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

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.

Bought it for my cheap Stanley jump box bought from a pawn shop as is for $15. Original battery was a dead 7 amp hour. NOW its a 9 amp hour and the battery is an exact fit. Works better than it ever did new.

Exactly what i needed. Was charged up ready to go. Fast shipping. Extremely satisfied. Good value. Very competitive pricing. Correct connections. Quality battery.

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.

I purchased to r place the battery on my zero turn. It came fully charged, and it was the same size to replace the dead battery.

Easy replacement for my battery backup unit

Bought to replace the old one in our booster/air compressor. Fit perfectly and it was cheaper than buying a new unit.

Been working for 2 years without issue.

good quality at reasonable price

Exelente producto quedo a la medida

Used for our generator electric start

This 12 Volt 9 A/hr. SLA Battery with nut-and-bolt terminals is a very good same capacity replacement for use in Canadian Tire's 120 Watt, 600 Amp booster pack, catalogue number 011-2002-8. The width and depth exactly match the original, but the height is about 3/8" shorter than original, requiring me to make a spacer to put against the bottom. The original battery had developed a dead cell after 8 years of service, but all the box's features worked so I decided to replace the battery. Tip on opening the box: there is a screw hidden under the centre of the label near the flat area under the handle. Rub the upper centre of the label with a finger, to find an oval-shaped depression.
