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.

18 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.

3.0 Ah (from the product name)
Battery weight
What this means

Battery weight is the pack on its own, as listed by the maker. Add it to the tool-only weight to estimate the working weight. Higher-capacity packs add weight, which you will notice in overhead and all-day work.

1.33 lb
