My Poly800 has no internalbattery, and used the batteries for patch storage.  I think there issome variation in the Mark 1 models?

They last for ever - the danger is they go old and leaky so you need tobe strict and set a date to replace them.  I wired the batterycompartment up instead to a PP3 connector (same 9v as the original 6 by1.5V cells)  which I found easier to handle.

Sorry, I assumed that the Poly 800 works in a similar manner as the
casio cz-1, in that the batteries in the battery compartment are used
to keep the patch memory, but Gordon's reply suggests that is not the
case. The Poly 800 already has a cr2032 so that's what is keeping
the patch memory, and it can last up to 10 years. Those bigger
batteries in some synths are rechargable ni-cads that get recharged
when the synth is plugged into the wall. They are not suitable for
the Poly 800 without modification to charge the battery. In any
case, there is no need to replace the cr2032 in the Poly 800 if patch
storage works. Replacing it will wipe the current patch memory
(though as Atom Smasher points out, if you use the Hawk kit you won't
need the battery at all anymore).
