14、Charge Rate—The rate, usually expressed in several rated capacity at which electrical current is charged into the battery.
15、Constant Voltage Charge—When charging, a method to keep constant voltage to charge the battery.
16、Constant Current Charge—When charging, a method to keep constant current to charge the battery.
17、Trickle Charge—A charge at a low rate, balancing losses through local action and periodic discharge, to maintain a battery in a fully charged condition.
