  1. JPE

    Purchased a DR field a brush hog (used). The battery on it wasn’t holding a charge and the battery direct from DR was about $100 plus shipping. Purchased this instead, fit right into the original battery retainer bracket on the brush hog, started right up. Very pleased with the battery, plan to maintain it with a float charger to make sure it lasts a good while.

  2. Gary Cannon

    it was a perfect match to the Sealake FM1217OD battery that went bad in my Harbor freight Portable Automobile Jump starter.

  3. S. Tello

    Forgot to keep the trickle charger on my old generator so the battery died. This was the perfect replacement fit for my Briggs & Stratton 8500 power generator. Very easy install – I did need to charge before using. Can’t comment on longevity as I’ve only had it for 2 months.

  4. George J. Kreiner

    I’m really happy with this battery as a replacement battery for my DR Mower. Especially since DR want 3 times the price for a replacement. I always keep my batteries on a slow charge to increase longevity, so I expect this to last just fine, but time will tell!

  5. J. N. Denenberg

    The battery in my 8 kw Generator would not start the generator after 5 years of standby use. This Mighty Max ML18-12 was a direct fit and now I won’t have to pull start the 15 HP motor for a few more years.

  6. Adolfo

    Battery was for a portable car jumper, air pump, USB charge connection and light

  7. J Dominguez

    Bought this for my car emergency car battery jumper and compressor. It came charged. I was up and running in no time. Check dimensions and connection terminal type before you order.

  8. Charles D. McCarthy

    Champion Home Generator battery replacement. Machine fired right up.

  9. Juan Garcia

    Easy replacement on my car jumó starter. After 8 years my old battery gave out instead of replacing the jumper with another modern one well over 300$ an easy fix worth the price and looking for another 8 years of use.

  10. Web Customer

    The battery works just fine and was received in good shape.

    Just as advertised. Solid performance at a great price. I needed it to replace the battery in my DR Field Brush Mower. The OEM part was double the cost for the same battery with their name on it.

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
