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

T esting a battery while its temperature remains high could possibly cause inaccurate measurements, therefore we strongly recommend:

· W aiting 30 minutes before testing a battery that has just been fully charged.

· W aiting 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.

Battery alarm

The battery alarm is activated by a program and will sound when the battery power is low.

Note: If a fully discharged battery has been charged for less than 3 minutes, this program will not be activated.

This happens when these 3 steps occur:

1. The computer is being used and the low battery alarm sounds.

2. The AC adapter is connected to charge the battery while the computer continues to be used.

3. The adapter is unplugged within the first 3 minutes of charging.

After this sequence of steps, the computer will eventually shutdown without the low battery alarm sounding and you will lose any work you have entered and not saved. Therefore you should make sure that the AC adapter is firmly plugged into the computer when charging the battery.
