The EGO 56V 12.0Ah ARC Lithium™ Battery uses industry-leading technology to deliver Power Beyond Belief™. Its patented ARC Lithium™ design keeps the battery from overheating by pushing heat away so your equipment runs longer at full power. Its durable, shock-resistant design protects batteries from drops and the elements. Intelligent power management monitors and optimizes each individual battery cell to maximize power, performance, and runtime. This 12.0Ah battery features a fuel gauge with built-in indicator lights that show how much runtime is remaining in 20 percent increments. The 12.0Ah battery fully charges in 75 minutes with the EGO POWER+ Turbo Charger (CH7000), 90 minutes with the Rapid Charger (CH5500), 160 minutes with the 320W Charger (CH3200), and 230 minutes with the Standard Charger (CH2100). Two 12.0Ah batteries will fully charge in 180 minutes with the EGO Power+ Dual-Port Charger (CH2800D). With the industry’s most advanced battery technology, every EGO tool delivers or exceeds the power and performance of gas without the noise, fuss, or fumes.
