Maximizing the Energy Stored
To maximize the energy stored in the battery pack, follow these guidelines:
•
Condition a Battery Pack at least every 30 days to improve overall battery performance.
•
Keep a battery pack in the Notebook when using it with AC power to supply the battery pack
with a constant trickle charge.
•
Store the battery pack in a cool, dry place when not in use.

CAUTION: To avoid loss of data, make sure that all information is saved before
completely discharging a battery pack.
To condition a battery pack, complete the following steps:
1. Plug in the AC adapter and allow the battery to charge until the fast charge arrow on the
status display disappears. The battery gauge may read 100% for a period of time before the
arrow disappears.
Note: Do not unplug the AC adapter until the arrow disappears.
2. Unplug the AC adapter and allow the battery to drain until the Notebook enters Hibernation
mode. The Notebook can be used normally during this process.
Note: If the AC adapter is connected while the battery is draining, the process must be
repeated, beginning with Step 1.
The battery is now reconditioned. Plug in the AC adapter and begin using the Notebook.
The table below shows typical battery charging times for each model.
