From my point of view there are 3 battery brands or groups
M/K and Deka are East Pen Battery.. MADE 100% in the USA and what starts my motor home
EXCIDE is the battery both I and my friends have had the worst expierences with, they make batteries sold under many labels. Like the ones Batteries Plus sells
And the rest. Including Interstate, Johnson, US Battery (Most of "The others" are actually either Johnson or US battery).
I bought Deka mostly because it's MADE IN THE USA.. So far I've not been dissappointed with it.
