    I bought this to replace the battery in a 5 in 1 charger. So far it has worked great and saved me the 159 to buy a new one.

    I used this battery to replace my old one inside of a air compressor/jumper box mix. So far works and charges just like the old one. Battery test shows the correct voltage it is supposed to be. Amazing product for nearly half the price of others!

    I really believe that this battery works better than the one that came with the battery jump start/compresser. holds a charge longer and doesn’t take as long to re-charge great battery!!!

    Installed in used Worx mower. The factory replacement battery was pretty pricey, so I replaced the smaller batteries (14ah) with these by disassembling the case that contains the charger, and rewired these to the mower, also using a motorcycle ‘battery tender’ so they can be recharged. Works like the factory intended, but at 25% the cost.

    The terminals are 1/2 inch inside the edges so I had to buy 4 nuts (2 each side) to be able to connect the terminal cables of my automobile starter and tire inflator. Be warned! Otherwise theaters has performed flawlessly once installed.

Mighty Max Battery

Easy to install!
Battery seems ok but exterior package was damaged
Perfect fit!!! Works fantastic!! Installed in 2003 Honda VFR 800 interceptor ABS
It came quick and was easy to put on. Love that I can order it from Amazon.
Fast shipping, good value and exceptionally well packed.
So far so good. The rv loves them.
I received the battery reasonably quick. I purchased it on amazon. The voltage looks good right out of the box but I haven't tested it with a load on it yet, but I will adjust the rating when I do.
They were a perfect fit and the best price and fastest shipping. I could find highly recommend them to anyone looking for replacement batteries.
Purchased this battery off Amazon; and it was shipped by UPS. I have purchased Mightymax batteries in the past to replace batteries in ups devices. I have had great experience with these batteries.
powerful little battery
