Just don't buy a Smart Start AGM or whatever house brand O'Reilly's sells. Bought one and had it go dead in 2 days. Wouldn't give a refund on it so exchanged it. That one lasted a week or so. Used it about 3 months by hooking it up to a tender every night until even that wasn't enough to get it through the day. Finally took it back and made them refund it under warranty. Nothing but a headache.
