Charging/Discharging and Discharging/Charging Cycle of a NiCd/NiMH Battery
9.4 The Lead-Acid Programme (Pb)
Charging a Pb Battery in Charge Mode
This programme is only suitable for charging lead-acid batteries with a nominal voltage from 2-20 V. The lead-
acid battery is completely different from a NiCd/NiMH battery. These can only deliver a current lower in
comparison to their capacity. The same restriction applies to the charging process. Consequently, the optimum
charge current can only be 1/10 of the capacity. A lead-acid battery is not suitable for fast charging.
Due to the chemical characteristics of a lead-acid battery, the cut-off point may be difficult to detect
sometimes. We recommend using the capacity cut-off feature to protect the battery. Press START/ENTER to
activate the function, modify the parameters with INC/DEC, and confirm with START/ENTER.

Set up the sequence on the left and the number of cycles on the right. The
cycle number ranges from 1-5.
Press TYPE/STOP to end the process, press START/ENTER to modify the
charge current.
a. battery type
b. elapsed time
c. discharging or charging current
d. battery voltage
e. discharged or charged capacity
When approaching the end of process, you will see the battery's capacity
being charged or discharged. Press INC/DEC to display the result.
Set up the charge current (left) and the nominal voltage (right). The current
ranges from 0.1-5.0 A. The voltage should match the voltage of the battery
being charged. Start the charging programme by holding START/ENTER
pressed for 3 seconds.
This display shows the real-time charging status. Press START/ENTER to
modify the charge current, press again to store the set value. Hold
TYPE/STOP pressed for 3 seconds to stop the charging process.
