DCB122

Pros & Cons

At a Glance

Overview

The DEWALT DCB122 is a genuine 12V MAX 2.0Ah battery — the entry point for DeWalt's compact 12V MAX platform, priced at $34.90. It's built specifically for 12V MAX subcompact tools like small drill/drivers and inspection tools, and it is not interchangeable with DeWalt's more common 20V MAX lineup.

We haven't tested this pack for runtime. This is a compatibility-first guide: what platform it belongs to, what it fits, and where it doesn't.

Who it's for

This pack is for owners of DeWalt's 12V MAX subcompact tools specifically — small drill/drivers, screwdrivers, inspection cameras. If your DeWalt tools are the more common 20V MAX drills, saws, and drivers, this battery will not fit them; you'd need a DCB203 or DCB205 instead.

Compatibility

12V MAX and 20V MAX are separate DeWalt platforms with different battery footprints — they are not interchangeable, despite both being DeWalt. A dual-voltage charger like the DCB1104 can charge both 12V MAX and 20V MAX packs from one unit, but the batteries themselves only work in their own platform's tools. Double-check your tool's model number and battery slot before buying this pack.

Genuine vs. aftermarket 12V packs

This is a genuine DEWALT pack under DEWALT's 3-year warranty. At under $35, the price gap to unbranded 12V MAX-compatible packs is usually small, and the genuine pack's warranty coverage plus matched protection electronics make it the safer default, especially for a platform where fewer aftermarket options exist to compare against.

Buying notes

This is the lowest-priced genuine pack in DeWalt's lineup covered here, which makes sense given 12V MAX tools are lighter-duty by design. 2.0Ah is standard for this platform's compact use case, but don't expect it to hold up on anything beyond light-duty work — that's not what 12V MAX tools are built for.
