Stop in for a cup of coffee

that has happened to me a few times. just yesterday i had to replace an advance auto silver battery for my civic
i looked at their screen while they pulled me up and i have spent $6000 dollars with them over the past 20 years AND WONDERED if THAT and the lack of rechargeability of this battery was why they quickly replaced it. the battery was 13 months old, tiny 500 amps
i paid the 30 dollar difference and upgraded the battery while i was there.
I decided to go with the AZ battery for my mower. Like most product, if you check around -You will find good and bad experiences. The biggest problem with comparing batteries is that most are made by the same 2 companies East Penn and Johnson. Many name brands are using both companies for different batteries.
Looks like East Penn does a lot of the AGM's now.
No way to know what the internall construction specs are. Mostly just going with CCA rating. While the 3month coverage on this thing is kinda weak. My experience is if it makes it past a couple cycles it's gonna be good for the season. And if it makes it till next season, even the one year the Diehard gives will be up. So, as said before, I have had good experience with my local AZ....
