Leaky Batteries

[prpr]

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.

I came across a radio today, I would guess hasn't been touched in at least 15 years. I opened the battery comparment and found the following:



Two batteries branded Panasonic are badly corroded. The Titens look mint (but only register half a volt).

What does that date code say? Looks like it might be 04 2016 from here.
Got the vinegar ready for the radio?

Yes, 2016 for the Panasonics and (what looks like) 2007 on the Titens (stamped into the metal).

I'm sure the 2016 must be a BBE, I have no idea whether the 2007 is a manufacturing date or a BBE date.
