What is charge/discharge rate?
3. Charge/Discharge Rate (C) The charge/discharge rate measures the speed at which the lithium battery can be charged or discharged, expressed in “C. Discharge Rate (C) = Discharge Current (A) ÷ Rated Capacity (Ah) High Rate Applications: Suitable for rapid charging and discharging scenarios, like electric vehicles.
What is a good battery discharge rate?
Battery manufacturers rate capacity of their batteries at very low rates of discharge, as they last longer and get higher readings that way. This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C.
What is a 20 hour battery discharge rate?
This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.
