The nickel-cadmium is a rechargeable battery that uses a nickel oxide hydroxide and metallic cadmium as electrodes. Most of these batteries from China rechargeable battery supplier have the cell potential of about 1.2 volts. Now we can take a view at the good selling of Ni-Cd rechargeable battery.
 
Since NiCd batteries are fairly cheap to produce, they are also relatively inexpensive to buy and are used for many different types of devices. Low internal resistance (less than half the equivalent NiMH cells) is one of its advantages with high rate charge and discharge rates possible. That is the reason for the blossom of market Li-ion rechargeable battery wholesale in China. Of course, charging process is strongly endothermic-the battery cools during charging. This makes it possible to charge very quickly, as the I2R heating and endothermic chemical reaction counteracts each other.
 
Sometimes customers would like to buy hot sale battery charger which is also okay for your power devices.
