SiO2, Lead Crystal, Soneil Batteries

I read what he said. I doubt I'd be leaving any batteries in severe temperatures like that, no matter what the specs are.

Well, the OP’s information is a bit sketchy, I’m still confused by the reference of amp/hrs capacity vs amps current - some clarity is lacking...

My lead acid bank doesn't mind at all, and solar keeps it 100% charged.

Hot weather is much more damaging to LA batteries, and mine showed a significant loss of capacity when cold.

why would you have to remove them? just have a shut off switch and turn them off when you leave.

Steve,

You can't recharge Li when they are cold. If it is -30, it may take HOURS of furnace run time to warm up the RV and the battery bank, even if it is in the living quarters. So it may be impossible to get the battery bank to where it is possible to recharge it, unless it is a massive bank to start with. If you roll your own--fine--but if you are buying drop in it may cost a pretty penny. The alternative is to remove the batteries to a warm environment and then return them to the RV.

I realize this is an outlier possibility--but it is the situation in which I live and RV in.

who was talking about recharing them when cold, he said he would have to take them out for long periods when he wasnt there. no, you simply need to turn them off and let them sit. sitting in the cold over the winter wont hurt them and in the spring when you go back to your seasonal site you just turn the switch back on.

maybe we need some claification on what he ment by that statment but I took it as removing the batteries for the off season when they wernt using it.

Steve,

I am not willing to move 7 batteries and the starter battery and the generator battery at -30. Now do you understand why cold weather performance is necessary for me?

Oh are you the original poster using a different name? I didnt think this was about you...

First of all this is now a moot point. We already own a set of Soneil 260 ah batteries, but.....

We have a seasonal campsite .8 mile from our home. In the fall I store the camper near the entrance where the campground owner blows snow, so we can take off in Jan/Feb to head south. In that location we are not allowed to use the campground electricity. We use solar to keep the batteries charged and sometimes use the camper for overflow guests at our home. I want to immediately use the batteries no matter how cold it is outside. Azmuth had no problems with this scenario, since cold weather use is one of SiO2's attributes. Not only do I want to be able to use the batteries in cold weather, I want to be able to charge them without having to run the furnace. When I talked to Battleborn they weren't too keen about either idea.

pianotuna seems to understand my reasoning.

I'm not here to argue though. This is my rational and it works for me.

I started this thread to find other users. Steve, are you another user?

Enjoy,

As I stated in a previous post I've corrected my grammar.

Enjoy,
