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

This was a replacement for my generac generator stand battery. Exact fit and worked great.

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.

Purchase this for my portable car battery charger/compressor. The old battery went dead and this worked just fine. A lot cheaper than buying another booster/compressor.

I bought this battery to replace a dead battery in my Hustler Raptor XL Mower. Four Stars -- The Good: Exact fit, size-wise; works, starts the mower; does what it is supposed to. Arrived quickly, well packaged. The Bad: 1. the Terminal blades are parallel to the battery (I saw that in the pics beforehand, so that's on me), instead of perpendicular, like the old battery. 2. The holes in the terminal blades are small... it comes with new screw/bolts (very small) that the Lugs on my mower slipped right over (I used washers to resolve) 3. The new screw/bolts are very small, Philips head screw, oblong nut. Hard to really tighten, compared to 1/4" nut & bolt. I'd probably look a bit more next time, but hopefully that's five years away.

Fit perfect. Was the exact same battery that it replaced.

Great battery! Bought for my Solar Backup for USB recharging.

ok

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!

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.

Muy bien material

Used for our generator electric start

Exelente producto quedo a la medida

This Battery was the perfect replacement for my Motor Trend Jump Starter. Battery has nut & bolt terminals situated at 90 degrees from the original battery, but not a big problem at all. Just a little bit of repositioning of one cable and flattening of the connector on the other and it was back together and charging. I did have to add some foam weather strip to the battery like it was on the old battery to prevent it from moving in the case. Now ready again for use.
