1.2.1 Batteries
Battery types
The iPAD has a main battery and an auxiliary battery.
Main battery:
The main battery is used to back up the contents of memory during
normal operation and in suspend mode.
Auxiliary battery: The auxiliary battery is used to back up the contents of memory if the
main battery loses its charge or the main battery is being replaced.
Guidelines on battery life
1. Main battery
As a guideline, the life of the main battery is either about 500 chargings and dischargings
or two years.
The more a battery is used, the shorter the time it will last. The life of the main battery has
expired if it loses its charge in a very short time after being fully charged. When this
happens, replace the main battery with a new one.
Main battery life may be less than 500 chargings and dischargings or two years depending
on ambient temperature and how the iPAD is used.
2. Auxiliary battery
The auxiliary battery is used temporarily to retain data while the main battery is being
replaced.
The auxiliary battery backs up data in the iPAD's memory during replacement of the main
battery.
To replace the main battery, have ready a fully charged main battery and complete the
procedure within ten minutes.
The auxiliary battery is embedded in the main unit and cannot be replaced.
Message screen when recharging message displayed
When the battery charge falls below a certain level, a message prompting you to recharge
the battery appears.

You can check the status of the battery and the remaining battery charge.
