System means that the discharge rate of the battery battery discharge forms, discharge, termination voltage, and temperature.
"Guangyu" VRLAB discharge is divided into the following three phases.
A), battery voltage float charging plunged by open circuit voltage, voltage to fell to 2.13 per cent from 2.23V at this time, so the process is shifted from the float charge voltage open circuit voltage, not the actual open circuit voltage, so the decline particularly fast.
B) beginning on open circuit voltage, the battery voltage declines steadily under normal conditions battery to discharge at between 1.80-No. 2.06 is a smooth transition period and steady decline in battery voltage.
C), when the battery reaches a voltage of 1.80V, if continue to discharge, the discharge rate, which also belongs to the batteries during the discharge process, if a discharge occurs, you have time to charge the battery, or cause battery sulphation, restoring capacity will lead to great difficulties.
