    Battery arrived and fits fine , haven’t tested it’s capacity yet. I’m disappointed that this battery has F1 terminals not F2 (1/4) as required by the BackUPS ES650 for which it is described as a replacement . The terminal size is specified clearly in the description but who knows what that means even if you read it before buying . My education came after it arrived and I tried to put it in my UPS . Sure you can squeeze and crimp the connector to get it to stay on the terminal but thats not a great solution for something you hope will work when the power goes out.The seller should ship a pair of F1-F2 adapters with this unit , these are a few cents in bulk but currently $4 for a pair on plus the investment of time and effort .

    Might Max is our go to battery supplier for our household UPS systems and alarm system. Why pay more when they have a quality product?

    I have ordered replacement batteries from this company before. I will do so again. Each time, the shipping was very fast, and the batteres fit and worked as described. So far, I have only purchased batteries for my battery back-up units. Never a problem. I would like to see some more advice on their site for not only replacing a battery – but upgrading it. If I could buy a better battery, that would fit, I would. I want the best battery I can get for each battery back-up. I’m not sure if any product deserves 5 stars without several months of testing, but since every battery I have received, fit, was easy to install, and worked – 5 Stars. years ago, I threw out back-up units because the cost of replacing the battery were so high. Not any more! I have purchased batteries directly from them, and through . I think buying through is easier, and if there is an issue, would likely be resolved quicker. I have never had a problem, so I will buy more as needed. Again, product was shipped very fast! Pleased with purchase! I’m giving this same review for all my recent purchases from them.

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
