    Battery arrived pretty quickly and was in perfect condition. Already partially charged and didn’t take very long to fully charge with trickle charger. Hopefully it will last for many years of ATVing.

    The battery I received worked great, but the positive post was bent up. It almost looked remanufactured, which is fine just did not say it was. Overall worked good, a little tricky to get positive cable connected. Priced right

    Exact replacement for a 2008 Honda 400ex. Fits in the stock battery hold location and fires up out of the box. Exactly what you need

Mighty Max Battery
Based on 4174 reviews
I ordered it from Amazon and it got here fast
I’m back in riding business thanks to the new battery…varoom!
Fits perfectly, contacts are correct
Old battery wouldn't hold a charge. Got this off of walmart online. Very pleased. More amps. Fast efficient delivery. Reasonably priced. Highly recommend.
Now working great! Fully charged
My battery arrived well packaged in a very heavy duty box. The only thing negative I could say is that the red terminal was bent upon removal from the box but I was able to bring it back up enough to install the bolt and cable using a pair of channel locks. My lawn tractor started right up after installation. This replaced a Might Max battery that was OEM.
Great purchase!
Ordered YTX20L-BS and received it very fast 💨 n Amazon. Packaged very well and sealed in plastic bag. Purchased for my Honda Goldwing 1800 motorcycle. Very happy with this battery.
I bought a pair of MightyMax ML50-12LI batteries for my Pride Victory LX Sport mobility scooter. I purchased them directly from MightyMax late Wednesday night and paid the $4.95 expidited shipping fee and had them early Saturday afternon. You can't beat that. Amazon wanted a week for shipping. I did have to buy a new charger made for lithium iron phosphate batteries as the original batteries were sealed lead acid batteries. Hoping for more range and maybe a tad more top end speed. I'll try to update this review after using these batteries for a while. So far I'm happy with my purchase.

After a day with my new lithium batteries, I'm very happy with them. the scooter is much more responsive to the throttle and a lot better off road in the grass and with inclines.
This battery went to my Mercedes-Benz ML 350. It is a third of the cost of the battery you can get online and it is a fifth of the cost of the battery you can get at the Mercedes-Benz dealership. It works just as well if not better.
