Two of the SRAM chips shown in your photo are not LP types.
Those may have standby current high enough to run your batteries down over time.
Probably all of them should be LP ones. Maybe just remove the two that
are not until you can get replacements?

At least check the data sheet for each manufacturer and see what the
standby current is for the non-LP ones.
