9.1. Charging Lead Acid (Pb) Batteries
9.2. Discharging Lead Acid (Pb) Batteries
Set the charge current on the left and the nominal voltage
on the right. Charge current can be set from 0.1-6.0 A. The
voltage must match the battery being charged. Press the
„START/ENTER“
key for more than 3 seconds to start
charging.
The screen will display the real-time charging status. Press
the
„START/ENTER“
key to alter the charge current. Press
the
„START/ENTER“
key again to store the parameter
settings you set. Press the
„BATT TYPE/STOP“
key to end
the program.
Set up the discharge current on the left and the nominal
voltage on the right. The discharge current can be set from
0.1-1.0 A. The voltage should match the battery being
charged. Press the
„START/ENTER“
key for more than 3
seconds to start discharging.
The screen displays the real-time discharging status. Press
the
„START/ENTER“
key to alter the discharge current. Press
the
„START/ENTER“
key again to store the parameter
value you set. Press the
„BATT TYPE/STOP“
key to end the
program.
9. Charging/Discharging Lead-Acid (Pb) Batteries
This program is only suitable for charging a lead-acid (PB)
type battery with a nominal voltage range of 2 to 20 volts.
Lead acid (Pb) batteries can only deliver current lower in
comparison to their capacity. The same restriction applies
to the charging process. Consequently, the optimum charge
current for lead acid (Pb) batteries is only 1/10 of its rated
capacity. You cannot fast charge lead acid (Pb) batteries.
Please refer to the following specifi cation regarding charging
and discharging lead acid (Pb) batteries.
· ·
Nominal Voltage Level:
2.0 V per cell
· ·
Maximum Charge Voltage:
2.46 V per cell
· ·
Allowable Charge Current:
0.4 C or less
· ·
Discharge Voltage Cut Off Level:
1.75 V or higher per cell
Due to the chemistry characteristic of a Pb battery, the cut-off point may be diffi cult to detect at times.
We recommend you use the
CAPACITY CUT-OFF
feature to protect the battery. Refer to the
Default User
Preferences Setup
section of this manual to set up this feature.
