Trojan and only Trojan offers a BCI car jar battery with other than pathetic plates. Of course, there is Rolls, but the price scares tightwads back under the bed.
There is 50 TIMES the difference between a standard golf car battery and a standard car jar battery. Thirty times the difference between a golf car battery and a Trojan car jar and 500 times the difference between a car jar and a Rolls.
The only difference between car jar batteries is the plate paste. The RV marine has a more porous cured paste. then a golf car the same manufacturer. The really big 2-volt cell batteries offer significantly harder plates. As I pointed out in earlier threads getting a 175 MCA out of a hybrid Car jar with 2-volt cell type plates would be a miracle.
I do love Costco's return refund policy. Best in the buiness.
