    Bought this as a replacement for my RE Himalayan. The stock battery pretty much sucks, so this has been exponentially better. No issues on startups like I was experiencing in owning the bike the first few months of owning it new. The nice thing is if I decided to mount it horizontally, I could. Little bit lighter, kind of a pain to get in the battery box, but that’s not their fault, poor design by RE, but all in all, value, and overall performance is worth it for me.

    Works well in my Honda TRX500 and TRX420 although shorter than OEM battery so time will tell if it has enough capacity. Really like that it actually shipped to Alaska!

Mighty Max Battery
Based on 5239 reviews
Packaged very well with terminal bolts, washers and nuts included. Good looking product. Excited to incorporate it into my car audio system.
The Battery delivery 🚚 turnaround time was faster than I expected ! Now moving on to get the installation done by a Battery professional.
Perfect fit. Look forward using this unit often.
Good battery, perfect fit for the Toro Recycler push mower. Came well packaged and fully charged 12.76v. Model ML3-12. Photo shows all the packaging.
Super easy install, less than one minute.
Beeping stopped immediately
The one I replaced today was 3 years old with no issues. It finally gave up. Trying another one. Hope to get the same outcome.
Arrived in great condition and will now extend the life of our Pathfinder 320 speaker, Whoo, hoo!
Got mine on Amazon and it got here quick, I got it installed and running. Thanks again
Arrived as promised, in perfect condition. Installed and cranked up the mower fast. Great price.
Second set I have ordered, these have been very good batteries especially at the price point charged. No problems whatsoever with them!
