Cordless tool batteries and power accessories keep tools powered and make connections to different power sources and devices. Cordless tool batteries provide power to cordless tools. They are used to equip bare tools with a battery, change to a different battery series, or replace batteries that are damaged or no longer hold a charge. Cordless tool battery chargers replenish the power of depleted tool batteries so that the batteries can be reused. Cordless tool power adapters and accessories modify how tool batteries are used or how tools connect to batteries or other power sources. Cordless tool battery-powered inverter generators convert DC battery power to AC power for running corded power tools, appliances, and other electrical-powered devices where a wired power source is unavailable.
