The napa legend costing 140 is pretty good, it claims 1080 CA and 185 RC - which is very impressive, Recently helped a guy install it in his BMW E39.

The pep boys Bosch is 1000 CA and 120 RC (?) IMO its pretty strange.

The advance autoparts autocraft gold is very good too - cheap to boot. Interstate are good but a great deal higher in price. - compared to the Advance auto one its nearly double in retail.

Interstate Battery Systems of Houston is selling grp 93 blem items for 60 bucks a pop with 3 months warranty - I have used one of it in an altima and its pretty good, but a recent purchase by my FIL for his van made him go 4 times in a month to get a replacement. The last he got pretty much looked like a new one.


For your diesel get the closest to the factory specs which speaks of both CA and RC, and if anything goes beyond 5 years in service, you are at point zero in loss - as you got the max life out of it.

Five years is not the maximum life of a battery. And I won't even ask what "point zero in loss" means.

In my experience with cars/trucks etc. five years from a retail market SLI battery is right about the EOL for it, at that point your battery cost has been justified and in my books it becomes zero point, You may experience different if you have some botique brand or some other extreme (arctic duty) battery.
