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 inuALid 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.
