Let me first state that I am electrically challenged.
I have installed a Benchmark Design Smart Isolator hooked up to two new deep cycle Sears Diehard Platinum P-1 Group 34 AGM Batteries in a 2010 Jeep Rubicon to power a winch and a 12 volt National Luna Weekender 52L refrigerator.
I have checked these batteries several times while day time driving for over 1600 miles this last week . I noticed that the voltage in each battery was never higher than 12.75. I was thinking that the voltage should be above 13.5 when they are fully charged.
I did no winching while on the trip.
The refrigerator was hooked up. It supposedly is a power miser as it only consumes 0.83 amp-hours over 2 hours when tested recently.
I am interested in keeping my beverages cold for as long as possible while camping over several days.
My question is why the voltage in the batteries is not higher after having been driven for that long of a time?
