I ordered the battery on March 30th, and it arrived on April 2nd in very good condition. The initial voltage check was 13.14 volts right out of the box. I installed it in a Harley motorcycle.The bike started very well and the battery fits perfectly in the designed location. After hooking up a trickle charger, it transitioned from charging to maintaining in less than a minute. I am very satisfied with my purchase.
Well packaged
The batteries arrived quickly and very well packaged. One was installed in my Kawasaki KLR and fit perfectly. The battery was fully charged and I am a happy camper.
No fuss
Competitive price
Timely delivery
Purchased 27 Mar 2025 to replace previous FIOS backup battery. Previous battery (Not a Mighty Max) was purchased 6 Jun 2018 and was replaced 2 April 2025. WHOA! Almost 7 yrs worth of service out of that battery! I might have squeaked it out to the year by resetting the beeping battery.

I’ll be interested to see how well this Might Max battery performs in comparison. this is my first purchase of this battery brand.

It was delivered well packaged and was easily installed with perfect fit to the FIOS backup box. Sorry, no action shot of installation as the directions for added 2nd additional 3 months warranty extension didn’t reveal until registering the product with the company. MMB might want to include that info nugget in the actual delivery box!

Purchased from EBay online. Price was easy on my wallet. Was very surprised to see the FedEx van pulling up my drive only 3 days after placing my order! Battery was packaged nicely to the battery could not move inside the shipping box. Headed out to the shop right now to install, and try it out in my KTM 450 EXC. Thank you Mighty Max 👍🏻
Perfect match to my old battery. Arrived very quickly.
The battery on my outdoor/party speaker stopped working so I found this place to order a new battery. Great service with fast shipping and looks like a great product. I installed the battery and put it to work right away. it's been working flawlessly.
Mighty Max Battery has always provided great quality batteries for my business!

I rebuild UPS power supplies and automobile jump start boxes, and they always work perfectly. I will always buy Mighty Max!

(It would be REALLY nice if Mighty Max decided to send me some coupons or something since I buy so many batteries! 😇)
Great product
