The camera‘s electronics and motors are supplied with power by a rechargeable sintered high-
performance Nicad battery. The benefits of this professional solution are high shooting capacity, easy handling and safe operation even at low temperatures. At standard room temperature, the energy of the dedicated battery is good for about 200-250 shots. When only about 20 exposures remain, a warning will light up in the camera viewfinder (6008AF and 6008I2 only). Interchangeable batteries will see you through even extensive shoots.
Rolleiflex 6000 cameras come with a rapid charger with automatic charge limiter. It takes about one hour to recharge the battery. The charger will then switch back from rapid to normal charging. In a hurry, you may stop charging after only 15 minutes. The battery will then provide sufficient energy for about 50-100 shots. If there is no wall outlet around, the charger may be connected to a 12V car battery via an optional cable.
