ramsay Posted May 12, 2022 Share Posted May 12, 2022 Hi I purchased a motorhome around year and a half ago. When I purchased I added an additional leisure battery as I was going to be using off grid allot. I done research and matched the exact spec of current lesuire battery located under drivers seat. This worked great and I have had no battery issues at all until recently? When the leisure batterys are fully charged according to the control panel When the motorhome is lying not getting used they are completely draining within 5 days ? When the motorhome is not in use everything is switched off nothing left on ? Is this a sign off 1 off the lesuire batterys failing and needing replaced ? Any help would be appreciated thanks.

Keithl Posted May 12, 2022 Share Posted May 12, 2022 Try fully charging them and then disconnecting one battery. Monitor the voltages of both to see which one goes flat first. I suspect you still have a load switched on, do you have a garage light or anything like? Keith. Link to comment Share on other sites More sharing options...
ramsay Posted May 12, 2022 Author Share Posted May 12, 2022 Thanks found the culprit the fan switch was on at the truma gas heater which would have been draining the batterys. Thanks for your help ?? Link to comment Share on other sites More sharing options...
