I purchased a Sterling Power 20A charger from Maine Sail.
When I charge my 12v bank (brand new 2 x Interstate CG2) during this winter, it's putting in 15volts.... sometimes up to 15.3volts.
I'm guessing this is temperature adjusted because I connected the temp sensor to the batteries ?
Is this high voltage charging hurting my new battery bank?
Note: I have only had to charge 3 times at this 15.3voltage - a top up to full at the beginning of Winter. The bank sat at 12.73 for months, but it was at 12.70 yesterday when I visited the boat, and so it gave it a little top up and it occurred to me that 15.3volts is not good.
Thanks
