(1) Nominal voltage: Nickel-cadmium alkaline batteries used to identify the type of appropriate voltage approximation. Nickel-cadmium alkaline battery single battery nominal voltage of 1.2V. (2) Open circuit voltage: the battery open circuit condition, the positive, the potential difference between the anode. (3) termination voltage: battery voltage discharge at the end. (4) the float voltage: voltage to keep the battery fully charged state of need. (5) Rated capacity: at 20 ℃ to 5h-rate discharge termination voltage to the battery 1. When OV, can provide power. (6) opening Battery: battery cover with a hole, an exhaust means may be installed, allowing the escape of gaseous products of a secondary battery (rechargeable battery can be repeatedly). (7) A sealed battery: In the standard specified by the manufacturer of the charging system and temperature conditions, the electrolysis products in the internal battery by some or all of the gas recombination sealed achieved, when the internal pressure exceeds a predetermined value, allowing the gas to be reset by a or can not reset the pressure relief device to escape. This battery during use, no need to add electrolyte, is a low maintenance battery. At present, China's production of various types of nickel-cadmium alkaline batteries are generally cylindrical sealed battery. (8) bag nickel-cadmium alkaline batteries (opening organic plate cassette nickel-cadmium batteries): The active substance is wrapped in a closed bag flat perforated steel, the positive and negative electrodes are separated by partitions, and installed in plastic housing made of nickel-plated steel or inside. Bag used for the battery, battery low magnification. For more information, please click http://www.hndhdq.com.cn/-----------------zhongqi
