HDR CX-240 losing its settings after battery swap

[CX240-USER]

Hi folks - I've got 20 of these little camcorders and one of them has decided to 'go rogue' on me.

If I take out the battery, then reinsert it, the camera loses its settings - date/time/quality etc.

I'm guessing the 240 uses an internal, backup battery to hold these settings, and this one has expired.

Can they be replaced at home? What's the procedure?

Thanks 🙂

There is an internal Backup Battery, but for its replacement I am afraid you will have to contact an Authorized Service Center.

Thanks for taking the time to reply. All the cameras are well out of warranty and I'm handy with a screwdriver and soldering iron. Or is the battery some Sony (impossible to obtain?) one, I wonder.
