So this 88 Burb I just picked up puked a battery last week. Fire up the truck. Drive to the store. Away from the truck no more then 5 minutes and come out and get "CLICK". Barrow the battery for a few day's out of the 79 I just sold and hasn't been picked up. Been sitting so the charging was good. So I dig through the paper work the PO (Previous Owner) gave me and find the recipt for this Wallmart battery. 2 years old to the week three year replacement. Head out to Wally World and get in line behind another guy with a simular battery that is 2 years old and dead. Hmmmm Good battery I surmise. So lacky at Wally world hooks it up to his machine...Hay this battery is bad! Yeahhhh hay your smart! So he calls up to the service desk says it's a exchange. Get in line behind the other guy. My turn and I hand them the recipt. Woman does the exchange and hands me $11 bucks. I don't argue LOL. two year old battery that I didn't buy in the first place and they give me a refund of the price difference nad a new battery.
