Pros & Cons
DEWALT 12V MAX 2.0Ah Battery (DCB122)
Pros
- Genuine DEWALT pack backed by DEWALT's 3-year warranty
- Compact 2.0Ah size fits DEWALT's 12V MAX lineup of light-duty tools
- Lowest price point of any genuine pack in this lineup
Cons
- Only compatible with 12V MAX tools, not 20V MAX or FlexVolt
- Limited runtime for anything beyond light-duty use
- No fuel gauge on this pack
Milwaukee 48-59-1850 M18 XC 5.0 Starter Kit
Pros
- Bundles a genuine Milwaukee M18 XC 5.0Ah battery with a charger in one kit
- 5.0Ah capacity gives meaningfully more runtime than Milwaukee's compact 2.0Ah/3.0Ah packs
- Genuine Milwaukee OEM, not a third-party bundle
- Good starter option if you're buying into M18 for the first time or need a spare battery-and-charger set
Cons
- Only includes one battery — no second pack for hot-swapping
- 5.0Ah packs are larger and heavier than compact packs, which can make lighter tools feel nose-heavy
- We haven't run a runtime test ourselves; 5.0Ah is the manufacturer's stated capacity
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 48-59-1850 M18 XC 5.0 Starter Kit
A solid way to add a genuine, higher-capacity M18 battery and charger in one purchase — good value if you need more runtime than a starter 2.0Ah kit provides.
