    I was pleasantly surprised to get this ahead of the time it was promised. I am replacing the original battery in a 15 year old jump box.

    I needed a replacement for the battery in my portable vehicle jump starter (the original battery was finally dying). This was the closest I could find (slightly higher capacity) and the dimensions listed were slightly larger than the original, but I figured I could make it fit. It arrived well packed and protected, and when I checked it against the original battery it was exactly the same size. I installed it, charged it, and it has restored the operation of the jump starter to like new.

    Ordered as replacement battery for my cordless mower. Much cheaper than if purchased original brand, yet seems to hold the charge very well and to put out pretty good power for an electric mower.

    I bought it as a replacement for a NAPA jumper box. Exact fit, put it on charge overnight and used it the next day. I saved at least $75 by replacing the battery rather than a new jumper box. Totally happy with it.

    Time will tell, but so far so good. I bought a pair of these for my APC battery backup. The OEM batteries tend to go five years or more so I’m hoping for the best. The dimensions were right on and they were fully charged out of the box.

    Batteries brought new life to my mower and it became all powerful – well at least enough to comfortable mow my entire yard. The batteries came in good shape and well packed; they fit exactly in my Black and Decker cordless lawnmower; and they work great. I need to find out how to recycle my old batteries for free and it would have been nice to have received four strips of foam tape so the stacked batteries didn’t clatter and vibrate against each other.

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
