VO meter question
 

I was checking the volts of two batteries in the shop last night with my multimeter. When I checked one it almost instantly showed 5.7v and started to climbing to 5.8V within about 5 seconds where it seemed to stop. When I checked the second battery it instantly showed about 2.7V and slowly started climbing like filling your car with gas at the gas pump, I stood there for at least a minute (slightly longer) as it would climb all the way to 5.85V is where it seemed to stop!!! It would climb at a slow but steady rate for a bit, then it would climb .01 volt every three or four seconds, THEN at a point start climb at a constant steady rate again THEN slow back down and move .01 volts every 3 - 5 seconds and pick back up again. What's up OR WHY? I could go back to the other battery and BAM, 5.73V and climb again to 5.8 within a few seconds!!!

You don't seem to be considering that the meter may be faulty, try another meter.

I bought a bunch of these analog multimeters at a dollar store in Texas about 15 years ago, gave them all away except one. Rock Auto carry’s them and I’m sure eBay has them also. I keep one in my trunk of my ‘41, these analog meters seem to work better on old 6 volt circuits than the new digital ones.

Make sure your battery post are clean. If so, as mentioned above try analog meter.

Acting like the battery in the meter going dead.
