    Casing is 1/4″ to wide for vehicle. Purchased for our 700cc quad/4 wheeler, it uses a 20 series motorsports battery. The casing on this battery is just slightly to wide to fit in the battery compartment/tray. I purchased a Mighty Max 18 series battery (40 less cca) and added a dense foam piece to fill the space. The size is why I posted a 3 instead of a 5, I have never had an operational issue with a Mighty Max battery, they do the job well and are cost effective compared with bike shops, farm equipment and auto parts stores. Local retailers only carried “L” versions of this battery and I didn’t need reversed terminals.

    Bought this after looking at a lot of other batteries costing 2x as much or more from many well known manufacturers. Installed in my 1994 Sportster and can honestly say I would buy it again. I don’t have the test of time yet behind me but as far as fit, functionality and compatibility, it was spot on. Well worth the purchase, spend your extra money on gas instead and go riding.

    The company sent me a replacement right away and it’s going on 3 years now in a Sportster. Just replaced a previously purchased battery that lasted 4 years in a different bike. This bike has high compression and a high torque starter so it’s a good test of the battery. 4 years! I’ve had big name batteries at twice the price that only last about a year. Old review – Battery arrived DOA and unusable.

    Bought this for my Kawasaki Prarie 360. Perfect fit, and it seems to be holding up well.

    Product and delivery has been great. I have had this for two months now and it starts my F8 snowmobile every time with no problem

    Mr. Guest –

    Battery fits as advertised. I don’t maintain my batteries like I should so I wind up replacing them every season or two. The more expensive ones don’t seem to fair that abuse any better, so why not go with a more budget friendly battery?

Mighty Max Battery
Based on 5437 reviews
A+ my second time buying these batteries
Exactly what we needed.
This is an awesome Mighty Max battery and came fully charged and works great. I’m very happy with my purchase. Thank you.
Hi looks good
Just replaced A battery for my jump box I will see how it works out! I did have to drill bigger holes in the Terminals for the bolts so far these batteries have been excellent for everything else lawn tractors, generator Battery

New battery for emergency lighting excellent!

Second battery for my second classic Exide emergency light!
And another one for my second emergency light

This one is going in on Bluetooth speaker in my garage
This is the second one I bought in less than a year, and they both have worked great
Perfect replacement for the factory original, at a lower cost.
Got new battery faster than expected, for lawnmower. Came in a box neatly packaged. Charging for 24hrs, light is on, meaning it's charging correctly. Can't wait to turn it on.
I ordered these babies off of Amazon. Since I'm not sure how full they come, I have them installed in the scooter box and in a maintenance (opposed to trickle charger, which I recommend), and will do a test run tomorrow if no rain. Great reviews convinced me to buy these. Plus being manufactured by a US company was the other deciding factor. Also my brother bought these same 24 V/ 15 Ah Mighty Max batteries and he's mid-way through year 4 with no noticeable power loss on his scooter. No brainer.
Works as it should.
