Winter Storage without 240v

[Chris Ratay]

I will be traveling in my other camper for a couple of months, live downtown in an apartment, and my underground garage in the city where the T6.1 is parked doesn't have any power supply to plug in to.

When parked and unused, the leisure batteries drain, and I would like to deter that.

If I disconnect the negative on the leisure battery under the seat, will that take out just that battery, or the 2nd one as well? That one is easy to access - Getting to the 2nd leisure battery in the Ocean is a cumbersome undertaking.

Any other suggestions for battery maintenance during long-term storage? "Take it for a drive" is not an option

Both negatives or both positives should be disconnected to isolate both batteries .

I noticed that simply disconnecting the camper control unit fuse reduces the camper battery drain to almost nothing. Had mine at more than 70% after 5 months

Definitely worth trying, thanks. For clarity, specifically where and which is the fuse?

On my cali it’s this 10 amp that is turned around on the picture under the front driver seat

I also turn off the circuit breaker that is in the cupboard at the back of the van, that could also have played a role in keeping the charge in the batteries

The circuit breaker in the rear is the RCD for the mains 230v circuit and has no connection to the 12v Leisure Battery circuit.
