I've had great luck with wal-mart batteries,my roomates battery kept
discharging overnight, so i took it in and they didn't even try to charge it,
they just hooked a voltmeter to it and said it was dead and gave me a new
battery, no reciept,previous owner puchased battery ,i think the trunk
light was staying on.then a battery i purchased for my car died after about a
year and a half,all nighttime driving with the belt loose most of the time,
they put the voltmeter on it, dead, new battery. no questions. no hassle.
