Pros & Cons

DEWALT 20V MAX 5.0Ah Battery (DCB205)

Pros

  • Genuine DEWALT 20V MAX pack backed by DEWALT's 3-year warranty
  • 5.0Ah capacity suits daily-use 20V MAX tools without frequent swaps
  • Drop-in fit across the entire 20V MAX tool lineup

Cons

  • No fuel gauge readout on this pack
  • Costs more upfront than a compact 2.0Ah pack
  • Not compatible with FlexVolt-exclusive 60V tools

RYOBI ONE+ 18V Lithium-Ion Starter High Performance Kit with 2.0 Ah Battery, 4.0 Ah Battery, and Charger

Pros

  • Includes two batteries — a compact 2.0Ah pack and a higher-capacity 4.0Ah pack — plus a charger, all genuine Ryobi
  • Two different pack sizes cover both lightweight/compact use and longer-runtime use from one purchase
  • Good value for a two-battery-plus-charger bundle at under $100

Cons

  • Currently showing low stock on Amazon
  • Because it bundles two different-capacity batteries, we don't collapse that into one capacity number — check the listing for the exact 2.0Ah/4.0Ah split
  • We haven't run our own runtime tests; capacities are Ryobi's stated ratings

Our Verdicts

DEWALT 20V MAX 5.0Ah Battery (DCB205)

The DCB205 is DEWALT's genuine mid-capacity 20V MAX pack — a safe, warranty-backed default for anyone building out a 20V MAX kit.

RYOBI ONE+ 18V Lithium-Ion Starter High Performance Kit with 2.0 Ah Battery, 4.0 Ah Battery, and Charger

A genuine Ryobi kit that pairs a compact 2.0Ah pack with a higher-capacity 4.0Ah pack and one charger — solid value for ONE+ owners who want both a light pack and a runtime pack.
