  1. jack polatnick

    Disliked the positive and negative terminals being located next to each other. Had to elongate the negative terminal wire to make the battery compatible with my generator. However, the battery is powerful and starts the generator easily.

    holding a charge is good

    Used this to replace the battery in my Champion Electric Start Dual Fuel Generator and its fired up first time without issue. Swap took 5 min and I was back up amd running. I previously put a pair of extension battery leads and quick disconnect spade terminals on it so I can quickly disconnect after use. The original leads may be a little short as these terminals are on the right side of the battery and not the front, this I cant confirm because I modified mine fro the original config. But it is the right voltage and amperage.

    I got this battery to run a home generator. When it arrived, it was suggested that we charge it before use. My husband did not wait, but put it in the generator and tried it out. The generator started and he has been using it since. I would highly recommend this battery.

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
