It works. So far no problems after 1 month

Bought in May 2020, and it was totally dead today, October 15. Won't hold a charge.

purchased in november of 17 and in march of 20 dead dead dead wont even hold a charge for 24hrs

Spins my Ford 7.3 diesel faster than it ever has. No worries about future adding water!!!

Replaced conventional batteries with these AGM batteries. My 03 Dodge Ram 2500 Cummins turns over better than ever before. Amazing cranking power even though the rating is lower than the conventional grp 65 battery.

I put one of these in my boat over a year ago and its been great thru hot and cold weather. My batteries in my F250 with a 6.7L turbo diesel needed replacing so i want to give these a shot. Been checking our Sams store daily for a month then had to buy 2 elsewhere.. too bad Sams.. you should really keep these in stock

The battery only lasted a year and a couple months. Disappointed!!

2 of them in an F250 dead 7mos before the end of a 3yr warranty
