Milwaukee M18 8.0Ah RED LITHIUM™ Battery: All-Day Power for Heavy-Duty Professional Tasks

Core Performance Breakthroughs​
Ultra-Long All-Day Runtime: 8000mAh (144Wh) capacity fuels extended high-load tasks — use an M18 1/2″ high-torque impact wrench to remove 300+ commercial truck lug nuts, or run an M18 7-1/4″ circular saw through 450+ 2×4 lumber boards on a single charge (33% more cycles than 6.0Ah batteries).​
RED LITHIUM™ Heavy-Duty Advantage: Exclusive lithium-ion chemistry maintains stable 18V output even under extreme loads (e.g., 1,500 in-lbs torque tools), with industry-leading low-temperature performance (-25°C to 50°C) — reliable for winter construction sites, cold garages, or outdoor jobs in harsh weather.​
Rapid Recharge to Cut Downtime: Compatible with Milwaukee M18 fast chargers (e.g., 48-59-1812, 48-59-1828), reaching 80% charge in 40 minutes and full charge in 75 minutes — get back to work fast, even during short breaks.​

Industrial-Grade Durability & Safety​
Job Site-Tough Construction: High-impact polycarbonate shell with reinforced double-wall impact zones withstands 2.0m drop impacts, while a thick chemical-resistant coating repels grease, oil, and solvents (critical for automotive and industrial environments).​
6-Layer Intelligent Protection System: Includes over-charge, over-discharge, over-temperature, short-circuit, cell-balancing, and reverse-polarity protection — extends cycle life to 1200+ charges (20% longer than 6.0Ah models) and prevents damage to both battery and tools.​
IP54 Weather & Dust Resistance: Dust-tight and water-resistant design handles rain, mud, and dusty concrete demolition sites without performance loss, making it ideal for indoor and outdoor professional use.​

Universal M18 Ecosystem Compatibility​
Full M18 Heavy-Duty Tool Integration: Seamlessly powers all Milwaukee M18 cordless tools, including high-torque and large-format models:​
Heavy Impact Tools: 2867-20 (1/2″ high-torque impact wrench), 2854-20 (1/4″ hex high-speed impact driver)​
Saws & Drills: 2830-20 (7-1/4″ circular saw), 2804-20 (1/2″ hammer drill), 2734-20 (18V reciprocating saw)​
Large Outdoor & Specialty Tools: 2828-20 (commercial string trimmer), 2904-20 (concrete grinder), 2840-20 (18V leaf blower)​
Backward Compatibility: Works with all M18 tools manufactured since 2015 — no need to upgrade your existing M18 system, protecting your long-term tool investment.​

User-Centric Design Details​
Precise Runtime Monitoring: 4-LED fuel gauge displays remaining capacity (25%/50%/75%/100%) with a single press, eliminating guesswork about when to recharge (critical for time-sensitive projects with tight deadlines).​
Balanced Ergonomics: Weighs only 1.0kg (still 10% lighter than competing 18V 8.0Ah batteries) with a slim profile (125×80×60mm) — reduces fatigue during overhead drilling, extended wrench use, or all-day tool operation.​
Long-Term Storage Reliability: Holds 85% charge for up to 12 months in storage — ready to use for emergency repairs, last-minute jobs, or seasonal projects without pre-charging.​

Professional-Grade Reliability​
Backed by Milwaukee’s 3-year limited warranty and RED LITHIUM™’s proven track record in industrial settings, this battery is built to withstand daily abuse from professional use. Whether you’re a construction contractor managing large crews, a heavy-duty mechanic servicing commercial vehicles, or a landscaper maintaining sprawling properties, it delivers the 18V power, durability, and runtime to keep your M18 tools working as hard as you do.​
