Powerstack batteries provide more power through higher currents and higher voltage. The increase in connected surface area allows for higher currents to flow through the battery and the pouch cells have lower internal resistance making more power available to the tool. A low impedance construction converts into much higher max watts out for a greater range of applications. Superior thermal performance versus cylindrical cells means for increased battery durability and so increased cycle life for greater return on investment. Improved user comfort due to the more compact design and lighter weight compared to that of other 18v batteries on the market. Features & Benefits • New Powerstack battery technology • Low impedance construction increases power • Up to 50% more power for improved productivity (application speed vs. DCB183) • Superior thermal performance versus cylindrical cells, thus increasing recharge cycles • Twice the lifetime of a cylindrical battery (charge cycles vs. DCB183)
