The M12 batteries have two different variations to pick from, the compact and the high capacity. Both are great for various jobs; the difference that they have is the amount of power they offer.

Product information

A: Yes, all M12 tools (FUEL or not) will accept all M12 batteries.

The first-generation M12 tools performed well. The Milwaukee M12 hammer drill came in third in our best 12V cordless drill roundup, and the M12 impact driver won our best 12V impact driver review comparison.

It delivers the power to do a wide variety of applications at 1700 RPMs and 350 in./lbs. of torque. Also included, the M12 FUEL Hex Impact (2553-20), the Fastest Driving Speed, Most Compact with 4- Mode Drive Control Impact Driver in the market.

1.5 Amps Product information

The M12™ Cordless Lithium-Ion 1/4" Hex Impact Driver features a Milwaukee® 4-pole motor and proprietary impact mechanism to provide 850 in-lbs of torque and more impacts per minute for maximum productivity and runtime. Weighing just 2.3 lbs, it's tool-belt portable and small enough to fit in tight spaces.

The main difference between Milwaukee's M12 and M18 batteries is their voltage. M12 batteries have a voltage of 12V, while M18 batteries have a voltage of 18V. This means that M18 batteries are more powerful and can run tools that require more power.

Milwaukee M12 Drill and Impact Review Performance It's hard to really showin an article, but the impact is awesome. Very smooth and never found myself fighting this tool. It drove 3″ screws like nothing and never had to push hard on the impact. The drill is just as impressive.

If you have to drill one hole it will probably be fine but take some time, if you're drilling 20 holes all at once it's not what it's designed for. This being said I love my M12 Fuel Hammer drill, it has surprised me on a number of occasions!

Most of us assume the car battery belongs to the 12 volts category, but not all of us are aware of the ampere rating of our vehicle. An average car battery has a capacity of around 48 amp hours; when fully charged, it delivers 1 amp for 48 hours, two amps for 24 hours, and so on.

Even though most car batteries are only 6 or 12 volts, a 12-volt battery can produce as much as 600 amps. Amperage can be thought of as the volume of electricity that's generated, but the voltage can be thought of as the “pressure” of the electricity.

Milwaukee M12 Fuel Impact Driver Performance Despite that, the impact rate remains the same at 4000 IPM. The torque also gets a nice boost, jumping up 200 in-lbs to reach 1500 in-lbs in mode 3.
