Milwaukee M18™ REDLITHIUM™ XC5.0 Extended Capacity Battery Pack 48-11-1850

Milwaukee's M18™ REDLITHIUM™ XC5.0 Battery provides up to 2.5X more runtime, 20% more power, and 2X more recharges compared to standard lithium-ion batteries. Designed with advanced pack construction, electronics, and performance, this battery helps deliver more work per charge and over the overall life of the pack. It also offers 5.0 amp-hours of runtime, making it ideal for demanding applications.

Built for tough jobsite conditions, each battery runs cooler and performs reliably in extreme environments, including temperatures below 0°F (-18°C). The durable design helps channel water away from internal electronics, reduces heat buildup, and protects against damage caused by vibration or drops.

Featuring REDLINK™ Intelligence, the battery is equipped with overload protection to help prevent damage to your cordless tools during heavy-duty use. Discharge protection also helps guard against cell damage. An integrated temperature management system, along with individual cell monitoring, works to extend battery life and maintain consistent performance.

Upgrade to the REDLITHIUM™ XC5.0 Battery Pack for enhanced runtime, durability, and performance across Milwaukee's M18™ cordless tool system.
