Platform comparison
DeWalt 20V Max vs Milwaukee M18 vs Makita 18V vs Ryobi One+: choosing your battery ecosystem
Battery interoperability, Ah run-time math, brushless vs brushed efficiency, and the bare-tool vs combo-kit calculus. The numbers that actually determine whether you're locked in or well-equipped.
Why this page exists
Power tool content online splits into two categories: affiliate round-ups that rank every tool five stars, and brand forums where loyalty is the only currency. Neither does the actual battery math for you.
A 5Ah DeWalt battery and a 5Ah Milwaukee battery both deliver nominally the same energy — but platform depth, brushless motor spread, and price-per-tool differ enough to matter over the life of a shop. This page explains those differences plainly.
Plain note about money. Links below go to eBay searches with an affiliate tag. If you buy through one, a small commission comes to this site. Your price is identical either way. The searches are ones we'd actually run — not sponsored placements.

DeWalt 20V Max combo kit
DeWalt's 20V Max platform spans 200+ tools. Combo kits (drill + impact driver + batteries + bag) offer the best per-tool entry cost and are a natural first step into the ecosystem.
Milwaukee M18 Fuel cordless drill
Milwaukee's M18 Fuel line uses POWERSTATE brushless motors, REDLINK PLUS intelligence, and REDLITHIUM batteries. The drill/driver is typically the platform anchor tool.
Makita 18V LXT brushless
Makita's LXT platform has 300+ compatible tools — the deepest ecosystem by tool count. Star Protection Computer Controls coordinate tool and battery communication for optimized performance.
Ryobi One+ battery 6Ah
Ryobi's 18V One+ platform is the value leader, with 300+ tools at lower per-tool prices. The 6Ah battery (PCK006) delivers meaningful run-time improvement over the included 1.5Ah starter batteries.
Bosch 18V brushless cordless
Bosch's 18V CORE18V platform competes on precision and build quality. Strong in European professional markets; smaller North American tool count than DeWalt/Milwaukee but excellent ergonomics.
