    Battery was an exact replacement as advertised. It took about 3 days for the replacement battery to show as fully charged on the garage door keypad but remains fully charged now.

    The purchase experience was simple, the battery arrived before I expected and was easy to install. Couldn’t point to anything that needed to be improved upon.

    Initial package didn’t make it, i.e. lost in shipment. Seller very promptly issued new shipment which was received quickly and in good condition. Battery installed easily and works fine. Only reason not 5-star is due to unknown battery life. But, out of the box seems fine. Good value. Recommended.

    Replaced old backup battery in craftsman garage door head unit last week. Too early to tell how the new battery performs.

    Original battery died after nine years. The installation of this inexpensive replacement is very easy, and it fits perfectly.

    Reasonably priced. So far, no issues. Make sure you check the exact battery (A or B) and follow directions disconnecting power and you’ll have no problems. I bought two so I wasn’t going to be hearing a beep from the other side in the near future. Quick shipping.

Mighty Max Battery

Arrived quickly. Even got a sticker with it.
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
Item as described and perfect fit and arrived on time
Battery arrived in a good shape package strait to my door steps
Arrived just in time to power my generator here in the cold Maine winters. Excellent service!
Arrived quickly from WALMART.COM. Perfect size and proper placement in my generator. Installation was easy. Generator fired right up. Battery came fully charged.
New battery. Ready for cold weather!
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
