9. Pb( lead-sulphuric acid) battery program
This is programmed for charging Pb( lead-sulphuric acid) battery with nominal
voltage from 2 to 20V. Pb batteries are totally different from NiCd or NiMH batteries.
They can only deliver relatievely lower current compare to their capacity, and similar
restrictions definitely apply to charge. So the optimal charge current will be 1/10 of
the capacity. Pb batteries must not be charged rapidly. Always follow the instruction is
supplied by the manufacturer of battery.
When you are willing to alter the parameter value in the program, press Start/
Enter key to make it blink then change the value with INC or DEC key. The value will
be stored by pressing Start/Enter key once.
9.1 Charging Pb battery
Set up the charge current on the left and the nominal
voltage of the battery on the right. The charge current
ranges from 0.1 to 6.0A and the voltage should be
matched with the battery being charged.
Start the charge process by pressing Start/Enter key
for more than 3 seconds.
9.2 Discharging Pb battery
Set discharge current on the left and final voltage on
the right. The discharge current ranges from 0.1 to
1.0A.
To start the process, press Start/Enter key for more
than 3 seconds.
The screen displays the current state of discharge. You
can alter the discharge current by pressing Start/Enter
key during the process. Once you change the current
value, store it by pressing Start/Enter button again.
To stop discharging press Batt Type/Stop key once.
The audible sound indicates you at the end of process.
The screen displays the state of charging process. To
stop charging forcibly, press Batt type/Stop key once.
