Our take on the DeWALT 12V MAX Lithium Ion 3.0Ah Battery (DCB124)

The DeWalt DCB124 is a 12V MAX lithium-ion battery pack with 3.0Ah capacity, built for DeWalt's XTREME 12V cordless tools. It doubles the runtime of the standard 1.5Ah pack and adds a built-in LED fuel gauge so you can check charge before starting a task. It suits owners of DeWalt 12V drills, drivers and oscillating tools who want longer runs between charges. Against smaller 12V packs it trades a little extra weight and bulk for noticeably more work per charge; owners rate it highly for reliability and fit.

About the DeWALT 12V MAX Lithium Ion 3.0Ah Battery (DCB124)

The DEWALT DCB124 is a compact lithium-ion battery pack for DEWALT XTREME 12V MAX cordless tools. It has a 3.0 amp-hour capacity for longer work between charges.

A built-in 3-LED fuel gauge shows the remaining charge when you press it, so you can check the battery before starting the next task.

It works with DEWALT XTREME 12V MAX tools and DEWALT 12V MAX chargers, so it can serve as a replacement or a spare for tools you already own. The compact size suits tight-space work. This is a battery only, not a starter kit, and a compatible DEWALT 12V MAX charger is needed if you don't already have one.
