    I bought this to replace the recently failed factory battery in the large emergency generator I purchased right after Hurricane Sandy in 2012. Fit in and connected perfectly. Came fully charged. Test started the generator fine twice. So all is well. Ask me in 6 years if it still works. Hope so. BTW, Mighty Max makes a similar battery with the positive and negative terminals on the opposite sides. It costs many dollars more, but has the same specifications listed in the description. The original battery in my generator was like this, but because of the length of the battery connecting wires, it made no difference to install this “opposite” new battery. I saved quite a bit. Later I noticed even more could be saved by buying the same spec MM battery with spade type terminals and connecting the battery wires with a bolt and nut. This may not work for all generator installations, but on mine it would. So, next time…..

This battery was half the price as a comparable battery from the local farm store and the same size, voltage, and composition.

I have used the Mighty Max replacement batteries in all my UPS’s for years. I’ve never had a problem with them being in use for at least 4-5 years.

Why pay more when Mighty Max is so reasonably priced.

Perfect fit

I am using these two 12V batteries to repack my 24V drop-in battery unit for my electric lawnmower. After installing the replacement cells I was able to try out my mower to my satisfaction.

Original battery had a problem and a new replacement was sent out. That's Great Service and excellent customer relations!!
This battery is for a Stanley Jump box. Perfect replacement. To help future customers I've included some pics of the replacement process. The battery is accessed via the back panel. Remove all the Phillips head screws (2 sizes) and the back panel to access the battery. I used an 8mm wrench to disconnect the wires on the battery.

I ordered the batteries from Home Depot. They arrived sooner than expected. They were a performance replacement, and Granny is up and running the seats again!
