Hello Everyone, Im having a problem with the batteries. I put new house batteries in and a new motor battery but for some reason all the batteries are drained down so even if i unhook the motor batterie it still drains down geez. Help someone

All batteries have a certain self discharge rate. How long does it take for yours to drain down? Are you certain that they were fully charged to begin with?

Hello well i charged them up from shore power and then we put in storage mode and we came back about two days later and all of them were zero charge even the engine battery and the guy working on the motorhome is an electrician by trade and he checked it and said there was nothing registering as taking power and so we unhooked the engine battery and left it over night came back and all the batteries were dead again so we are going to change the engine battery again we think its bad but all the batteries are new like not even a month old yet. thanks for your help

How long did you charge them ? If they were dead, you would need to be plugged into shore power for at least 6 to 10 hours.

If they are going down together, the boost switch maybe on. It connects all the batteries together. It should be a momentary switch.

Some MHs don't charge the engine battery when on shore power.

Best advice is find a auto electric, 12 volt, experenced electrician.
