Discharging Battery
Batteries can be discharged by constant-current.
An external resistive load and switch is required.
Constant-Current Discharging of Battery
The discharge resistance is derived from the following formula.
Open-Circuit Voltage of Battery (V)
R
L
= (Ω)
Discharge Current (A)
Open S1. Turn the power supply’s POWER switch ON.
Press the PRESET key and set the discharge current with the CURRENT dial.
See “Operating as a Constant Current Power Supply” on how.
Set the maximum voltage with the VOLTAGE dial.
Deriving the maximum output voltage(V
MAX
):
V
MAX
=open-circuit voltage of battery-discharge terminal voltage (V)
When finished, press the FUNC. key again to finalize settings.
Close S1 and press the OUTPUT key to begin testing.
When the discharge terminal voltage is reached, open S1 to stop discharging.
As long as S1 is closed, the battery will continue to discharge regardless of the power
supply’s output ON-OFF status.
