I suspect you are correct.

Rather than explode it and myself,
I decided to do the Canadian Tire Motomaster "72" route last weekend.
$109 for a side (and top?) terminals model with a 2-6 year warranty.
2 unconditional replacement upon failure/6 pro-rated.
$10 back for the old one, net around $112, taxes included.
700 CCA, slightly better than the Delco it replaced, and it has 2 cap sections
to gain access tthe cells, if necessary, even though it's touted as maintenance free.
Sometimes replace beats repair. :P o
So far, so good.
