Featuring electronic coding for tools and chargers, high power contacts with silver coating, capacity indicator with 3 LEDs, red Cool Pack housing constructed of heat conductive material, in-built temperature sensor, large ergonomic release button for ease of use, robust housing and slide-in interface.

Efficient Bosch cooling technology in and around the battery prevents heat damage, gives up to 65 percent longer run-time and up to 100 percent longer lifetime. 4.0Ah Cool Pack cells have finer 'windings' than 3.0Ah allowing more power density in the same pack size with less electrical resistance, making it more efficient.

This means less frequent battery charges and 4.0Ah batteries are fully charged in just 45 minutes.

These Coolpack battery is also the most light and compact battery on the market 600g.
