

Factor 1: the processor speed - install the the right Intel chipset driver will enable the system to use Intel’s Speedstep technology, that can adjust processor speed in application system to extend the battery life.

Factor 2: Reading CD, DVD, CD-RW and hard drive frequently- the CD-ROM copy of the file directly to your hard drive, watch videos, dials and other operations will affect the Latitude D620 Battery life.

Factor 3: the total number of memory- if the system opens a lot of applications will take up a lot of hard disk space to do file-swapping (virtual memory), resulting in frequent hard disk read and write.So increase more memory will increase the battery using time .

Factor 4: Some applications to run automatically in the background, it will increase the CPU load, resulting in reduced Latitude D520 Battery using time - We usually suggest that turn off some background programs in the daily use, only run the necessary applications.

Factor 5: LCD’s brightness - the lower the brightness the longer battery using time if possible. You can use keyboard function keys to adjust the LCD brightness .

Factor 6: Power Management and Speed Step settings - Set the different power scheme in the power management will affect Inspiron 1720 Battery using time.

Factors 7: Battery life - the average battery life is one year, the gradual reduction of battery usage time is normal as the using. We also think it is the battery aging time.

Factors 8: For the processor and system equipment deeper applications (such as watching DVD movies and 3D games) will make the Inspiron 1721 Battery using time quickly reduce.

Factors 9: Wireless devices and Bluetooth devices will accelerate Dell XPS M1730 Battery consumption; When do not need wireless, you can use the keyboard function keys to turn off the wireless and Bluetooth to save power.

Factors 10: The environmental temperature - too high or too low ambient temperature will affect battery core activity of chemical substances, thus reducing the battery using time and life. The factors is happend obviously in Sony battery as Sony VGP-BPS8 VGP-BPS9.

Overall, the laptop battery using time is not only determined by capacity mAh, the hardware energy-saving technology is also very important.

How to charge your laptop battery properly?

During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.

For early notebook batteries as Dell XPS M1730 Battery (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.

In fact the lithium batteries has a little memory effect. The lithium VGP-BPS9/S battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.

A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had “full” level.

Sometimes WINDOWS show that ThinkPad R40 Battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery

So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the IBM ThinkPad R50 Battery. This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

Q Is it easy to install a battery?
A Yes, very easy. First, make sure all open files are saved. Next, either attach the AC adapter directly to the lap or set the system to “hibernate” mode or shut off. Release the latch on the current battery, and simply install the replacement Dell Latitude D830 Battery.

Q Will Dell laps accept non-Dell batteries?
A Dell has a rigorous qualification process by which all Dell batteries are validated to ensure proper function, performance and safety. Some non-Dell batteries are available in the market with claims of compatibility with Dell systems. Dell cannot verify these claims, nor the safety of using them in a Dell system. Dell strongly encourages our customers to use only Dell lap batteries advertised as appropriate for their lap model. Only Dell lap batteries come with a 1-year warranty, are engineered for optimal safety and performance for Dell systems, and are supported by Dell technical support for the length of the warranty period.

Q What is a modular bay battery?
A In some lap systems Dell offers a Latitude D620 Battery that can be used in the optical drive media bay (DVD/CD drive bay). This enables the use of two batteries, potentially extending the available run time.

Q If I install a modular bay battery, are my primary and modular bay batteries working at the same time to power my lap computer?
A No, the modular bay battery is used first, then the system automatically switches to the primary battery. This is a deliberate design to allow the most amount of run time to remain in the primary Dell KD476 Dell U4873  battery in case the modular bay battery is removed and replaced with an optical drive.

Q For what use is the strip of LED lights on my battery?
A Most Dell batteries have an LED indicator that allows users to see how much run time and how much overall battery life are available at the touch of a button.

To check Sony VGP-BPS8  charge, press the button and the number of lights that appear will tell you charge status. If all lights appear, you have a fully charged battery. Each light that appears accounts for approximately 20% charge.

To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition and approximately more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, approximately less than 60 percent of the charge capacity remains, and you should consider replacing the Inspiron 1100 Battery .

Q What does Dell recommend for battery storage for a long period of time?
A When storing for more than 4 days these guidelines can better preserve the life of your battery:

Do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters and lap security carts plugged into an outlet.
Lap batteries, including those stored in lap systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
Batteries may be stored in the lap or outside of the lap.
Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the laptop battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)

Q Are there restriction with taking lithium-ion batteries on planes?
A Effective January 1, 2008, the Department of Transportation (DOT) through the Pipeline and Hazardous Materials Safety Administration (PHMSA) will no longer allow loose lithium VGP-BPS9/B  batteries in checked baggage. These batteries may continue to be packed in carry-on baggage.

Q How long does a Dell laptop battery last? When should I consider replacing mine?
A All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new Dell Latitude D610 Battery  when the run time does not meet your needs.

Q How should I choose between two batteries with different Watt hours (Whr) available on one system?
A Higher Watt hours (Whr) on the same system under the same operating conditions will generally deliver longer Dell Latitude D620 Battery  run time. For example, if you compare the same system, running the same applications, the 53Whr battery would provide approximately 65% more run time than the 32Whr battery.

