MAXIMIZING DUTY CYCLES WITH ADVANCED XR LITHIUM-ION ARCHITECTUREProfessional tool users understand that runtime isn't just about convenience; it's about minimizing downtime between charges to maintain a high workflow cadence. The DCB205 5.0Ah battery pack utilizes high-quality lithium-ion cells that provide a significant 60% increase in capacity compared to standard packs, without a substantial increase in weight or footprint. This balance of power density and ergonomics is critical for high-draw applications like circular saws or SDS Plus rotary hammers where sustained torque is required. The integrated 3-LED fuel gauge allows for precise power management, ensuring you never climb a ladder with a near-depleted pack. Engineered with no memory effect and virtually no self-discharge, these cells maintain their peak performance through hundreds of charge cycles, providing a superior return on investment for any professional fleet. / Premium 5.0Ah capacity provides up to 60% more runtime than standard 20V MAX* battery packs. / Integrated 3-LED Fuel Gauge system allows for immediate feedback on the state of charge. / Lightweight 1.4 lb design offers maximum runtime while minimizing user fatigue during overhead use. / No memory effect and virtually no self-discharge ensures the tool is ready for work even after storage. / Fully compatible with the entire DEWALT 20V MAX* line of tools and chargers.
