NAPA also has their battery information on file also. I had purchased a battery for my camper last year and this camper will eat a battery dead if not fully charge when put in storage. There is a battery disconnect switch in the trailer, but the leveling system and one other sensor is not wired into the disconnect circuit. I used my trailer in early August and put this back in storage, in Oct we went to get the trailer and the battery was dead. I took the battery to Napa and had the battery tested, it was dead. NAPA warranty the battery giving me a new battery with no receipt, the receipt was at home in the trailer file.
This is why I like to use NAPA stores there is usually one in every town. If I had purchased a Costco battery this would have been a 1 hour drive to the closest Costco store in my area and another 1 hour drive back to the trailer. Costco is not everywhere, I didn't even see one store in either KY or TN when we were camping there in OCT, but NAPA is.
