I purchased this replacement back up battery for my craftsman garage door opener from Amazon and was very pleased with the Fast Shipping & careful packaging of my battery. Installation was a breeze & the product appears to be well made. Hope it lasts as long as the original DieHard battery I’m replacing that was dated 8/2016 🤞

Replaced a defunct battery in a Stanley 500 Amp Jump Start System portable pack. Totally rejuvenated the unit and possibly better than the original battery !

Waiting a few months (or before then) to see how well my two MightyMax ML12-12 batteries perform over a period of time. I have now wired 2 batteries in parallel in the hope of extending power time (24Ah) to my weather station to provide power from sun down to sun up. They are recharged during the day via a 35W solar panel connected through a Victron "SmartSolar MPPT' controller. I'll update this review after determination of their ability to hold a charge.

My old battery of six years failed and I replaced it with a Mighty Max battery. Mighty Max cranked on the first attempt. It worked great.

Small dents on box but battery was fully intact and secured with Styrofoam
