    Have a 2009 HD Springer soft tail CVO. I had a Mighty Max in it since Jan 2022. My wife has a 2016 Can Am Spyder F3 and she needed a new battery. Since I ordered her a new battery, I decided to put a new one in my bike too since most motorcycle batteries only last about a year. The old Mighty Max was still working great. Has been a very reliable battery. I keep the HD trickle charger on it every time I park it because I never know when the next time will be when I ride it again. Yes I recommend to anyone who is replacing their motorcycle battery to install a Mighty Max. They are inexpensive compared to other motorcycle batteries and last a long time for me.

    I have used other batteries on my ’99 Yamaha Road Star Silverado that didn’t seem to have enough cranking power. The YTX20L-BS 12V 18AH Power Sport battery does the job.

    Battery seams good for the money. Time will tell about longevity. These battery usually dont last more than 2 to 3 years I hope.

    Received battery today so I can’t rate longevity. It fit my Honda 4 wheeler perfectly. It is very nice looking and appears to be well built. It included very nice heavy duty stainless steel nut and bolt to mount battery cables with. Installation was a breeze. According to the date code on side of battery, it was 4-1/2 months old when I received it. Once installed, my 4wheeler started and ran instantly. So far, I’m happy.

    This company will not honor warranties. Have had 2 batteries fail by them in under 6 months. Just look at their facebook page for the real reviews. Save yourself the trouble and get a deka battery from napa or something

    So this is a mixed review as this is the 2nd of these batteries I bought. I got one for my tab Honda 450 foreman. This one is for my Honda shadow aero. 1st one for my tab fit and works great with 2 years of use. However the one in my shadow lost a cell and will not take a full charger with only a year.

    This battery fit perfect under my Goldwing seat and the blue color and clear top looks interesting. The battery has plenty of power to fire my bike up and keep me on the road. Great product.

Excellent
Mighty Max Battery
Based on 3474 reviews
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
