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.

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.
