    Used for my generator. Original battery lasted 3 years. I learned to not overcharge your battery by not leaving the charger connected.

    Works like advertised. Glad it fix my generator. After winter 2021-2022, I’ll have a better answer…if it lasts 4 years…it will beat the original Generac battery.

  17. Shawn

    Terminal location and shape does not match the OEM part. Works fine, but be prepared to have to bend and reorient the wires.

  32. Tri-Z

    Got this to replace a battery for a automotive battery pack. Worked okay, but would have been better if terminals were on each end in stead of the same end. Also it was the only battery I could find with nut & bolt terminals in this size to fit into the power pack. It’s a smaller power pack. Got the battery installed and drained down the battery a couple of times charging phones and tablets. Then charged back up. Used the pack charger the first time, then a smart charger to see what percent it charged too. (100%) Now if the thing only lasts.

  33. Dan Reilly

    Fit perfectly on Generac 7500E. Easy to install. Came with connecting nuts and bolts.

    Instalada en mi generador electrico marca Generac y prendio sin haberla cargada. Excelente

  40. RICKY BOBBY

    Affordable

  41. Anthony Townsend

    Terminals are about an eighth of an inch too short for many connections. While the battery seems to function fine, connecting it up was a real hassle and I had to leave a washer off in order to get the nut on.

  42. Flys4Fun

    Fast shipping Just as described, works perfect. Would buy again. For Generac generator.

  43. L acorn

    Arrived fully charged. A fresh battery. Never heard of Mighty Max but it looks to be a major maker in this small battery field.When I connected my Battery Tender to it, the battery took a small charge for a few minutes. Great. Using it in a Gererac E-7500 which requires the bolt on contacts. Perfect fit.

  44. Donald Gore

    Worked great fully charged right out of the packaging. ????

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
