Alternatively, a 1Ah battery can produce 10 amps of energy, but can only do so for 6 minutes. A 1Ah battery can produce 1 amp of energy per 1 hour of time. The battery life for a cordless ratchet is measured using milliamp hours (mAh) for small batteries or amp hours (Ah) for larger batteries, with 1,000mAh equaling 1Ah. Tools with brushless motors typically cost more.
This extends the life of the motor, increases its overall efficiency, and makes it quieter.
Brushless motors use a type of encoder device to achieve the same result without the wear and tear caused by physical brushes. However, tools with these motors are more affordably priced, making them a good option for casual use. 
This physical contact causes their efficiency to fall to about 75 to 80 percent when compared to the 85 to 90 percent efficiency of a brushless motor.
Brushed motors use brushes inside the motor to deliver electrical current to the motor windings. Whether a cordless ratchet has a brushed or brushless motor can affect the price and efficiency of the tool. A faster speed allows users to loosen or tighten bolts and fasteners quickly, but it can also lead to overtightening if users aren’t careful. The speed of a cordless ratchet is measured in revolutions per minute (rpm), with an average ratchet producing between 250 and 400 rpm. The average torque of a cordless ratchet ranges from 25 to 50 ft-lbs, and the more powerful models work best for automotive tasks. Torque refers to the rotational force produced by a cordless ratchet and is measured in foot-pounds (ft-lbs). The power of a cordless ratchet motor is measured by its torque output and speed. Cordless ratchets range in weight from just under 1 pound to 3 pounds, and while most can fit inside a variety of tool boxes, they can be too heavy for tool belts. Keep in mind that the size and weight of a cordless ratchet typically correlate to power output, with smaller models having less power. The ratchet should have a narrow head and a slim body so that a user can comfortably maneuver the tool around and through obstacles and enable work in tight areas. A lightweight cordless ratchet can help avoid this common problem. However, even a difference of 1 or 2 pounds can increase the likelihood and severity of common hand fatigue symptoms like hand cramps. Most cordless ratchets are light enough for one-hand use. These characteristics include size, weight, power output, and battery life, among other factors.

To help shoppers pick out the best cordless ratchet, we performed hands-on testing with the following models. Many offer safety features that can extend the life of the tool while keeping the user safe. The best cordless ratchet for a home tool kit will depend on its power output, size, weight, battery, and grip. More than just a time-saving tool, a cordless ratchet allows a DIYer to work in tight spaces without having to worry about a ratchet handle’s swing clearance. These tools use a battery to power the motor, which in turn rotates the head of the ratchet. #Snap on ratchet wrench set manual#
Cordless ratchets allow users to work on their vehicles or homes without putting in the effort to operate a manual ratchet and without the risk of tripping on an air hose.
