    fit perfectly

  15. James M. Williams

    Fit perfect in my Century J900.

  16. dj Gmx

    Battery was in new condition and mostly charged. Installation into the jump starter for which it was bought, was extremely difficult, thought that had everything to do with the jumpstarter and not the battery itself. Longevity remains to be seen.

  17. Arbey Romero

    Fits where the old battery was perfectly

    This was a great choice to replace the Die Hard original battery.

  25. Web Customer

    Have this battery installed to replace a failed battery in a Harbor Freight 3-in-1 portable power pack. Replaced about two months ago and is still at full charge. Original battery needed charging monthly. Will see how long this will keep charge. Very pleased so far.

  31. Robert E Peters

    Fast service,works great.

  32. Rafael G.

    I charged the battery and the Diehard powerpack read 100% after charging for three days. I went to use it and check the charge percentage it read 80 percent. I?m charging it again to check the quality of the battery. Never had that problem before. Not sure if it is the battery or the power pack.

  33. Wayne

  36. C G

    great.

  37. Rod Boqua

    Working really well. Little hard getting the wires hooked back up in the unit, but that’s no fault of the battery, just a poor design on Die Hards part. Will buy from again when needed.

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
