I have two car type batteries that I have in my basement. One is to
start my generator and the other is a spare. I charge them once a week
at 1.5A for three hours. I check the voltage before charging. One of
them usually reads 12.60 volts and the other 12.76 volts. I checked the
acid level on the 12.76 volt one and it is OK. Why would it read so
high?

You are concerned about a .16 v difference between the two?
