M18™Redlithium High Demand™ - Milwaukee Electric Tools

The M18? REDLITHIUM? HIGH DEMAND? 9.0 Battery Pack delivers
up to 5X more run-time, 35% more power, and runs 60% cooler
than standard 18V lithium-ion batteries. The battery is
best optimized for high draw products and sustained run-time
applications, and it provides the next, large step towards
full corded replacement when paired with the M18 system of
solutions. It maintains full power and runs substantially
cooler through heavy applications, allowing users to push
their cordless tools harder and longer than ever before.
The M18? REDLITHIUM? HIGH DEMAND? 9.0 battery is fully
compatible with 100+ M18? tools.
