Maximize your Laptop Batteries

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

1. Breaking In New Laptop Batteries - new laptop 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 capacity.

2. Preventing the Memory Effect - Keep your laptop batteries 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.

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

4. Exercise Your Battery - Do not leave your laptop battery dormant for long periods of time. We recommend using your laptop 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 described above.

5. Laptop Battery Storage - If you don't plan on using your laptop 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.

6. 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 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.

Battery can not be charged up fully

Laptop Batteries use instructions.

Did you recently purchase a new laptop battery for your laptop, but unfortunately, this battey could not be charged up fully in your laptop. if so there are some instructions for you to solve your problem.


1. Your new laptop battery appeared to 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.

2. When charging your 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.

3. 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 user's manual.

4. If your 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 ADVENT laptop battery to become warm during charging and discharging.
5. A charged the laptop batteries will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.
