House batteries vs start up batteries

[Fjpapd@gmail.com]

Iam totally new to the rv world so please forgive me if i ask a stupid question. I have a Thor Tuscany AE model (2015). When i turn on the inverter it works for about 5 minutes then turns off and states low battery. There are two sets of batteries on the coach, one on the rear drivers side and the other on the rear passenger side next to the inverter compartment. Here is the stupid question, where are the house batteries located, drivers side or passenger side. Also do the battery compartments slide out for easy access. Thank you Frank

The 4 batteries on the drivers side are the house bank

Apparently you might have a bad battery or cable

Test each separately and replace the bank if they are weak

I doubt if yours are on a slide

Good luck!
There are no dumb question: just poor explanations.

I would start with checking the cable connections and then the batteries. If they are the original ones, they may need to be replaced. You can either buy a battery load tester or take them out to a local auto parts shop and have them tested. If one battery is bad, I would replace all of them at that same time. The bad battery will cause the good ones to go bad quickly. Before removing any of the battery cables, I would photograph each one and mark each battery cable as to position. A quick drawing with the battery connections (location and where each one goes) is a great tool when replacing them and getting the cables in the correct order. Don't try to do it from memory.
