Customer Reviews

Customer Review: “Works great. My old original battery was 19ah. This one was 20ah. It fit perfectly. So it’s a little stronger than the original now. I used the booster pack 3x now to start my truck in extremely cold weather. My battery wouldn’t start my truck and it started right away with the booster pack.”

Customer Review: “We are using this with a 2 amp 12v trickle charger to run our Diesel heater if our off grid battery power shuts down to keep the fans running. (Glow plug when hit stays on without power use as oil heats it automatically drawing 1 amp.) Small size and comes with hardware. Standard Battery quality to be expected. Well built. Terminals very solid posts.”
