Lead Acid Battery - 2 Cells No Float

K, hope the new rig works out for you.

Mex will have to answer about why the high SGs. You will know this, but IMO put a load on that battery to see if it holds up under load, even if its voltage isn't too bad with no load. ( Same with the other two just in case of course)

If it does hold up, it would still make me nervous to bank it with the other two for very long.

Hey B,

Thanks! Me too.

Yeah, I sent a PM to Mex. I figured this question was well above most of our pay grades. I'm sure we'll see him when we see him.

Unless someone smarter on the subject than the two of us has another idea, then I'm inclined to agree with ya'. I was thinking maybe there could be a way to replace the electrolyte, but the whole thing is just too odd. I can replace it for less than a hundred bucks and then sleep at night. Of course I'd prefer 3 identical batteries "new off the truck," but... it seems a shame to just get a core rebate on those 2 with such good SG figures.

EDIT: Come to think of it, with just the 13.x volt float charge spread across three batteries, I probably wouldn't be too concerned about that weak player messing with the rest of the bank. I think the larger concern here is total capacity and fewer minutes of generator noise at the campground. Peukert... and so on and so forth.

But now what do you think of the 2 GC2s plus 1, 12V G29 idea?

The GC2s would be easier to restore following successive 50-90% cycles. And they should fair better with solar. I'd just have to hammer the 29 a little more when I got home to combat our good ol' PCL (progressive capacity loss.)
