NOT ALL LITHIUM-ION BATTERIES ARE CREATED EQUAL. 

Milwaukee REDLITHIUM™ batteries last longer, think faster and work harder than all other professional lithium-ion batteries. The exclusive integration of chemistry, pack design and circuitry come together to deliver superior output in the harshest of environments. REDLITHIUM™ batteries let you deliver more work over the course of your day and over life of the battery.

THE M18™ REDLITHIUM™ HIGH OUTPUT™  DIFFERENCE

“Standard” batteries are built with 18650 cells, 18mm diameter, 65mm length,  whereas the High Output batteries are built with larger 21700 cells, 21mm diameter, 70mm length. With the HIGH Output Battery pack you can expect it to give you 50% more power and run 50% cooler, when compared with the other M18 REDLITHIUM-ION battery packs.  Milwaukee’s High Output battery packs also have higher charge capacities, delivering longer runtime.

With 40%* more Lithium, Milwaukee’s High Output battery packs really do pack more punch than “standard” batteries.
