Specifications

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.

9.0 Ah
Energy
What this means

Watt-hours (Wh) is the total energy stored, roughly voltage times amp-hours. It is the fairest way to compare packs of different voltage. Watt-hours also matter for shipping and air travel: airlines limit lithium-ion batteries, and packs over 100 Wh generally need airline approval.

180 Wh
