With the rapid development of semiconductor integrated circuits, nickel-cadmium alkaline batteries into too quickly into our lives. And nickel-cadmium alkaline batteries in our lives and applications are increasingly widespread and popular in various sectors of life. While nickel-cadmium alkaline batteries portable, easy to use. Nickel-cadmium alkaline batteries are characterized by stable discharge voltage, long life pressure charge, can be recharged and require little maintenance. Although the one-time investment is large, but compared with zinc-manganese batteries, but cost is high, due to nickel-cadmium alkaline battery charging times can be up to a thousand times, to make nickel-cadmium rechargeable alkaline battery cell to restore its ability to work. For this reason, a good grasp of basic nickel-cadmium battery charging method is very necessary. For portable electric appliances in cycle use nickel-cadmium alkaline batteries should be charging and fast charging standard; for AC power supply, and as a backup power supply nickel-cadmium alkaline batteries should be used to trickle charge when the rechargeable battery that is isolated from the load ; or the use of float charging, i.e. when the rechargeable battery hooked up with loads. Nickel-cadmium alkaline storage battery charging method divided two kinds of constant current charging and constant voltage charging, constant current charging method is beneficial because of the charging time and battery life, and therefore a sealed nickel-cadmium alkaline storage battery is often used constant current charging method.
