VARTA HALF AA Battery, half the size of a standard AA battery and double the voltage (3V). The Varta CR1/2AA, or CR14250 uses Lithium Manganese Dioxide chemistry for a high energy density and a wide operating temperature range of -40°C to + 85°C. Self discharge is low at less than 0.5% p/a at 20°C, giving an effective shelf life of 10 years.
