    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.

    I had no problems installing and using these. Four stars rather than five just because I don’t know yet how long these will last.

    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.
