    Previous batteries have last 3 to 5 years in my alarm system. I’m trying a different brand this time.

    So far so good. I installed this battery in my alarm system and it charged right up and so far is working great. Hope fully this one will last longer than the last one.

    Had two CyberPower UPS’s that were about 5 or so years old and the batteries had given up. Bought these & popped them right in. Very Happy. Just make sure you are getting the right battery size for your UPS.

    A direct replacement for the emergency brake battery on my Horton Hauler box trailer.It also runs internal lights. Hopefully, it will never be used for the emergency brake function but works well for the lights.Very pleased so far.

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