Q How long am I able to use my Dell lap on a fully charged Dell U4873 Dell D5318  battery?
A Many factors affect the amount of time that a portable computer battery can deliver power before it must be recharged. These factors include the configuration (processor, memory, etc.), types of applications being run and display brightness.

Dell uses industry standard benchmarks for battery run time claims. For more information on battery run times and benchmarks, the white paper, “Understanding Battery Life in Portable Computers” is available at:

Q How do I charge my Dell GD761 Dell 75uyf battery?
A The battery charges in the lap when the lap is connected to an AC power source via the AC adapter.

Q How long does it take for a Dell lap battery to fully recharge?
A The charge time varies depending on the system. If the system supports ExpressChargeTM , the Dell Inspiron 6000 Battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.

Q What is ExpressChargeTM ?
A For a system advertised as having the ExpressChargeTM feature, the battery typically will have greater than 80% charge after about an hour of charging and fully charge in about 2 hours with the system off.

Q Should I totally discharge, then recharge my Dell lap battery occasionally to make it last longer?
A No, discharging and charging does not increase the life of a Lithium Ion technology Inspiron 630m Battery.

Q Can a Dell lap battery be “overcharged”?
A No, the battery is designed to s using the charger when it reaches full charge.

Q When docked or AC adapter is plugged into a wall outlet, am I using my battery charge?
A No.

Q Does Dell sell external battery chargers for Dell Inspiron 510M battery?
A Dell offers a Datamation battery charger for large institution customers. The charger has 16 charge bays to charge batteries for Latitude D500/D505/D510/D520/D600/D610.

Re-understand notebook lithium battery maintenance

Li-ion batteries in a life cycle in general can be 300 to 500 times charge-discharge. So many people think that, as long as using less battery, so that you can to a certain extent, played a role in extending battery life. But they did ignore the original Dell Inspiron E1705 Battery that the physical nature of the end when the battery off the assembly line, it’s internal life, the clock will then start walking.

So even if you do not set aside the battery, lithium Dell Latitude D510 Battery life was only two to three years you can come to an end of. Battery capacity caused by reasons for the decline was due to oxidation caused by the battery internal resistance increases. When the electrolytic cell resistance reaches a certain point, although this time the battery still be full of electricity, but the battery has been unable to release the stored electricity.

Caused by lithium LIFEBOOK T4010 battery is the speed of this aging temperature and set aside when the charge state of preservation decision. I will give a table to illustrate the different situations of these two factors, the impact on the battery capacity.

Can be seen from the table, high charge state and the high temperature accelerated the decline in Lifebook T4220 battery capacity. Therefore, if possible, as far as possible, after the battery charge to 40% placed in a cool place to save. This allows the preservation of a long period, the battery protection circuit is in its working state. And if the battery is fully charged, will be placed at high temperatures, which will cause great damage to the battery, the table has also been seen, charge 100% in the 60 ° C environmental conservation, 3 months after the battery capacity fell by 40% .

Therefore, how to save the battery solved the issue, but also leads to another focus of everyone has been argued, that is when we use a fixed power supply when there is a need to remove the Apple A1148 battery? Before the resolution of this question let us first analyze the use of fixed power supply when the battery placed in a computer environment in which … … at this time due to charge notebook computers role in protection circuit, so that the battery remained at 100% of full power state, and this When the battery in which the ambient temperature between 25-30 ° C, at least, if the hot weather, this temperature will be higher, then from the table, you should be very natural to come to a conclusion that it is so to do this would actually damage the battery, causing a decline in its capacity.

But despite the use of laptop computers, high-temperature will bring damage to the Apple A1175 battery. But Qudiao battery, use only a fixed supply, there will still some danger that dust and moisture will cause some damage to the battery, while the use of notebook computers in order to avoid a sudden power notebook computers may cause damage, so Manufacturers generally warn users not to remove the battery. Of course, this result will be naturally imagined, your battery as often in such a relatively poor environment, it will not be long over, and then you will need to go to repair center to replace the battery, this way, the benefit of course, is a manufacturer.

Finally we spotlight a lithium battery that is exactly how a reasonable charge and discharge this issue. For the lithium battery is best for partial discharge, rather than fully discharged, and to as much as possible to avoid frequent full discharges. Regular Apple A1185 battery too low discharge of the result can only be scrapped so that the battery in advance, because if the battery into every cell of 2.5 volts below the battery’s internal safety circuitry will be switched on, this time the battery will become some bad spent. Therefore, in order to avoid such situations from occurring, do not save the battery power before its release was erased, but rather a number of electric charge in the store before, and again before the first fully charged.

All in all, in order not to make your premature loss of the role of the battery, then the use of normal, you should try to comply with the following principles:

A. avoid full discharge, and often for lithium batteries. The repeated arbitrarily rechargeable lithium Toshiba PA3331U-1BRS battery damage is very small, almost negligible.
B. will need to keep hold of lithium batteries placed in the shade, remember not to put in the refrigerator. Avoid placing hot car, such as a long time to save the battery charge to 40% in place.
C. most of the time if you are using a fixed power supply, please remove the batteries placed in the shade.
D. no need to purchase spare lithium batteries for storage, so this piece is actually a waste of Toshiba PA3356U-3BRSbattery.

Battery is brought to use, as long as the attention to rational use and preservation methods, there is no need to care for their excessive, making it possible for its owners contribute more to performance is the most important.
