The Basics
Leaving Batteries in the Charger
Lithium Ion batteries are different from other batteries in
that you can leave them in the charger. Nickel Metal Hydride
batteries should not be left in the charger for more than 24
hours.
Expert Performance (E•P™) Charging System
Your Motorola cellular phone implements the Motorola
Expert Performance (E•P™) charging system. This system
allows the charger that is built into the phone to
communicate with the battery. Based on this
communication, the charger can tailor the charging cycle to
optimize performance. If your charging system is not
communicating with the battery, your phone will beep and
display an
Invalid Battery
message each time you
power up the phone or replace the battery. Your phone is
alerting you that you do not have charging capabilities with
this battery.
There are several reasons why your battery might not be
communicating. The most likely reason is that the battery
you purchased is not a Motorola original battery and it does
not have the appropriate communication technology built
into it. All Motorola batteries are built with the appropriate
communication technology. We recommend that you use
Motorola original batteries and accessories and that you store
your batteries in the protective battery cover that comes with
the phone.
