Industry-Leading REDLITHIUM™ Technology 

Each Milwaukee battery M18 is engineered with REDLITHIUM technology, featuring advanced cell construction, overload protection, and intelligent thermal management. Compared to standard lithium-ion batteries, the Milwaukee M18 REDLITHIUM battery runs cooler, lasts longer, and performs more consistently in extreme conditions.

Need a longer runtime? The Milwaukee M18 6.0 Ah battery delivers extended endurance for high-demand applications, while the Milwaukee M18 5.0 Ah battery offers a perfect blend of weight and runtime for everyday use. Whether you're working in freezing cold or sweltering heat, these batteries maintain power output with no power drop-off. The proprietary cell design features reinforced construction and specialized electronics that protect against jobsite hazards including water, dust, and drops that would typically damage conventional batteries.

Milwaukee System Compatibility That Works Harder

Milwaukee batteries M18 are fully compatible across the M18 platform, including the premium Milwaukee FORGE™ battery lineup with even greater output in extreme-use tools. For lighter-duty tasks, the compact Milwaukee M12™ battery provides seamless support, giving professionals total flexibility across the jobsite. 

Built-in overload protection, temperature control, and water resistance make the Milwaukee M18 battery significantly more resilient on the jobsite. The best Milwaukee M18 battery models are designed for long-term performance—even under constant use. Each Milwaukee M18 battery is backed by a limited warranty, offering added confidence and support for long-term professional use.
