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.

You receive this paper slip with your new battery- register online and receive an additional 3 months of warranty! You register online and then told - oh! you also have to post an online review with a photo to get those extra months! So, here ya go.

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!
