AGM batteries suck and most commonly abused. They are for ROUGH SERVICE ONLY (vibration and lots of shaking) and do nothing whatsoever about making car start with more amp or power but every salesperson on earth will lie and say they do.

I sold batteries by the hundreds and Optima AGM the worst one for warranty vs. price. I warrantied so many I lost count.

Yours and do as you will..............

 

Great reply- thanks. Sounds like EFB is the way to go. Any particular brand you prefer?

 

I pushed Motorcraft back in the day.
