The 48-11-2401 is smaller and lighter than NiCd compact batteries, yet delivers long runtime and fade-free power.

This battery is 65% lighter and 50% smaller than compact NiCd batteries and offers 1.5 amp-hours of runtime. With built-in Milwaukee durability, it runs cooler and performs in climates below 0°F/-18°C. Managed by Milwaukee's exclusive REDLINK Intelligence, the battery features overload protection to prevent you from damaging your cordless power tools in heavy-duty situations, while the discharge protection prevents cell damage. The temperature management system and individual cell monitoring help maximize battery life. Use this durable battery to power your Milwaukee M12 cordless power tools.

The 48-59-2401 Quickly charges all M12 batteries. Power up your M12 RED LITHIUM and M12 Lithium-Ion batteries in less than an hour with the Milwaukee 48-59-2401 M12 Lithium-Ion 30 Minute Battery Charger. It communicates directly with the battery pack to manage charges and features an easy-to-load design. The charger's slim profile requires little bench-top room, while the pass-through plug conserves valuable outlet space.
