Ordered ML18-12 battery from Amazon, and arrived as stated. Now my generator is ready for the next power outage. Battery was packaged well, came with new hardware, which I was not expecting. Welcome surprise
4 stars only because this was my first experience with MightyMaxBattery. 5 stars are reserved only after multiple interactions with a company or produce. You know a clock is right twice a day.
I reiterate for me 4 star is the best rating from me on a single interaction. Hope this help Anyone shopping for a generator battery. I would recommend this produce!

I installed the battery today in my GP 8000 E Generac generator. Installation was quick and easy and the generator started up immediately when I pushed the power button.
