Mighty Max Battery
Based on 3766 reviews
Excellent Product! Thank You
Worked perfect and was a great price at Northern tool equipment
This is my second Mighty Max battery for my home portable generator, and neither has failed me! These first generator was used during the Texas heat power outages. My most recent purchase was for the sub-freezing temperatures caused more power outages. These little batteries are perfectly named – Mighty Max! They certainly are mighty and are maximum in dependability. I never doubt that little battery will fire up my generator and keep it humming, which means my home will stay cool during the summer heat and warm during the winter freeze. Kitty, how is it out here? Is it out here kitties
So easy to install and worked like a charm right away!
