M18™ 18-Volt Batteries

Milwaukee M18™ 18-Volt REDLITHIUM™-ION batteries incorporate high power cells, REDLINK™ intelligence and best-in-class pack construction to deliver a battery which runs for longer and enhances tool performance unlike any other battery. Compared to previous Milwaukee batteries the M18™ range provides up to 20% more power, 2x longer battery life and 2.5x more run-time. The highly advanced pack construction allows each battery to withstand impact and jobsite conditions and lets the user use the batteries in extreme temperatures down to -20°C.

The M18™ battery range is also home to Milwaukee HIGH OUTPUT™ REDLITHIUM™-ION batteries which include larger cells and a new high power processor to allow the battery to run up to 50% cooler while outputting 50% more power and providing the user with 33% more runtime than standard M18™ batteries.

Don't settle for anything less than the best when it comes to purchasing 18-Volt li-ion batteries for your Milwaukee tools.

18-Volt lithium-ion batteries with an amp-hour rating above 5.0Ah cannot be purchased online due to current shipping regulations. Purchase of said batteries must be made in-store at our Peterborough trade counter. This currently applies only to the M18B9 9.0Ah Battery, M18HB8 HIGH OUTPUT™ 8.0Ah Battery and M18HB12 HIGH OUTPUT™ 12.0Ah Battery. Thank you for your understanding.
