Battery

4 Sams Club 6v golf cart batteries lasted me almost 12 years (sold rig). Half of the NH winters the rig was NOT connected to AC. I fully charged and hit the true disconnect switch every fall.

Trojan says to avoid freezing storage temps when you can.

If the batteries are stored below freezing keep them fully charged.

But constant full charge is not desirable for longest life.

So you kinda have to weigh your options. I think for most people leaving the batteries installed is the most practical approach.

Actually Trojan doesn't say the above about freezing temps.

They do say:

Freezing usually results in irreparable damage to the plates and containers. It is therefore imperative that batteries that are subjected to freezing temperatures be stored fully charged or
at a high state of charge.

Removing them cant hurt. Trojan says to avoid freezing temps. If you cant avoid freezing temps keep them at a high state of charge. But trojan also says to avoid keeping the batteries at a constant high state of charge.

If the batteries are easy to access and it helps you sleep at night then store them at home. If buying new batteries doesnt break the bank then maybe the effort is not worth it. Would suck to hurt your back trying to remove a battery when the life expectancy wont be significantly increased.

I remove my batteries to save money (hopefully) and helps me sleep at night.

Thank you eveyone for the reply.

Wet cell batteries full charged with no load are fine in the cold all winter. Been doing that for 40+ years with the batteries in my boat. In Ont Canada it does get cold. Never had a problem. They discharge very little in cold weather.

That's all you need to do for the winter. My batteries discharge less than 10% doing it that way for 5-6 months in the winter.

Would be nice to know what type of battery, too. Make model age?
Some types of battery self discharge more slowly than others when just disconnected and left in place. If it's a wet cell type, you should try to keep it charged in the very cold temps of winter. AGMs a little less so, and Lithiums even less than that.
If it's not inconvenient, bringing it indoors over winter works, too.
