    Holding up very good after a year of usage. Have lost power several times and they kept things going for a long time. Recharged with no issue

    Used to replace the four cells in a APC SUA2200 tower. Batteries dated only 2 months after manufacture, so I expect a long life. Shipping was very quick, arrived just a few days after my order, a 48lb box delivered by Fedex. All the posts lined up with the hardware from the APC RBC55 battery packs. I used double sided carpet tape to bind the cells together, and put on the original APC plastic terminal covers. Took me about 35 minutes start to finish, well worth the savings.

Needed a new battery to start off the mowing season! Thanks Mighty Max!
Arrived just fine. Installed into my Chamberlain door opener. Fit just fine. Have yet to see if it works.
Great choice👍🏻
Purchased a MightyMax YB9A-A battery for a Kipor Sinemaster KGE 3000Yi digital generator. The battery fit perfectly and started the generator with no issues. The price was very reaonable and everything works great!
Can't speak for longevity, but battery was delivered at the promised voltage and CCA. For the price it's worth the try — will update my review if any premature failures occur.
The ML9-12 NB battery was purchased for a replacement battery for my generator. It was charged and ready to go out of the box. The 2 bolts that were included for the terminals were a nice surprise.
Great product
Shipped securely
I just reordered my mighty max. I'm replacing the one from 2 years ago. I believe that's pretty good for a battery like this. Always starts my mower right up.
Purchased from Amazon to use in my Polaris quad.
Great item. Just the right size.
