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 [2]
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.

2.0 Ah [2]
Works with (maker's statement)
What this means

This is the maker's own compatibility statement. Some batteries fit older or newer tools in the same line, sometimes with limits on features or performance. Third-party adapters are not covered by the maker and may affect warranty and safety. Check the maker's current list when in doubt.

Charge indicator
What this means

A charge indicator shows remaining charge, usually as a row of LEDs on the pack or charger. It is a rough guide, not an exact percentage, and readings can shift once the battery rests or cools. Some chargers also show fault or temperature status.
