I know there is a battery in there but I'm not sure just what it does. One would assume it keeps the time etc. during a battery pull. I've never replaced one, though.

yes,now i'm sure that there is a battery on PCB in 8700 handhold.
and the purpose of this battery is to maintains the RTC(real time clock) on PCB when recharged battery is remove from handhold.
hehe,now I try to replace the small battery by myself.
First of all,I wonder how to replace the battery and where it is.because I can not find it from the 8700 PCB pictures which are posted by other users.

It's a tiny battey and is soldered in. It's not a simple repair, but I'm sure its quite possible.
