    I purchased this battery to be an auxiliary battery for a VW Vanagon. Based on the dimensions listed, it should have fit under the front driver seat. Unfortunately, those dimensions and the images didn’t see to indicate that the terminals are taller than the case of the battery. Since they stuck out above the case, they would not fit in the compartment where I intended to install it without some sort of modification. I am happy with the speed of delivery and it didn’t seem to have any issues other that the size wasn’t exactly correct.

    The two 40amp batteries on my scooter wouldn’t charge any longer. These two 50amp replacements are the bomb!

    The battery was a replacement battery for a scooter and works better than the original battery. The order was painless and it arrived before the estimated date of arrival.

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
Arrived in good time 24h. In stock at Amazon

Ordered replacement batteries from Amazon they arrived quickly . So happy I can use my scooter again
Battery came charged ready to go and works good
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.
