  1. DoctorG –

    I needed a replacement for the backup battery in our security system. This one was an exact replacement in terms of size and power rating as well as the connector tabs. Had no issues.

  2. Rascal –

    Fair low price and easy to install. And last but not least… It Frigging WORKS!!

  3. Todd Wilson –

    I had originally written a review where this battery had died in less than two week. It didn’t. My Fios box in the garage was out of sync and it was causing the false negative on the battery status. I called Frontier about slow internet and through the troubleshooting process we rebooted everything and now all is well. My apologies.

  4. Kathy LP –

    Would definitely purchase again. Works just as stated. Very happy with this.

    The old one had gotten oil in it and would not allow the generator to run and breath. This fixed the problem.

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.

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.
