I have a CR2032 mercury battery, and when measured with a digital VOM, it starts around 3.5v and climbs slowly to a little over 6v .
What does that mean?
It's a cheap meter but it's worked fine for years, especially for DCV.

I don't think so but I'll go find another meter.
micky was thinking very hard :
Bad battery? Sometimes a car storage battery won't turn an engine over, but using the headlights for a while heats the battery and it works better at the new temperature. Maybe this is a miniature form of that phenomenon.
Well, I measured it again with the same meter, and this time it was
2.65v and steady. . I figured the battery was bad, but I still don't know what happened the first time (The first two times actually, within a minute of ieach other showed it climbing.).Join the Discussion
