  2. James Long

    The battery corrected my problem.

  3. Sheri

    Works in my generator so I can push a button to start it instead of having to yank on the ripcord!

  4. don

    well made would buy again

  5. Web Customer

    Replacement battery Simple but Not easy to install . Had to move fuel tank for easy access to fasteners. Don’t know what the longevity is, it’s a wait and see process.

  6. Fred

    Just what I needed

  7. Movinon93

    Battery arrived ahead of time. The exact replacement for a 20 year old battery. I did not have the proper tools to install it, but a 20 minute visit to a local shop had me on my way home. Good value.

  8. Francis A. Bearse

    I recently installed this battery in my 20 year old Generac generator 7550 watts I can’t rate the longevity yet for the generator is still under repair I will post later my final results but so far the battery turns the engine over very efficiently and I am well pleased again Mighty Max hits it out of the park thank you so much

  9. JON T EDWARDS

    perfect match for my generator. Easy install

  10. Web Customer

  12. Bernie

  25. Juan nava

    Good

  26. Tj

    very good product! Got a package so quickly! Thank you!

  27. Slowrider5

    Worked great on my Gentron GG10020 generator. Perfect fit replacement. Put it on trickle charger when it arrived and it showed fully charged within 1-2 hours, meaning it was basically fully charged when it arrived. Great deal! Will be sure to keep it on a trickle charger so it doesn’t die as quick as my original one did.

  28. Carlos M. Torres

    worked great

  29. Michael

  34. Customer

    Don’t ever bother looking anywhere for replacement batteries except . I’ve found batteries for obsolete cordless power tools, line trimmers, leaf blowers and now my generator. No complaints yet.

  35. Phil

    Perfect replacement; exact duplicate for the old one. Arrived charged and ready to go.

  36. Customer

    plenty of power

  37. Tim H

    Purchased this as a replacement for the battery in my Generac XG10000E after the one that came with it died. Fit was perfect, and fired the generator right up without even having to charge it first.

  38. Terry & Pat Sparks

    Good Product

  39. DeniseW

    came fast and was what I needed

  40. W J Boyer

    Same form & fit as the original, so no modifications needed to install. Even came with new terminal fasting nuts, bolts & washers. I was expecting to take a trip to the hardware store to find replacement for one of the original which had corrosion/ rust on it. Then I thought I’d need to charge it before starting. But I decided to try starting the generator immediately after installation anyway, and it started it with ease.

  41. Gerry

    Prompt servicing shipping. Haven?t used the battery yet. Still looking for a battery holder for my generator

  42. KY Kathryn, aka

    same size perfect fit easy change

  43. Leonard Musson

    Excellent price. Packaged very well and was fully charged ready to go. Perfect fit for application. Excellent very happy

  44. Charlotte Berner

    Arrived on time, works great. Will buy again.

  45. AG4QC

    Seems to work well. Came fully charged and off we went!

  46. J. WOODMAN

    Well just got the battery and replaced the one in my old Generac 10000EXL generator. The battery is used for the electric start. It fit liked a glove, and cranked the generator with ease. It appears to be identical to the battery that came with the generator. Also liked not having to fool with the battery core charges too. Pretty neat, the battery also came with new terminal bolts. I did not expect that.

  47. Spoon

    Update April 2018: Living in New England, we got hammered during March with Nor’easter after Nor’easter. Lost power five different times, ranging from 8 hours to three days. This battery did its job well, starting the generator every time, first time. Although the battery gets charged when the generator is running, I also provide a trickle charge to the battery every Sunday for 8 hours (it’s on a timer), and that probably helps also. I’ll try to remember to update this review after a few more winters.Original Review: Bought this to replace the original battery on a Generac XG10000E generator. Old battery was 5 years old and no longer held a charge. Old battery also was 10 AH vs. the 18AH here, so I’m hoping it will do a lot of starts in cold weather without working out too hard. More AHs. Good.The location for this battery on the generator frame is tight, and the new battery slid into place perfectly. The battery comes with hardware for attaching the cables to the battery posts.As delivered, the battery voltage was 13.6 volts DC (unloaded). I left it on the charger overnight before using it to start the generator the next day. Worked just fine.Overall a good deal for a higher capacity battery that fits perfectly.

  48. Charles R. Lockwood

    Bough to replace dead battery on my generator. Nor planning on using it until the next hurricane of power outage.

  49. Len Segarra

    Great fit right in and started right away

  50. David Crawford

    fit perfect and has a lot of cranking power

  51. Suzie Mendez

    I buy a new one every 5 years for my generator. I try to keep it charged to extend the life. It would have five stars but it’s such a tight fit. Of course the original was a tight fit as well and had to be removed by pounding from the opposite end with a long screwdriver and a rubber mallet. I had the same problem removing a replacement to the original and I anticipate that issue again when I try and get this one out if I live that long

  52. Customer

    Arrived on time and was the perfect replacement for the original battery, I would recommend to anyone

  53. Mary Lou Crane

    Great!

  54. DavId Yaksick

    Battery fired up the generator with no problem. Only time will tell how well it lasts.

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
