  1. Mike ODonnell

    I liked the price. It is used for a horse trailer. How long will the battery last. We do not know that yet. So I can not respond to longevity.

  2. Richard W.

    Shipped fast. Not installed yet so I hope it holds up. If so it’s a great value

    if the unit holds its charge after a year I’d add another star.

  18. Helen Poland

    The size and connections were a perfect match to my old battery. It fully charged quickly and seems to hold the charge. I have not tried to make the brakes work with it.

    I won’t know how it holds a charge until it is in the trailer for awhile

  20. Curtis Cowdrick

    Using battery for led lights in my 18 foot enclosed trailer. Works great holds a charge for a long time keeps the 40 led light going while we load or unload trailer at a market

  21. Susan Winton

    It is the best size, weight and power required for the application. We Installed Mighty Max AGM in our light water craft to operate LED navigation lights and bilge pump. We plan for another in our Tiny sail boat soon. Thanks everyone for a great product.

  35. James E Zastawniak

    Mounted it in my 14 foot enclosed trailer with dual axles and tried the brakes by pulling the breakaway switch with the wheel up on jack-stands. Each wheel was locked so this battery is OK.

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
