Some-not all, AMG batteries, are truly worth the premium price - even if one never goes off-road.
I've been running Optima batteries, for 15 years now.
- first 2 red tops lasted 9 years each, in wife's car & my truck / USA made, back then
- but red tops, don't like to be run down
- I realized the yellow top deep-cycles, is a better design
- so when my old red tops finally bit the bullet / I switched to yellow top
But Optima closed their USA manufacturing plant / now Optima makes their junk in Mexico and carry a short product warranty.
Sears Platinum if memory serves me correctly, are AMG's made in the good old USA.
Since I'm from Canada - Canadian Tire has a new AMG deep-cycle battery, also made in USA (maybe by Exide)
- comes with a full 5 year full replacement guarantee, two top post sizes priced at $169 & $189
I even use an AMG battery in my vintage John Deere 318 garden tractor, with hydraulic snow blower.
