Dewalt Powerstack DCB1102E2 18 Volt Battery Kit (1.7 Ah, Innovative Pouch Cell Technology, Can be Used in All 18 V XR Battery Machines, with Capacity Display via LEDs, Includes 2 Batteries & Charger)

Dewalt Powerstack battery technology - so you are more productive than ever before.
Because the POWERSTACK batteries provide 50%* more power by maintaining both a higher voltage and a higher current under load. By using pouch cells that have lower internal resistance, POWERSTACK batteries provide more power. At the same time, the application time is also extended by 50%** per charge. How is this possible? Due to their lower resistance, pouch cells stay cooler in use. Thanks to their larger surface, they also dissipate heat better than round cells. Lower heat generation means fewer battery overheating shutdowns and less downtime. At the same time, the Dewalt Powerstack batteries have a 2x longer service life. By charging and discharging batteries, their useful capacity gradually decreases. At the same time, the internal resistance of the cell increases, resulting in higher heat generation and thus less available power to operate your tools. With the Li-Ion pouch cells used in POWERSTACK batteries, the capacity loss is only a fraction as high as conventional round cells. *vs. Dewalt battery DCB8184 (18 Volt/5Ah). ** Usable energy vs. Dewalt DCB8184 Battery (18 Volt/5Ah). *** Charging cycles vs. Dewalt battery DCB8184 (18 Volt/5Ah).
