DeWalt battery 18V 3.5Ah Powerstack - 2pcs

DeWalt 18V XR Powerstack 3.5 Ah battery set, which includes two battery packs.

DEWALT POWERSTACK™ batteries use stacked battery cells instead of traditional cylindrical cells
Stacking technology offers innovations that take wireless work to a new professional level
POWERSTACK™ batteries offer more power with less weight and more compact dimensions

Unlike standard cylindrical cells, flat pocket cells ensure significantly lower internal resistance, allowing the tool to draw more current under heavy load.

The battery lasts up to twice as many charge cycles as the traditional DeWalt 5.0 Ah (DCB184) or 2.0 Ah cylindrical model.

Lower resistance means less heat is generated under load, protecting the battery from overheating.

The design is lighter and more ergonomic than conventional batteries, making the tool more comfortable to handle.
