Battery Charging; Battery Precautions - NEC VERSA 2600 Service Manual

Battery Charging

The time to completely recharge your main battery is approximately 3 hours whether the
system is powered on or powered off as follows:
For maximum battery performance, fully discharge the battery before recharging it. To do
so, unplug the AC adapter, turn off power management features (through Setup and Win-
dows), and turn on the system. (Do not leave any applications running.) Once the battery is
fully discharged, plug in the AC adapter and recharge the battery.
The warning beep that sounds when battery power becomes critically low is always a true
indicator that battery power is low. Be sure to save your data when you hear the beep and
take proper steps to provide power to your system.
