Our take on the DeWalt DCB122 12V MAX 2Ah Lithium-Ion Battery

The DCB122 is DeWalt's 12V MAX lithium-ion battery pack rated at 2.0Ah, the mid-capacity option in the 12V MAX line. It carries a built-in LED fuel gauge so you can check charge before a job, and it fits every DeWalt 12V MAX tool and the brand's 12V chargers. It offers over 50% more capacity than the older DCB120, so it runs longer in the same tools. It suits owners of DeWalt 12V MAX drills, drivers and oscillating tools who want a spare or a step up from the 1.3Ah pack; the trade-off is that it is heavier and larger than the smallest pack and holds less charge than the 3.0Ah version.
