Mighty Max Battery ML9-12NB -12 Volt 9 AH, Nut and Bolt (NB) Terminal, Rechargeable SLA AGM Battery

I ordered this replacement battery for my Generac generator. It worked perfectly. It gave me a sense of security before the bad weather came in.

Battery fit just like old one, functional as needed, weight same as old one, used for 12v jump starter automotive & great value for cost. Replaced old battery with this type, holds charge for couple 2-3 months!

Got this battery to replace the old one on an everstart jump pack it fit the size and voltage and amp hours. So far it works. Not jumped anything yet .so we will see what happens .but it did run the air compressor and charged a mp3 player .

This battery is of special size. Make sure you purchase the correct size. It works great! Used it to refurbish a battery jump starter unit.

This product was in stock at our local Amazon warehouse and I received it the next day after ordering. It was very well packaged and checking it with a voltmeter, I found it to be nearly fully charged already. I used this battery to replace a 13 yr old battery in my Black & Decker Workmate 250 Jump Starter. I have used this jumper a few times over the many years that I have owned it to start pickup trucks and cars when the vehicle battery failed. It has been a lifesaver. I also like the built-in 12v DC accessory outlet and built-in power inverter with 120v AC grounded outlet. I have taken good care of it and kept it in it's original box for storage/transport inside my truck for years, and it is still like new. When the old original battery in it finally failed, I was afraid I would have to trash it. And these compact units are not made anymore. But then I searched around on YouTube videos and learned that the battery can be replaced. I was able to easily find the correct battery replacement on Amazon, and it was pretty simple to remove the old one and replace with the new one. And when I got it back together, my jump starter/portable power supply runs like new again. I then connected it to a wall outlet and topped off the battery to completely full, which did not take very long as it was almost there already, right out of the box. 36 hours after removing it from charging, the unit is still showing full charge, and all functions are working perfectly. I am confident now that this battery is going to be every bit as good as the original, and should last me a good long time. I am very pleased with the quality and appearance of this well-made battery, and I highly recommend it.

Direct replacement battery for a Generac generator. Shipping was very good, came well packed and no damage or problems. In my experience, using a battery maintainer will help it to last a very long time, since most generators aren't capable of recharging the battery when they're running.

Ordered the Mighty Max that my generator owner’s manual said would work, but it had the wrong connectors for my generator. Contacted Mighty Max for help, and they immediately sent me a different model battery. Installed it on my generator, and the new battery promptly had the generator working. I couldn’t be happier, both with the battery and with the service that the Mighty Max company provided. A first-class operation.

It works just great

Perfect for my Generac generator

Muy bien material

I got this battery to replace the one in my car jump starter unit. it was the exact size and fit the box perfectly. It was almost fully charged and it has new bolts with it if you need replacements. I would buy it again.
