Why do you say that?
All batteries leave the factory dying. Plus locally in the morning a new 650 amp batter will be a 325 amp battery when it is time to go to work.
Smaller may be better in some things but not so much in batteries in my experience over the decades.
If not driven daily we find it is best if our 2000 Towncar is plugged up to the $20 solution we bought in the charger department at WM to make batteries last longer. The parasitic loads become more noticeable in the winter in our region.
He's talking about the same physical dimensions and group size battery. You can have the same physical size battery but something like the Autocraft gold has more plates to achieve more amps than an Autocraft silver of the same size. That is probably why many recommend the silver over the gold, less plates equals less components to fail.
The AAP batteries are JCI but not all AZ batteries are. I noticed at my AZ only the Duralast gold was JCI but the cheaper variations were not and the Platinum is totally different AGM.
OEM or Interstate if you don't collect your pennies. I don't know what is going on but I see JCI oem batteries outliving other JCI batteries. Is it cherry picking?
Just saw a Motorcraft JCI battery in a co workers car completely killed by dead alternator dated 6/2006. Leaking and acid coming out a little and he replaced the alternator and jump started the car it's been working great in this cold weather since. I never see that with retail batteries of the same age. Starting to think all JCI aren't created equal.
Since they do not list plate counts like years ago I go by weight today.
The higher the amps the longer the life today and they do cost more because they contain more lead.
I think the logic that more plates means higher risk of failure is not supported today. Today the higher the amp rating the longer the company stands behind the battery typically.
