DeWalt advises recharging tool batteries before they run empty

DeWalt advises users to stop using a tool battery when they notice a substantial drop in power, saying a complete discharge may damage it. The article recommends recharging packs at around 20% to 30% rather than running them empty.

DeWalt packs include power cells and a circuit board that controls how they deliver power. The article says drawing power when nearly empty can put extra strain on components and may shorten the pack’s life.
