Hi all, In the short 1.5 years Ive been riding I've owned 3 different bikes. Each one at some point in the relatively short time I've owned them has suffered from a collapsed battery (well at least the 2 have, and the third Im pretty sure is [see my 'Bike not starting' thread in this forum]). Are bike batteries more prone to this? Or am I just buying cruddy batteries? Or just lucky?
