    Replacement for jumper box

  5. Ezequiel –

    The price, fit right in, I love it!

  6. Gordon Glaser –

    It worked as a replacement battery for a portable vehicle Jumpstarter! I don’t think I would trust it on a Diesel Truck but handles average vehicles. There is so much new technology for jumpstarting that some think something like best for other applications? It’s about the size of an ATV/ motorcycle battery but may be a little bigger. Works great? Great eBayer! No complaints! Thank you!

  13. T. Allison –

    Make sure to charge the battery completely before installation.

    i bought two of these in June 2019 for my Black and Decker push lawn mower. Worked great for a year, then gradually weakened. Perhaps usually leaving it plugged in to the charger has shortened their life, but it is the original B&D charger and is supposed to be smart, stopping charging when reaching appropriate voltage. My mower is ancient, and I have replaced many sets of batteries. the best have lasted more than 3 years, the worst not much more than one. These are very weak now after 21 months, and won’t last going around the edges trees, and other obstacles on our 1/4 acre lawn. They should, in fact, be able to mow the entire lawn, not just the edges, so it is time for replacements. I won’t buy this brand again.

  22. Richard Magee –

    Unknown about longevity since I have it only for a couple of weeks.

  23. Web Customer –

    Perfect battery replacement for my Harbor Freight 4 and 1 unit. Battery bolted right in.

  24. V S –

    Fit right in as replacement for my standby generator. Did charge it to full capacity before using. Tried and cranked with plenty of power. Tried to find it locally first, but was not in stock and cost more to get it in. Shipping was quicker than estimated delivery date. I guess time will tell how long it lasts. Overall very happy with this purchase!

  25. Glenn Weyant –

    Thanks

  26. Web Customer –

    works great but has not been in the generator long enoungh to know how long it might last.

    Good buy. Worth the price. Have only had it for a short time so don’t know how it will hold up yet. Using it with a solar charger on a gate opener

  36. Gregory Clanton –

    The battery was exactly what was needed to give the generator a kick start!

  37. Al Hirsch –

    use this to replace the battery in my portable automotive battery jumper which also has other DC power sources for camping uses like a USB charge port.

  41. Web Customer –

    Great price well below retail

  42. Lisa Hilliard –

    Got this a few months back to replace the dead battery in my portable jump start unit. It’s fit my FatMax unit perfectly. Seems to be holding a charge. I’ve been able to start 1 car that was mostly dead with it after it was connected and sat for about 3 minutes. Tried to start another vehicle that was completely dead and it would only make the car do the clicking sound thing. I didn’t have time to let it sit and see if it would start it.

  43. Jackie –

    Great battery. Using it on our backup generator.

  44. Tennessee Connection –

    Can’t rate longevity … ask me in five years. But it came quick, and was just as advertised. Installed in my home generator, and lit it right up. No problems.

  45. CU –

    It worked like a charm. Looked forever to get the right one. Thanks

  46. johnny valentin soto –

    it was not what I expected a fair product

  47. johnny valentin soto –

  48. Mikel Young –

    This battery replaced the old one exactly. Was straight forward swap. Met my expectations.

  49. Customer –

    None

  50. S Bebop –

    Fit perfectly in the original battery location, charged overnight with a trickle charger and fired up my generator. No more hand pulling the started cord.

  51. David –

    I have had to install a lot of UPS batteries and I have never had as much ease obtaining replacements as I did when I ordered from Mighty Max. A piece of cake to order as well as install.

  52. JHW –

    This was a replacement battery for a older jump start battery unit. Perfect fit in the shell of the jump starter unit, which is a very tight fit; It charged up fully in ~12 hrs. Haven’t had it long enough to rate its longevity, but I expect to have to recharge it in 3-4 months.

  55. Steve –

    So I just received this so I can speak to the longevity but it was exactly what I needed, easy to install, looks like a good product and it came with a little bit of a charge on it.. So far so good for my generator.

  56. Lee Aldridge –

    Exactly what I needed.

  61. David L –

    Replaced battery in jump starter pack. Saved about $20.00 replacing battery vs buying new pack. Can’t comment on how long it will last, but so far so good.

  74. dannyb –

    much lower price than other places. Capacity is reasonably close to the claimed number (I have to guesstimate the rating, but it’s certainly better than others that list similar numbers). I’ve only been using it a few months so can’t give a definite rating one way or another as to longevity, hence my kind-of neutral stars there.

  75. Web Customer –

    I’ve had my PS2 jump starter/compressor for many, many years. I’ve used the h – e – double toothpicks out of it. The battery would not hold a charge anymore so I looked to replace the whole unit, which is not a cheap endeavor. I took the unit apart, got the battery model info and ordered this one. This battery was half the price of a comparable replacement unit. Money well spent and saved. and it works great.

    this is the exact replacement battery for my portable charger, it works out very well.

  78. Johnny B. –

    My generator runs like a champ!

  79. Jeffrey Nance –

    I liked the fact that it arrived with a charge of 13.01 and it came with studs. I bought 2 Batts separately and each had good packing.

  80. Jon65706 –

    Bought to replace battery in my Costco PSX3 battery jumper. The positive, negative post placements are a bit different than the one that I replaced but i was able to make it work. Battery came with a bit of a charge as well. Overall size is a perfect match. I just got it so went ahead and granted 5 stars on “longevity “ and would need to update this review in a couple of years.

    2 weeks old. So far so good.

  83. Jake –

    I ordered this thinking it was a ytx14-bs motorcycle battery to fit my 2006 vtx 1300. It arrived quicker than anticipated, but wasn’t what I needed for my motorcycle. Unfortunately you cannot return a battery through so I’m stuck with it. My own fault because I didn’t read before purchasing, I was given exactly what I ordered. I looked up what this thing fits and one of the applications is a DSR jumper box…. well… lo and behold, I happen to have a dsr box that needs a battery! I put it in my jumper even though the jumper had a 22ah battery in it and this one is an 18ah, which… the box only sees occasional use and I’m not trying to start a locomotive. So far so good, but it doesn’t help me with my dead motorcycle on the first nice weekend in March.

  84. Marie B –

    Original battery died, this replaced that battery exactly. Changed the battery, charged it, and has started the generator without issue. Good replacement battery.

  91. Rick’ll FixIt –

    I was given a free non-working car battery jump starter pack. I disassembled it and found this size battery inside. After swapping it with this new battery the jump pack works perfectly.As a nice bonus the battery came fully charged and that really helped me out a ton as I ended up needing the jump pack less than a week after I fixed it.I would absolutely buy from these folks again given the opportunity.

  92. OldBollWeevil –

    Good value. I would recommend this product. It was received on time and was as described. I use this battery for my whole house generator. I received it and installed a couple of weeks before the remnants of hurricane Irma hit western North Carolina. We lost power for 2.5 days and the battery started the generator every time I needed it during the power outage.

    Great battery, fair price, quick shipping and exactly what I needed. What’s not to like?

  110. John Chidester –

    Sorry I didn’t do this review sooner but had to get my generator repaired before I hooked up the battery. I gave you a 5 star rating not only on the battery but also because of the quick response in sending the battery. and the price. The battery fit properly in the space allowed on the generator and had good power to crank over the Honda engine on the generator. If it lasts as long as the original battery, I will probably be dead and gone before it conks out. I am almost 78 years old, the generator about 25 years old now. Thanks for the good service. John

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.

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.
