Extending Battery Life
A battery is an expendable part and may need replacing
during the life of the terminal.To ensure maximum service life
of your handset, always replace the battery with a genuine
Motorola replacement.
In order to ensure maximum life from your battery, do not
place the handset and/or battery in the charger, unless you
really want to charge the battery.
Battery Charging Temperature
Your charger will only charge your battery when it is at
temperature range of 1 °C to 37°C.
This is due to the fact that the internal battery cell can be
charged in the temperature range of 0 °C to 45 °C.
As the temperature gets colder (close to 0 °C) less capacity
is stored in the battery.
If, during charging, the temperature is out of range, the
battery might not be fully charged since the charging is
temporarily stopped until the temperature becomes suitable.
The range of battery operation is from 0 °C to +45 °C in
charger mode and from -10 °C to +60 °C in discharge
(application) mode.
First Time Battery Charging
Always charge your new battery/(whichever type) overnight
(14-16 hours) before using it.This is referred to as Initialising
and will ensure maximum battery start capacity.
Battery Charging Rules
Generally, to reduce the number of charge cycles as much
as you can wait for Low Battery message to charge as this
will ensure maximum battery life.
Do not use your charger as a terminal stand or leave your
terminal and fully charged battery connected to the charger
whilst not charging. Continuous charging will shorten the
battery life.
