    Fitment was exact replacement for battery pack, with the exception of the height of the terminals. They are a little bit shorter, but I made it work.

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
