The Expert Performance E•P
®
Charging System enables
your phone’s built-in charger to communicate with installed
batteries and tailor its charging cycle to optimize
performance. If you see
Invalid Battery
when you power
up the phone, the built-in charger is not able to
communicate with the battery and cannot charge it. There
are several possible reasons for this message. The most
likely one is that the battery is not a Motorola original, and it
does not have the appropriate E•P
®
technology.
We recommend that you use only Motorola original
batteries and accessories and that you store your batteries
in their protective covers when not in use.
