I might tuck a CR123 in a holder inside the case somewhere, with a blocking diode. I think I already have some suitable holders left over from when I did the same thing to repair a bad NVRAM battery in an old HP digital oscilloscope. It was hard to get to the original cell in that one (an AA sized one with wire leads, as I recall), so I replaced it with a CR123 mounted remotely inside the back panel so that the next replacement will be easier.
