Leaky Batteries

The stars of the show appear to be a pair of OEM AAAs marked "HW hi-watt battery heavy duty" with no indication of chemistry (but most likely alkaline), which both still read 1.5V+ on my tester. They make it to my stock.

Have you tried taking any current from them and measuring the voltage? Off-load measurements are not terribly useful for aged batteries.

I have to confess I fell into that trap recently when I tried to use a fairly old battery which gave a satisfactory voltage reading but wouldn't bring the device to life; took me a few minutes before I tried a known good battery.

These were on-load measurements using a proper battery tester, but I admit I don't know what the load current is. The second Kodak didn't register at all on-load.
