The capacity of a cordless drill battery, measured in ampere-hours (Ah), indicates how much charge the battery can hold. I’ve noticed that higher Ah ratings translate to longer run times before recharging is needed. Voltage (V) determines the power of the drill; higher voltage means more power, making the drill capable of tougher tasks. Commonly, drill batteries range from 12V for light-duty tasks to 18V or 20V for more demanding work.

Battery Life and Longevity

Battery life and longevity are critical considerations. Battery lifespan refers to the number of charge cycles a battery can undergo before it starts losing its ability to hold a charge. Proper care can prolong battery life—proper storage and regular use prevent capacity loss. From my experience, Lithium-ion batteries typically offer the best longevity and can last for several years with appropriate maintenance.

Charging Basics

When I charge my drill battery, I make sure to adhere to precise methods to maintain its lifespan and efficiency. Proper charging practices are essential, and knowing the risks of overcharging is equally important.
