7.3 Charge-to-discharge & discharge-to-charge cycle NiMH/NiCd battery
8. 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.
8.1 Charging Pb battery
Set the sequence on the left and the number of cycle
on the right. You can use this function for balancing,
refreshing and break-in the battery. To avoid rising
temperture of the battery, there will a brief cool-off
period that already fixed at 'User setting' after each
charge and discharge process. The cycling number
ranges from 1 to 5.
To stop the process, press Batt type/Stop key once.
You can change the discharge or charge current by
pressing Start/Enter key once during the process. The
audible sound indicates you the end of process.
At the end of the process, you can see charged or
discharged electric capacities of the battery at each
cyclic process.
By pressing INC or DEC button, the screen shows the
result of each cycle in order.
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 7.0A 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.
