CCA,AH, etc.
Thanks in advance.




Size wise must fit the original battery tray and its lock. F21 size.

H7 will give you plenty of power to turn engine in CA climate, when saving several lb of weight to carry.
I am just buying H8 for my GLE and Costco have them for $183, but not at all locations.
Right now buying flooded battery in USA is impossible.
The old, flooded batteries of this size lasted us up to 13 years, when record reported on forum was 17 years.
The AGM battery in my GLE is 6 yo and I consider myself lucky it lasted that long.

Lithium as a car starter battery? seems like overkill, and possibly not even suitable, Lithium Iron Phosphate batteries ideally need a completely different charging regimen than lead-acid, the smart charging of these W212's would not be good for them, AND most Lithiums are optimized for deep cycle applications like RV 'house' batteries, and have current output limits that would not be sufficient to start a car engine.

I was just saying Walmart sold all three, not that they were correct for this application.

But the Walmart flooded batteries come with 12 month warranty, what rules them out for me, so I was forced to buy AGM lately.
I just picked up Interstate H8 for my GLE. Having the Solar gizmo, who test CA, the 1st thing I did was checking it.
The 1000 CA rated battery delivered 1530 CA.
I am happy.
