Found on Amazon needed ASAP….So far so good!!! The mighty max battery was Fully charged right outta the box!!! And was delivered the very next day with no problems! This was our pick because it came with a 1 year warranty! Unlike those auto stores that give 3 months and the battery dies after 4 months hmmmm

Bought a Mighty Max battery for my 2021 Polaris 450HO after having issues with my old one. It started every time even in 0 degree weather. I liked it so much I ended up buying a battery for my 2022 Polaris Ranger 500 after that one went bad. Less than a year later the battery wasn’t charging properly and with one phone call to Mighty Max they replaced it at no charge. Got the replacement in two days. Their customer service is fantastic. I would definitely buy batteries for my other quads when needed from Mighty Max.

It was an excellent value compared to Duracell.
