Amp/hour test is way off-
I have installed two NAPA 8145's rated at 6v and 226a/h each. I'm testing to see how long they last with an Isotherm C-85, 3c/ft, 12v refrigerator, consuming an average .8amps. I assumed it would ...

Thanks for the replys.
The batteries are new and were left on the trailer charger overnight.
The initial reading was 13.62 and I had understood from some other thread that I should recharge at 12.2. The chart above shows I could go longer.
The refrigerator states; Average Power Consumption:- 0.8 A/h @ 12v
Max Power Consumption:- 3.5amps @ 12v
Nobody seems to think there is anything wrong so, great.
I did find there is a difference in voltage with the compressor running and not running (lower when running). Which number is significant for recharging?
Thanks, Guys-
