I am debating on buying a Optima charger. Took the battery in this week to parts store and left it overnight.
Still dead 11.7 volts. I have had 4 Optima's 2 Red & 2 Yellows now down to 1 Yellow. I just hate giving them more $$$ for their crap. I hear Odyssey make a good AGM but pricey.
Funny my tractors have had the best Batteries. John Deer garden tractor finally replaced OEM battery after 22 years. My 38 hp Kubota still has original battery 17 years old.
None of my car batteries last much more than 5
Some years ago I read an interview of a Johnson Controls engineer. He said that all of the different brands of batteries they make have exactly the same components but the better ones have more of the same plates as the the cheaper batteries. He said the heavier it is the more plates are in it so buy the heaviest one you can find. When he was asked which one that would be he said John Deere.
