Laptop batteries and batteries in general are paramount to our survival in this wireless mobile world. Without power for our devices, we will be standing still or looking for the nearest AC power outlet. Until a limitless power cell or Toshiba Laptop Battery
battery is invented, we are stuck with the ones that we have now and the only way to prolong the battery life is by taking very good care of the battery. Typical battery life is about 1.5 ?3 years which is about 500 ?800 charge/discharge cycles.


Laptop Battery Chemistries
Batteries contain chemicals which react together and produce electricity. The three main types of battery chemistries are Lithium Ion, Nickel Cadmium and Nickel Metalhydride. One of the latest types is Lithium Polymer Ion. Due to health and safety and inefficiencies Nickel Cadmium batteries and Nickel Metalhydride batteries are being phased out. For more technical information check the Battery Types and Chemistries pag eToshiba PA3506U-1BRS Battery on BatFaq website.

Memory Effect
Ni-Cd batteries orget?their full capacity. This is called the memory effect. When a battery is put on charge whilst it is only partially discharged, it charges partially, not to its full capacity. To avoid this, use the device without AC power until battery is fully discharged and then recharge the battery completely. This should be carried out once a month, to obtain optimum results from the battery.

If your battery is not lasting as long as it should, even the batteries designed into laptop computers can be easily replaced by the user.

Laptop Battery Maintenance
How to charge your new replacement laptop battery?
Your new laptop battery comes in Toshiba Satellite A10 Series Battery a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.

When charging the laptop battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.

It is important to condition (fully discharge and then fully charge) the laptop battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-ion batteries, which do not require conditioning). To discharge, simply run your device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your Toshiba Satellite A100 Battery user's manual.

If the laptop battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.

It is normal for a laptop battery to become warm during charging and discharging.

A charged laptop battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.

The milliamp-hour (mAH) rating of the laptop battery dot org batteries will often be higher than the one on your original battery. A higher mAH rating is indicative of a longer lasting (higher capacity) battery and will not cause any incompatibilities. An laptop battery dot org battery will, in most cases, outperform the original by 30% to 50%.

Actual battery run-time depends upon the power demands made by the equipment. In the case of notebook Toshiba Satellite A70 Battery, computers, the use of the monitor, the hard drive and other peripherals results in an additional drain upon the battery, effectively reducing the battery's run-time. The total run-time of the battery is also heavily dependent upon the design of the equipment. To ensure maximum performance of the battery, optimize your computer's power management features. Refer to your computer manual for further instructions.

How Can I Maximize My Laptop Battery Performance?

There are several steps you can take to insure that you get maximum performance from your laptop battery:

Breaking In New Batteries - new batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated Toshiba Satellite A75 Battery capacity.

Preventing the Memory Effect - Keep your battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-ion batteries which do not suffer from the memory effect.

Keep Your Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and your portable device.

Exercise Your Battery - Do not leave your battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure Toshiba Tecra 8000 Battery described above.

Battery Storage - If you don't plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, NiMH and Li-ion batteries will self-discharge during storage; remember to break them in before use. Sealed Lead Acid (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.

For Notebook Users - To get maximum performance from your battery, fully optimize the notebook's power management features prior to use. Power management is a trade off: better power conservation in exchange for lesser computer performance. The power management system conserves battery power by Toshiba Tecra 8100 Battery setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it's not in use and causing the machine to go into sleep mode when inactive. Your notebook user's guide will provide information relating to specific power management features.
