Wal/Mart and Sam's have changed lately I was there and their battery warranty has gone from 6 months to 3 years now on free replacement that is a good warranty IMO
I have never had Wal/Mart, Costco or Sam's do a load test on a battery the few I have purchased from there they just looked at the date and handed over a new battery but Wal/Mart is touchy about having a receipt
3 years, NAPA is 18 months. Color me cynical, if they are not going to replace the battery without a fight the free replacement can be a 100 years. Screw me once shame on you. JIm
