Battery Information
Proper care will improve the performance and extend the life and cycle life of your battery. Please
follow these simple guidelines to get the best use out of your battery.
Power loss
When not in use, a battery will gradually lose its power, this is normal. The rate of power loss
depends on the battery type and is approximately:
2% / Day
for a Ni-MH Battery
0.2% / Day
for a Li-Ion Battery
Battery storage
Outside the computer
If you are going to store a battery outside your computer for an extended period you must:
·
Charge the battery to at least 40% capacity prior to storage.
·
Follow steps 1 through 3 approximately every 30 days:
1. Completely recharge the battery.
2. Use the battery until it is fully discharged
3. Recharge the battery to at least 40% capacity.
Inside the computer
If a fully charged battery is stored inside the computer and the battery is not used for more
than 30 days, you must follow these steps:
1.
Completely recharge the battery.
2.
Use the battery until it is fully discharged
3.
Recharge the battery to 100% capacity.
(In this case it doesn’t matter whether or not the computer is being used)
Note: An empty battery will become damaged if stored too long and by following these
steps the battery cycle life and the battery life will increase.
Battery Testing
Testing a battery while its temperature remains high could possibly cause inaccurate
measurements, therefore we strongly recommend:
·
Waiting 30 minutes before testing a battery that has just been fully charged.
·
Waiting at least 30 minutes before recharging a fully discharged battery.
Note: All battery testing should be done on a fully charged or fully discharged battery.
