    The battery fit perfectly in my 1990 1200 Sportster. Hopefully it will last a long time. I usually only get about 2 years out of a battery before it dies.

    Battery fits OK and seems to work so far. My complaint is with the packaging. It comes in a box no bigger than the battery, and no packing material of any kind. As a result, one of the post on my battery was damaged during shipping. Fortunately, I was able to bend it back into shape enough to get it to work. Also, it does not come with the spacer hardware that is needed to mount it in the bike. You will have to use your old ones. I can not recommend this supplier for the above reasons. I bought two other batteries this spring from other suppliers and both came double boxed with plenty of packing material for protection, and included all the hardware needed for install.

    Happy with the item, seems to be doing the job just great. It was a little wider than a standard Harley battery for my application but it worked out fine with a few adjustments////// I reccmend the Mighty Max and the company I purchased it from.. and of course .. poppasmurf

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
