    The battery fit in the casing as good as the original battery.. Charged and still holding charge. Great battery for the buck.

    I have an old jump starter that the battery had failed on years ago. I was just going to purchase a new one until I saw what the prices looked like. This battery is less than one third the price of a new jump starter and with just a bit of elbow grease to clean up the old one, it was back in business.

Mighty Max Battery
Based on 4228 reviews
Battery arrived in excellent condition. Even though it is the same 9ah size battery as the original one I am replacing, it is a slightly smaller size package requiring me to add extra washers as spacers on the battery hold down bolts. No big deal just be aware you may need to do the same thing. I hope this one lasts as long as the previous brand did.
Fully charged when delivered 03/28/2026.
