I have to store my rv in AZ for 4 months. I won’t be able to check on it, cause I live in AK. I’m wondering about leaving a Battery Tender attached for that long. I have covered storage. I have a battery cutoff in a new Arctic Fox tt. After checking water level- Should I … leave cables/wires attached to battery as they are; turn the cutoff switch ( disconnecting it from the rV) and then attach the Battery Tender? Everything I read say check water level monthly, but I can’t do that. Advise pls. Thnx in advance.

My advice is to disconnect the negative battery cable. I do that with my car, and 6 months later it starts right up.

I would charge the battery completely and disconnect it

I have 3 battery tenders, one for my ATV and the other 2 do the boat battery and trailer battery. During the off season, they stay connected ALL the time and plugged in. I have never had to add water to the batteries even after 6 months of maintenance. They are made to stay connected and keep the batteries from sulfating. A couple of them have lasted 12 years, boat and RV 11. I'm pretty sure I'm doing something right.

Thnx in advance.we usually snowbird between early January and mid-to-late May. while we're gone I leave battery tender devices on both of our other vehicles here at home. never have had a problem.

I’d disconnect the battery and hook up a battery tender.

If your battery is fully charged and then disconnected there's not need to have it on a charger for 4 months. If it goes dead in that amount of time it was bad anyway.

I would not rely on a battery disconnect to completely remove all the battery draws. Personally I would put a battery maintainer on it, after disconnecting the negative battery cable, a good quality one. Arizona gets hot and I've read that the heat is harder on disconnected batteries than the cold.

Disconnect the negative cable from the battery. I have always done this even though my storage facility has power.
No surprises, no need to add water, very small voltage drop.

Pretty amazing that it starts right up with the negative battery cable disconnected! ;)
