Thanks, I've put the solar panel on them...
I just called Costco, where I bought these Interstate batts in April... I
can't find the receipt, but they said "no problem, bring em in, we'll give
you replacements".... Costco is a couple hours away, though, and swapping
these will take a day...with the trip, so if they're going to "come back
ok". ..rather not go through that...
