The battery pack is slid on the charger to hold it firmly during charging. Modern electronics " control it all ". Indicators (visible and audio) let you know about temperature, remaining charging time or any battery failure.

Most cordless drill kits ( Dewalt, Makita, Bosch, Ryobi, Porter-Cable, Hitachi, Rigid) come with 1 hour - chargers as standard equipment on most models. With the increasing popularity of Lithium-Ion batteries some manufacturers (e.g. Makita) are now even supplying 15-min high-speed battery chargers as standard equipment on some models.

Advanced Chargers, especially the new generation of Li-Ion battery chargers do also have:

  • Cooling Fan - driving air through the battery during the charging process
