Battery Life

The Milwaukee M12IR-201B impact ratchet comes with two M12 Red Lithium XC 2.0 Ah batteries. These compact batteries offer plenty of runtime for most automotive fastening tasks. With a 2 Ah capacity, you can expect around 30-60 minutes of continuous high torque fastening from each battery. The batteries feature Milwaukee's Red Lithium technology which helps them perform better in extreme temperatures while also providing fade-free power.

One of the best aspects of the M12 batteries is their rapid recharge time. Using Milwaukee's M12 charger, the batteries can be recharged from empty to full in around 30-40 minutes. This allows you to quickly top off the batteries between tasks or swap between the two for continuous work. The charger has indicators to let you know when each battery is fully charged.

Overall, the battery life is excellent thanks to the efficient brushless motor and compact 2 Ah Red Lithium batteries. The runtime is sufficient for most automotive jobs and the rapid recharge ensures you won't be waiting long to get back to work.

Size and Weight

The Milwaukee M12 IR-201B impact ratchet measures just 9.6 inches long, making it very compact and easy to maneuver in tight spaces. Despite its small size, it packs a lot of power.

It only weighs 2.1 pounds with the battery installed. This lightweight design reduces fatigue when using the tool for extended periods. The dimensions are ideal for working under the hood, inside cabinets, or any other confined area where maneuverability is key.

The compact head on the M12 IR-201B allows you to squeeze into spots that a normal impact wrench could not reach. You can drive fasteners in those hard-to-access areas thanks to the short length and slim profile.

The small stature does not mean this tool compromises on power or performance. It delivers up to 115 ft-lbs of max torque while remaining lightweight and nimble. Whether you are an automotive technician or a DIYer, the size and weight make this impact wrench easy to use for a wide variety of tasks.

Noise Level

The Milwaukee M12 IR-201B operates at a noise level that's quieter than most comparable impact wrenches. At around 80 dB, the noise produced is noticeable but not overly loud or distracting. Users mention the ratcheting noise is more of a rapid clicking rather than a harsh, jarring sound.

Compared to pneumatic impact wrenches that can be over 100 dB, the M12 runs quieter for prolonged use. The lower noise makes it better suited for applications where sound levels need to be kept to a minimum. It could be used for automotive repairs in a home garage without disturbing neighbors for example.

The noise level is comparable to other cordless electric impact wrenches. Brands like DeWalt or Makita produce similar decibel levels in the 80 dB range. So the Milwaukee is on par for a battery powered impact ratchet.

Overall, the M12 IR-201B produces a reasonable noise level. While audible, it's not excessively loud like traditional air impact wrenches. The lower noise output improves the user experience and makes the tool appropriate for noise-sensitive environments.

Accessories

The Milwaukee M12IR-201B impact ratchet comes with a good selection of accessories included in the box. You get two compact M12 2.0Ah lithium-ion batteries, an M12 charger, and a soft bag for storage and transport.

The batteries are Milwaukee's RedLithium batteries that provide longer run times, faster charging, and better performance in extreme temperatures compared to standard lithium-ion batteries. The included charger can fully recharge an empty 2.0Ah battery in around 30 minutes.

Some handy optional accessories you can add on include:

• Extra batteries - It's always good to have spares to extend run time or have one charging while using the other.

• Right angle attachment - Allows you to get into tighter spaces at different angles.

• Extensions - Increase your reach in confined areas. They come in 3" and 6" lengths.

• Sockets - The tool doesn't include any sockets so you'll need to purchase the size drive sockets you need.

Having a few extra batteries, the right angle attachment, and some extension bars can really maximize the versatility of this compact impact ratchet. Just remember that it uses 1/4" hex drive sockets.
