Specifications

Voltage
What this means

Voltage identifies the battery platform. Some makers quote a peak (max) figure at the start of discharge while others quote nominal, so 18 V nominal and 20 V max packs usually have the same cell count. Higher-voltage platforms typically serve more demanding tools. Batteries only fit tools from the matching line.

20 V
Battery capacity (each)
What this means

Amp-hours (Ah) is the battery's charge capacity. At the same voltage, a higher Ah pack runs longer between charges but is usually larger and heavier. Smaller packs keep the tool lighter for overhead and light work; larger packs suit saws, grinders and other high-draw tools.

4.0 Ah
