The temperature makes the difference. Warm Lead-acid batteries have
lower voltage than cold batteries.

Hi,
My 48 volt utility vehicle has 6 8V Crown brand deep cycle batteries
CR-190, 190 ah at 20 hour rate. The vehicle is in regular use, no
deep discharges, and recharged by a three stage DeltaVolt charger.
I have been noticing that after disconnecting the charger and
letting the batteries rest 12 hours that 5 out of 6 batteries were
8.510 to 8.577. The other battery was consistently around 8.414
volts. I tried an equalization charge of 7.5 amps constant current.
I ran the equalization charge for 8 hours. The battery got warm but
did not use much water. After 12 hours off charge, the voltage read 8.3.
Did I damage the battery? Did I quit too early? Any suggestions?
Thanks
Cliff
