Dual 12V HIGH OUTPUT battery pack configuration for increased power delivery and runtime flexibility
The Milwaukee M12 HB2.5 HIGH OUTPUT 2.5Ah battery pack is engineered to deliver increased current output and improved thermal performance compared to standard M12 REDLITHIUM battery packs. This twin pack configuration is designed for professional users operating high-demand M12 FUEL tools where consistent power delivery and reduced downtime are critical.
HIGH OUTPUT technology provides up to 25% more power and runs up to 25% cooler in heavy applications, improving tool performance and minimising thermal stress. REDLINK electronic intelligence with individual cell monitoring optimises runtime and enhances long-term durability. The reinforced housing is resistant to oils, solvents and greases, and the integrated welded frame construction with shock-responsive separators improves resistance to vibration and impact. The battery can operate in extreme temperatures down to -20°C without compromising runtime or service life.
