Dometic Refrigerator Model 2652 - Battery drain

The way generators work - and this is why I'm trying to avoid them - is that after you've quickly charged the bank to ~80% in an hour or two, you then need to run it 5 or 6 hours to bring the battery to 100% full.

But this is kinda irrelevant because if he needs to put in a bulk amount of charge twice a day, this is still a lot of amp-hours for a meager DC circuits of the fridge. Something is wrong - either other loads running, or fridge in 120V mode.

I doubt he is FULLY recharging them if he is attempting to charge twice a day. There is a difference between FULL charge and just a surface charge. If he does NOT start out with a full charge each time, then he is spinning his wheels trying to determine his problem. Doug

BTW what is the charging voltage and how much time do you run the generator for a recharge?

Have you actually measured the current draw?

1. Even with and IF he has the Climate control, that would not drain 2 six volt batteries twice a day
2. He needs to check his complete RV for other 12 volt draws. Having the Climate control ON (if he has one) usually takes several days to drain a GOOD battery. Doug

Yes check the humidity switch. This thing should be disabled when on propane.

As it's been said, Dometic should have a switch to turn off the heater of the fridge/freezer wall.

Though, there is something wrong. What 2oldman said - make sure it runs in LP mode, duh :) ...

My Norcold - same size - has no switch, so the heater is always on, and yet it draws only ~12 AH in 24 hours on the medium setting. Propane fridge together with LP sensor (it's always on) shouldn't draw more than 16-19 AH. Your 225 AH bank should last 5 days before it drops to 50% IF there are no other loads.
