Appendix B. Battery Information
Please follow these simple guidelines to get the best use out of your battery.
New Battery:
Always use a new battery before recharging it.
Battery Life:
Battery life may be shortened through improper maintenance. To optimize the life
and improve the performance of your battery, fully discharge and recharge the
battery at least once every 30 days.
Battery Gauge:
The battery has an internal gauge which measures the battery life. The gauge
relies on a battery’s "memory" to determine the level it must stop charging or
discharging the battery. This "memory" will become distorted if you partially
charge or partially discharge the battery too often.
To increase the accuracy of the gauge, you must fully discharge and then fully
recharge the battery at least once every 30 days or after about 20 partial dis-
charges.
How do I completely discharge the battery ?
Use the computer with battery power until it shuts down due to a low battery. Don’t
turn off the computer by yourself even when you see a message or hear beeps
that indicate the battery is critically low, just let the computer use up all of the
battery power and shut down on its own.
How do I fully charge the battery ?
When charging the battery, don’t stop until the battery LED indicator light is
green.
