Milwaukee 48-11-1835D M18 REDLITHIUM High Output CP3.0 Battery

Milwaukee’s 48-11-1835D M18 REDLITHIUM HIGH OUTPUT CP3.0 is a compact 18V lithium-ion battery that lets smaller M18 tools work harder without the weight of an XC or HD pack. Using HIGH OUTPUT cell technology and REDLINK™ Intelligence, this 3.0Ah pack delivers 50% more power and runs 50% cooler than standard M18 CP batteries. In real jobs, that means an impact driver keeps its speed deeper into the drive, a compact grinder holds wheel RPM longer, and a hackzall makes more cuts before you notice slowdown. Because it stays cooler during back-to-back tasks, the pack sustains performance across heavier applications instead of throttling early. You also get fade-free power, so the tool feels consistent through most of the discharge window rather than tapering off at half charge. A durable pack housing helps resist jobsite abuse, while the onboard fuel gauge lets you plan swaps before a pack goes flat. Best of all, the CP3.0 keeps tools nimble overhead and in tight spaces, yet provides XC-class power that used to require a bigger, heavier battery. Fully compatible with 200+ M18 tools and all M18 chargers, this is the everyday “carry” pack that meaningfully upgrades performance without changing your setup.

Markets

• Framing & Carpentry Keeps drivers, trim routers, and compact circular saws moving without the weight of larger packs.
• Electrical & HVAC Reliable power for anchors, hole saws, and panel work; compact form improves access in tight runs.
• Automotive & Fleet Longer, cooler runs on right-angle impacts, compact grinders, and lights during bay work.
• Metal Fabrication & MRO Sustains RPM on cut-off and deburring tasks with a lighter, better-balanced tool.
• Concrete & Masonry Pairs well with SDS-Plus rotary hammers for anchors and fixtures where agility matters.
• Facility & Property Maintenance Standardizes a light, high-output pack across mixed M18 kits for day-to-day service.

If standard CP packs leave your tools sagging under load—or XC packs make them feel bulky—the HIGH OUTPUT CP3.0 hits the sweet spot. You’ll feel a real bump in torque and sustained RPM on compact M18 tools, plus cooler operation that carries you through long fastener runs and back-to-back cuts. REDLINK manages temperature and current to protect both battery and tool, while fade-free delivery keeps performance steady until it’s time to swap. Because it’s still a compact pack, balance and reach stay excellent for overhead work, cabinet installs, and ladder jobs. With full M18 compatibility and a 60-minute typical charge time (charger dependent), the CP3.0 is the simplest way to gain power and runtime across your kit without adding weight or changing platforms.

Why Customers Choose the Milwaukee M18 REDLITHIUM High Output CP3.0 Battery

Crews choose the CP3.0 because it delivers real power gains in a light, compact pack. The 50% more power keeps compact drills, impacts, and saws on pace in hardwood, metal, and masonry, while 50% cooler operation sustains performance across repeated cuts and long fastener sequences. REDLINK™ protection reduces downtime from overloads, and the fuel gauge helps manage rotations efficiently. Since the pack fits 200+ M18 tools, a single purchase lifts performance across an entire fleet—drivers, lights, cut-off tools, and more—without the weight penalty of larger batteries. For daily carry where balance, access, and control matter, the REDLITHIUM HIGH OUTPUT CP3.0 is the practical upgrade that keeps work moving with fewer swaps and steadier speed.
