Once a AGM battery is cracked it will dry up over time and not work any more. If it was packed correctly then it is not a seller/shipper issue. If it was not packed well then they are at fault.
If it was packed good then ups will pay out 100.00 if there was no additional coverage placed on it.
Wish you the best on dealing with UPS they break everything.
DHL stole lots of shipments and Fedex only seems to break a sub or two a month so i would suggest fedex over the rest. Besides Fedex always pays up when they break stuff just takes a little bit.
