In the constant current charge, the voltage changes as follows: rising, steady, rising (up to a certain extent can not be recharged, recharge is called overcharge)
In the constant current discharge, the voltage changes are: decline, steady, decline (down to a certain extent can not be discharged, and then called over discharge)
It can be seen that in the constant current charge and discharge, the voltage has a smooth process, and the steady value is the charge and discharge platform.
The more stable and longer time the better of the level, because the Battery is to use that period of voltage stability.Such as: nominal 3.7V Lithium Battery platform voltage is about 3.7V, the nominal 3.2V iron Lithium Battery platform voltage is about 3.2V.
