The Milwaukee M18 REDLITHIUM XC5.0 Extended Capacity Battery delivers up to 2.5X more run-time, 20% more power, and 2X more life than standard 18 volt lithium-ion batteries. This battery features superior pack construction, electronics, and performance to deliver more work per charge and more work over the life of the pack. It features an advanced design, protecting the pack against harsh job-site environments. This protection routes water away from the electronics and out of the battery pack, extends run-time and life by minimizing heat, and prevents pack failures from vibration or drops.  This battery can also operate in extreme cold weather conditions (below O° 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. It also provides full system compatibility with 60+ M18 cordless solutions.
