If Chris' unit is a true 2465 (not a 2465A or B) it has no battery.
The 2465 uses an EEPROM for storage.

I tried the scope again a little later on and the display came back, but tried it again today and it worked for a few minutes then suddenly jumped off to the right again.
I do have the service manual for it, but before I start digging in, are these the typical symptoms of U800 failure?
Chris, I don't know how typical, but this is exactly what mine did
having I bought it "working" at our local swap meet. I would not say
impending, I think it has happened. Eventually I replaced the U800 with
one found in a "parts unit" bought on eBay for $125 and all has been
fine since. Obviously this required a bit of risk taking. Sources for
the horizontal hybrid are few and far between, and I didn't like the
alternatives. My "parts unit" has provided a few other things that have
come in handy, a spare tube, fan and HV module among others.
In the end, I did a complete overhaul, loads of new caps, new battery,
and a full calibration, so I'm hoping it will see me out.
Yours at least will probably also need a new memory battery if you've
had it that long.
