    Perfect match. Easy installation.

  9. Anthony

    I can’t speak to longevity because I just got it, but arrived within a couple of days, fit perfectly into my Troy-built XP 700W generator, and fired right up. Seems to have the same cranking power as my original OEM. Great value for the $; unless of course it dies within a year or two. NOTE! When ordering, pay close attention to the orientation of your POS & NEG terminals. It’s not hard to mess up, order the wrong one and your cables will not reach. This reverse polarity has the POS on the LEFT. Worked perfectly for my machine.

    Just as needed. Came with needed fasteners.

  15. Larry M.

    After 4 years the battery in my Troy-Bilt generator finally died. I found this battery on and it fit just the same as the OEM battery. The only issue I had was not the fault of the battery, but of the installation of the battery. I had several scraped knuckles before I got it installed. After the installation was complete it started on first push of the starter button. 2 thumbs up for this battery!

  16. Bill S

    Only had it for a month so far it’s fine

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
