Battery voltage increases when voltmeter connected

When I connect a AA rechargeable battery directly to a voltmeter, voltage increases slowly, regardless of the way I connect it. I can't figure out why.

Increases from what to what? And what do you mean by "regardless of the way I connect it"? There aren't that many ways to connect a DVM to a battery... :smile:

This happened to me last year when I was measuring the voltage on a car battery.
It turned out the battery in my voltmeter was going dead.
Replacing the battery in the voltmeter made the problem go away.

Sometimes the heat from your hand is enough to boost the chemical reaction in the battery increasing the voltage.

Correctly anyway. I wondered the same thing.
