OK if I have to modify the battery compartment for AC connection.

Yes. It can be set to never shut down, and you can supply 5 to 5.2 VDC
to the battery contacts within. There is no external power connector.

Make that a regulated supply, pls. Probably goes without sayin' but
....

I haven't measured it, but I'd guess it could take at least half an
amp at times. I'd allow for an amp. An LM7805 regulator chip would
provide the regulation for under a buck. Email if you want more info.
