I recently replaced the stock battery on my 2014 Sport 22 with a new 12V 100Ah AGM Sealed Lead Acid Battery UB121000 Group 27.

My question is this...

After one night with only the fridge (on propane) running, I'm already down 1/5 on the stock charging meter. Is this normal? After about 4 days, the battery is completely depleted. No, I haven't tested the load, need the hubs to do that for me when me and the dog get back home.

Any advice would be great. Thanks in advance.

4 daze on a single 100ah battery is not bad at all. Realize that it has 80ah of usable power.
Discharge to 20%=longer battery life.

I re-charged our Lifeline AGM's at 11.9-12v, they lasted 11 Seasons, still in service as B/U power for the sump pump.

What was 'compleatly' on the meter?

@Robert Cross

Thanks for the reply. I didn't realize that the fridge electronics load and whatever else runs all of the time would deplete the battery so quickly. I thought it would be negligible, but I guess without testing the actual load, there is no way to know. We will do that first chance I get.
