    Purchased this to replace the battery backup in a chamberlain garage door opener. Fits fine and easy install. Has been working fine over the last few months. Nothing spectacular that would warrant a 5-star rating, but satisfied with the product.

    Just what I needed to replace battery in my LiftMaster after five years sending me message that it needed replacement. Arrived right on time and great price. Half what local dealer charges plus easy to change out. Just remove one screw, slip out the old battery and slide in the new and reconnect the two color coded leads.

    too early to review although there are no problems yet. Original battery conked out within a year and half.

    The battery was reasonably priced and arrived promptly. This is my second purchase of this product and when the time comes for replacement I will most likely buy it here.

Solid looking battery, came well packaged. Have used their battery before for my lawnmower and now looking forward to see how it lasts in my snowmobile.

I can't believe it less than 48hrs since I ordered from Walmart and it's in the machine. What more can I say except great price.
Thanks Larry

So far these Might Max batteries are good but it’s only the first day and they were on charge for 12 hrs. I’ll have to come back and do an update at some point in time. Ordered them on Amazon and got them the next day. I was encouraged by Mighty Max to make this google review and post pictures to extend my warranty for 3 months but there is no way to post pictures 🤣🤣🤣 It’s been a few months and I was able to go back and edit, so here is a video I made, the rest of the photos I have deleted. Batteries are still going strong. Update 12-11-2025

They arrived within 2 days of ordering them packaging was really good I haven't put them in my MX350 yet I hit them with my multi meter fresh out of the box and got 12.4v on both batteries so that is good
