Battery platforms
Every cordless tool lives on a battery platform. Pick yours to see exactly which batteries, chargers, and kits fit — and where cross-brand adapters do (and don't) make sense.
Milwaukee
Milwaukee M12
12V MAX (10.8V nominal)
Any M12 battery fits any M12 tool. Higher-capacity XC and High Output packs are physically larger and add runtime but power the same tools; a compact subcompact tool can feel nose-heavy with a 5.0Ah pack.

Milwaukee M18 / M18 FUEL
18V
Every M18 battery fits every M18 and M18 FUEL tool — the platform has stayed backward compatible since 2011. High Output and FORGE packs deliver more current for high-draw tools like grinders and table saws, but they also drop into a basic drill.

DeWalt
DeWalt 20V MAX
20V MAX (18V nominal)
All DeWalt 20V MAX batteries fit all 20V MAX tools. FlexVolt 60V batteries are also backward compatible and run 20V MAX tools by stepping down to 20V, so a FlexVolt pack can serve double duty.

DeWalt FlexVolt (20V/60V MAX)
20V/60V MAX (120V MAX in pairs)
FlexVolt batteries switch voltage automatically: they run 20V MAX tools at 20V and 60V MAX tools at 60V. One FlexVolt pack can cover both systems, and two together power 120V MAX tools.

DeWalt 12V MAX
12V MAX (10.8V nominal)
12V MAX batteries fit all DeWalt 12V MAX subcompact tools. It is a separate footprint from 20V MAX and is not interchangeable with it.

Ryobi
Ryobi ONE+ 18V
18V
Ryobi's headline promise: every ONE+ 18V battery from 2011 on fits every ONE+ tool across 300+ products, and HP High Performance packs add power for demanding tools. Backward and forward compatible within the 18V line.

Ryobi 40V
40V MAX (36V nominal)
All Ryobi 40V batteries fit all Ryobi 40V outdoor tools. Higher-capacity packs add runtime for mowers and blowers that draw hard.
