Lithium cordless tools are equipped with lithium-ion batteries, which are known for their high energy density, lightweight design, and fast charging capabilities. Compared to traditional nickel-cadmium batteries, lithium-ion batteries provide a longer runtime and faster recharge times, making them ideal for professionals and DIY enthusiasts who require reliable power on the go.

One key advantage of lithium-ion batteries in cordless tools is their ability to maintain a consistent power output throughout the discharge cycle. This means that users can experience consistent performance from their tools without experiencing a drop in power as the battery depletes. Additionally, lithium-ion batteries have a low self-discharge rate, allowing them to hold their charge for extended periods when not in use.
