Our Verdicts
DEWALT 12V MAX 2.0Ah Battery (DCB122)
The DCB122 is the genuine, budget-friendly entry point for DEWALT's 12V MAX platform — right-sized for compact tools, not a fit for the 20V MAX lineup.
Milwaukee M12 REDLITHIUM 2.0Ah Battery (2-Pack) & Charger Kit
A genuine Milwaukee M12 two-battery-and-charger kit is the straightforward, warranty-backed way to get started or restock on the M12 platform — not the highest capacity, but the safest default.
