    Our MH gets left in secure parking for 4 - 6 weeks between trips. Should I be disconnecting the leisure batteries during this time?

    I ask because I note that the leisure battery voltage on the control panel reads 13.4v when I unplug from EHU, but that drops to 12.7v or so overnight. I have the MH at home right now which is how I'm doing these checks.

    Both batteries are new 85 ah items. Adria Matrix 670SC with Schaudt electrical control unit.

    According to the control unit, there is zero current draw but after the last 6 weeks in storage the batteries were showing only 12.4v.

    Don't want to ruin two new batteries through newbie ignorance, hence the questions.

    Thanks in advance everyone. :)

    If there’s no current draw showing, then I suspect it’s just the natural discharge rate of the battery and it wouldn’t matter if they were connected or not. If your storage is outside, you could consider fitting a solar panel to keep them topped up ?

    12.4v is very acceptable after 6 weeks in storage. Fully charged (after a settling period) they would only be 12.5v. However 6 weeks is too long to leave them without charging and won't do them any favours long-term. As suggested a solar panel will look after them. For winter storage you'll need a decent sized panel though.

    Ah, yes ... solar panel going on in October courtesy of Vanbitz, same time as they're fitting our alarm. Slight problem, though - covered storage. Ironically, to keep the sun off because we live on the Costa Blanca. Always something to mess up the ideal plan, eh? :LOL:

    Relieved to read that 12.4v is OK but noted about length of time between charges. Will just have to bring the girl out of the pound more often, I guess, until we start using her as intended.
