Charging Technology: Rapid Optimum Charger communicates with the battery's built-in chip to optimize battery life by actively controlling current, voltage and temperature, and has a built-in fan to cool the battery to produce more lifetime work.
More Work: LXT Lithium-Ion batteries and Rapid Optimum Chargers produce 430% total lifetime work with 2.5x more cycles than Ni-Cd batteries.
Faster Charging: 18V LXT Lithium-Ion Batteries charge in 30 minutes. 18V Compact Lithium-Ion Batteries charge in 15 minutes, 4X Faster than Ni-Cd batteries.
Less Weight: LXT Lithium-Ion Batteries weigh 40% less than Ni-Cd.
