backup battery is a coin-shaped battery, the same
type used in wrist watches and automotive
remote controls. The
exact battery type is the CR2032.
the backup battery is very easy. A
small port on the back of the Axim X5 gives you
access to the battery slot. Simply remove
this port, remove the existing battery, and replace
warnings about the backup
power levels continue even after you've replaced
the battery, make sure that you've updated your Axim
to the latest ROM version; some early ROM versions
for the Axim X5 reported inaccurate backup battery
level warnings. Visit Dell's Support
