Good fit for my jump starter portable carry case!
Battery fit just like old one, functional as needed, weight same as old one, used for 12v jump starter automotive & great value for cost. Replaced old battery with this type, holds charge for couple 2-3 months!

Have bought 3 and they all have all held up well
Great battery. These fit not only my generator but also my kids G wagon power wheels. They seem to last just as long as the original battery if not longer. I’m thinking of trying to run 2 of these because we have the space.

Good price looks like a good battery
Got this battery to replace the old one on an everstart jump pack it fit the size and voltage and amp hours. So far it works. Not jumped anything yet .so we will see what happens .but it did run the air compressor and charged a mp3 player .

good purchase.
This battery is of special size. Make sure you purchase the correct size. It works great! Used it to refurbish a battery jump starter unit.

DeWalt 7000 generator starter battery
I bought this to replace the electric start battery on my DeWalt 7000 generator. I'd say it was more or less an identical replacement for the OEM battery. It fit properly, no issues with terminal size and it works as expected.

Direct replacement for Schumacher power pack
Replaced the old battery in our Schumacher portable power pack/jump started. The terminals were slightly different but that did not pose an issue for installation. Once connected the Schumacher power pack began charging when it was plugged in. After it was fully charged I tested it by jump starting a vehicle, all went as it should.

A good battery from a great company
Ordered the Mighty Max that my generator owner’s manual said would work, but it had the wrong connectors for my generator. Contacted Mighty Max for help, and they immediately sent me a different model battery. Installed it on my generator, and the new battery promptly had the generator working. I couldn’t be happier, both with the battery and with the service that the Mighty Max company provided. A first-class operation.

Big enough to start a large gas home generator. I'm happy with it.
Installed this on a 3200/4000 peak home generator that was originally purchased from Harbor Freight. It easily turned the engine over and started the gas generator. Exactly what I was looking for.

I got this battery to replace the one in my car jump starter unit. it was the exact size and fit the box perfectly. It was almost fully charged and it has new bolts with it if you need replacements. I would buy it again.
