What is the battery's rated capacity? 
Refers to a certain discharge conditions, the battery discharge to the release of electricity cut-off voltage. IEC standards for nickel-cadmium and nickel metal hydride batteries in the 20 + _ 5c environment to 0.1C 0.2C charge for 16 hours to discharge to the 1.0V power released when the battery's rated capacity to C5 and for lithium-ion battery that , provides that at room temperature, constant current (1C) constant voltage (4.2V) under the control of the charge, charge 3 h and then discharged to 2.75V when to 0.2C, the release of electricity to its rated capacity battery capacity, battery capacity units Ah, mAh (1Ah = 1000mAh). 

What is the residual discharge capacity of the battery? 
When the rechargeable battery with large current (such as 1C or above) the discharge, because the diffusion rate of the current existence of the Ambassador of the "bottleneck effect" that leads to the battery when the capacity has not been fully released to reach the terminal voltage, and then a small current, such as 0.2C can continue to discharge until the 1.0V / branch released when the capacity is called the residual capacity.
