To get the most from your battery
The following are some further suggestions for the best management of your OmniBook
batteries.
Do not leave batteries unused for long periods of time. If you have more than one,
rotate them.
If you normally use ac power, make a practice of at least once a week using the
battery as your power source.
Unplug the ac adapter when the computer is not in use.
To preserve the life of your battery, be sure to charge the battery regularly.
For long-term storage, the battery must be charged at 20-50% to save capacity loss by
self-discharge and to avoid deterioration of battery performance. Storage in a 100%
charged condition can cause higher self-discharge and deterioration of discharge
capacity—even after recharging—compared to storage in a 20-50% charged
condition.
