    Battery seems to be a direct replacement over OEM. Came pre charged and works as it should. If something changes ill edit and give a new review

    Even with a full charge this seems very weak. Nuts very hard to align for top side mounting, no alignment method.

    Make sure you have all the right tools with you when you install because it can be a little tricky with the cool post mechanisms. I’m clumsy as it is and it can be real easy to lose the screws and to maneuver the floating nut if you’re not ready to focus on a different approach to securing the battery cables. Other than that, perfect fit, rock on!

    Battery was inexpensive and arrived in a timely manner. It has no problems starting the rig even when it’s acting up and needs to crank for extended periods.

Excellent
Mighty Max Battery
Based on 4143 reviews
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
