Milwaukee M18B5 M18 REDLITHIUM-ION 5.0Ah Battery
Available in stock (149)
The M18 workhorse pack. The Milwaukee M18B5 is a 5.0Ah REDLITHIUM-ION battery built on a durable metal frame with shock responsive separators, which prevent pack failure from excessive vibration or drops — the difference between a battery that survives a fall off a scaffold board and one that doesn't.
REDLITHIUM-ION chemistry delivers up to 2.5 times more run time, up to 20% more power and up to twice the battery life compared with other lithium-ion technologies and previous Milwaukee battery technology. Water protection routes water away from the electronics and out of the pack, and it will work down to −20°C without compromising run time or battery life.
