Re: Amp/hour test is way off-
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- Eber338Views0likes0CommentsAmp/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 run almost 10 days on a charge. Adding variables and other minor loads, at least 4 days. After 24hrs., my voltminder reads 12.29 with compressor running. Other known loads are the voltminder, small fan on Nature's Head which draws milliamps (?), and a indicator light on the new 4 stage charger/converter from Best Converter. At this rate, they would need charging after about 30 hours or so. Am I wrong in expecting too much? Math error? Other? All lights have been converted to led and there's a 100w solar panel coming to keep batteries up. My only concern was the actual use of the refrigerator. Yes, refrigerator was prechilled and contained three, 2liter bottles of ice. Thanks for any help- Eber3.6KViews0likes17Comments
