The discharge system of battery means the discharge rate, discharge form, termination voltage and temperature of the battery..
"Discharge Guangyu VRLAB" is mainly divided into the following three stages.
A), the battery terminal voltage by float quickly fell to the open circuit voltage, when the voltage to by 2.23V dropped to about 2.13, so the process is by the floating charge voltage for open circuit voltage, not the actual open circuit voltage, so the decline in particularly fast.
B), the cell terminal voltage from the open circuit voltage began to steadily decline, the normal circumstances of the battery during the 1.80-2.06 period of the discharge is a smooth transition, the battery terminal voltage decreased steadily.
C), when the battery reaches the end voltage 1.80V, at this time if the battery continue to discharge, the discharge rate will accelerate, also during this period it belongs to the battery's over discharge process, if there is a discharge, you must promptly supplement the battery with the power, otherwise it will lead to internal battery sulfation, and recovery of the capacity will bring great difficulties.
