    I needed a battery for my zero turn mower. The original battery from dealer was 99.00 . I purchased this YTZ12S because it was close to original battery specs. Its working fine and I’am happy with my puchase from Mighty Max.

    Perfect fit for above bike (manual transmission). Battery came charged with over 12V. I put it on the maintenance charger for a couple of days and then installed it. So far so good, bike starts great and I have even left the heat grips on by accident and it drew the battery down to the warning levels and shut itself off — bike still started fine. Very happy so far. Will update if anything terrible happens.

    This battery was reasonably priced and exactly what I needed for my Honda generator. It came fully charged and worked like a charm. Definitely would by this item again.

    The battery was good drop in replacement for my old Toro lawnmower even with the smaller physical dimensions.Doesn’t offer the benefits of a more expensive AGM battery, but good for what I needed.

Arrived in perfect condition
2011 Yamaha Raptor 700R battery, started right up. Has a 1 year warranty. Great deal.
Love mighty max batteries
Arrived well packaged. No information as to original warranty coverage and term, but lots of solicitations to extend the warranty coverage for a whole amazing 90 days - Wow, such product confidence! At least it’s not made in China, but is Thailand any better for quality manufacturing? We’ll see.

Arrived next day and sas very easy to install. They also offer free 3 warrany extension.
I ordered this MightyMax battery through Amazon. The Ad states it works in my GE Simon XT house alarm.
I received my battery from Amazon on March 9, 2026. The box was a little squashed but the battery was packaged well and it it fine. I installed it and finally my gate opener is working properly. I purchased 2 batteries before this and had to return them because they were the wrong battery. This one is working great.
Looks the part, I am charging it fully before install on my jet ski.
These batteries arrived in great shape with the handle on top so you can carry it screw so you can hook them up very professional looking better about them from Home Depot
