    I was a little anxious ordering a replacement battery for a portable car starter battery. This is the second replacement over a 15 year span. This battery was a perfect match in power and size. The company was extremely helpful to work with. I would not hesitate to reorder from them in the future.

    Great strong battery. This is the second battery and I’m very happy with the performance. I’m keeping a battery maintainer on this one so I expect it will be good for a much longer time to start up my generator.

    Hurricane season is here in NC and my emergency generator battery was dead. I needed just the right size and type of battery to fit and I did not want to wait long to get it. Your battery was advertised on and it appeared to meet all of my requirements so I ordered it. And as it turned out it fit perfectly and the generator started right up. Couldn’t be happier right now. But the battery is on a low voltage trickle charger and I hope it will be ready to do it’s job if we have an emergency (major storm). And if we have no storms this year (battery is never used<, I clearly hope it will be ready and waiting for a call for at least the next three to four year.

    Two of these Mighty Max batteries replaced two nationally-marketed batteries of the same type and capacity which cost twice the price I paid for the Mighty Max. The performance of the Mighty Max in my mobility scooter is certainly equal to that of the high-priced competition! Mighty Max design, construction and materials (from external examination) are equal to those of the batteries replaced. No skimping on the active internal components here, as the Mighty Max batteries are of the same weight as those they replaced. I am extremely pleased with this purchase.

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
