1.4 Using the Battery Packs
This section describes the charging the battery pack.
Charging the Battery Pack
Before you use your Handheld tablet PC, you need to charge the battery pack. The battery pack begins to charge as soon as the
Handheld tablet PC is connected to the external power source. Please fully charge the batteries before using them for the first time. The
new battery packs must be fully charged before the tablet PC is disconnected from the external power source. The battery pack is fully
charged when the battery light indicator turns OFF. It takes about a couple of hours to fully charge the battery when the Handheld tablet
PC is turned OFF.
Battery Care
The Handheld tablet battery pack, like all rechargeable batteries, has a limit on the number of times it can be fully recharged. Fully
draining and charging the battery once a day will make the batteries last over a year, but rechargeable time limits are based on your
environmental temperature, humidity, and how your tablet PC is used. The ideal environment temperature range is between 10°C and
29°C (50°F and 85°F).
Battery Power System
This tablet PC is designed to work with two removable battery packs placed inside the battery pack compartment. The fully charged
battery packs will provide several hours of battery life, which can further be extended by using power management features through the
BIOS setup. The system includes a power management software which allows the battery to accurately report the amount of charge
percentage left in the battery.
Charging the Battery Pack
You can charge the battery pack by using the power adapter. When the power adapter is plugged in, the inserted battery packs
automatically recharges whether your tablet PC is in the ON or OFF mode. It takes about a couple of hours for the battery to be fully
charged when the power is OFF but takes twice as long when the tablet PC is in use. When the red charger LED indicator indicates
orange, charging is required. The battery is charging when the red LED is solid. When the LED is turned OFF, the battery pack is fully
charged.
