I've had the exact opposite experience with them. I got a motorcycle battery for an older bike a few years ago, and exchanged it 3 times before I got one that would hold a charge and not shit out. Luckily it was a very easy swap, but still 4 batteries to get a good one is insane!!! A year ago I bought a wal-mart battery for a mower, which also had problems. The exchanged one was fine though. I've had a couple of their automotive batteries and so far so good, but it's early.
