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 prevent capacity loss
and to avoid deterioration of battery performance. Storage in a 100% charged
condition can cause increased deterioration of discharge capacity—even after
recharging—compared to storage in a 20-50% charged condition.
