Contactless Recharging - The DWZ-M70 system can operate using conventional AA size Alkaline batteries. This system also supports use with NiMH AA size rechargable batteries along with use of the (optional) BC-DWZ1 battery charger. The BC-DWZ1 is a contactless recharger, this means you simply place the transmitter into the charging station to recharge NiMH-type batteries. You do not need to physically remove the batteries to recharge them, which saves you time and reduces wear and tear to the transmitters.
