Battery type The type of batteries provided with the drill. All are rechargeable. The more common type is denoted NiCd, for its nickel-cadmium components. Nickel-metal hydride (NiMH) batteries boast added energy for their weight. Lithium-ion (Li-Ion) batteries are the latest type and deliver even more power in a smaller size. Lithium-ion and NiMH batteries can be disposed of with regular refuse; NiCd must be recycled.

Battery recharge time (in minutes) The time it takes to completely recharge a battery after it has properly cooled down. Most of the fast chargers have a built-in temperature sensor that delays the charging cycle when the battery is too hot from recent heavy use until the battery has cooled.

Speed ranges Many cordless drills have two separate speed ranges, or gear ratios; some newer models have three. The slower speed range peaks at about 400 revolutions per minute (rpm) and provides increased torque (twisting force) for driving large screws. A higher speed range that reaches about 1,500 rpm or more, is well suited for rapid drilling. Lower-priced drills usually have a single speed range that tops out at approximately 600 to 800 rpm, compromising both driving and drilling performance.
