About Product Overview

The M18 CP3.0 HO is Milwaukee's compact battery built with High Output technology, giving M18 tools more power, more speed, and more runtime than standard CP batteries without adding bulk. It's the same footprint hardware users expect from the compact line, but with RedLithium cells engineered to deliver more consistent power under heavy load - useful whether you're running a drill/driver on a framing job or an impact wrench in a truck bay.

Because it works across most M18 tools, this battery is a practical add to any kit where you're swapping between drills, saws, and lights throughout the day. The built-in charge indicator light lets you check charge status at a glance, and the RedLithium chemistry is rated to keep working in temperatures as low as -20 degrees, so cold garages and job sites in winter aren't a problem.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
