To trickle charge or not, that is the question. I was never sure myself, hadn't done so previously but went w/ the advice of MK battery rep.
It's funny, I also will not put a battery on concrete for fear of that same tale.
Dunno' Ikchris, you should inform WestCo of that in as much as mine has printed, not labelled, on the back:
Replaces BMW 53030
Hopefully y'all are out riding!
