  1. Chuki5 –

    Overall I am Content the only reason why I did not give a 5 star rating is because the battery is actually much smaller than the battery it replaced.. It starts up my ATV just fine and that’s all that I needed.

  2. Josh Macklem –

    Perfect match up for a 2005 Kawasaki kfx400… terminal screws could be an eighth of an inch longer but oh well

  3. Sarah Swisher –

    I bought this battery for one of our ATVs 5 months ago and it’s still working just fine. I’ve bought these Mighty Max batteries for our other ATVs and jet skis and they have all served me well.

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.
