1.2V 1400mAh A NiCd Battery is excellent quality and provides constant power electric current for your power-hungry devices and some solar lights and solar applications. Also, have low internal resistance, ideal for rapid high current discharge, Excellent battery cycle life: 1000 times, Ni-Cad battery can be charged and discharged for up to 1000 times, Environmentally Friendly (Ni-Cad can be recycled), If use once a day, Ni-Cad batteries can last up to 3 years. It is a good practice to do deep-discharge or complete discharge at least once 4 to 8 weeks. Deep discharge ( complete discharge ) is important for Ni-Cad not to develop memory effects. Compared with other types of rechargeable cells, Ni-Cad batteries offer good cycle life and performance at low temperatures with a fair capacity but its significant advantage is the ability to deliver practically its full rated capacity at high discharge rates (discharging in one hour or less).
