were the wrong size batteries fitted at a previous date? or did a battery leak in the battery compartment?
it sounds like the metal spring at the bottom of the compartment isn’t making good contact with the battery, so it may be corroded or flattened too much.
You can remove the inner frame on these to inspect and clean the contacts, but it’ll likely be one of those two scenarios.

I hope this helps
