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.

5.0 Ah
Charger in box
What this means

This states whether a charger is included and which type. Chargers vary in output, so the same battery can take noticeably different times to charge on different chargers. Tool-only listings usually include no charger.

Yes
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
Warranty
What this means

This is the maker's published warranty term. Terms for tools, batteries and chargers often differ, and some depend on registration or exclude certain uses. Read the maker's terms for what is covered, how claims are handled and whether proof of purchase is required.

3 Year Limited Warranty
Kit weight (maker's figure)1.6 lb
Battery line
What this means

Battery line is the maker's platform name, which determines which tools and chargers the pack fits. Makers generally keep one battery design across a platform, but batteries from different makers are not interchangeable. Buying into a line is often a longer-term choice than buying a single tool.

REDLITHIUM HIGH OUTPUT
Dimensions (L x W x H)4.8 x 3.1 x 3 in
