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 48-59-1808 M12 and M18 12V/18V Lithium-Ion Multi-Voltage Rapid Battery Charger
If you run both M12 and M18 tools, one charger that handles both packs is a real convenience — this is a genuine Milwaukee part at a fair price, though stock availability varies.
