OUTPUT 6, OUTPUT 7, OUTPUT 8 and OUTPUT 9 can also charge lead-acid batteries.
WARNING: The following types of battery must not be connected to charger:
- Faulty or damaged cells or batteries.
- Non-rechargeable batteries (dry cells). Caution: explosion hazard!
- Batteries which are not expressly stated by the manufacturer to be suitable for the currents which
the unit produces during the charging process.
- Packs which are already fully charged or hot , or only partially discharged.
- Batteries installed in a device, or which are electrically connected to other components.
OUTPUT 3 ~ OUTPUT 5: These three outputs is using a -∆V detection to control the charging process.
The figure below shows the voltage conditions of the battery connected to the OUTPUT 3 ~ OUTPUT5
outputs during charging. When the MCU detect a voltage drop (-∆V) on top of the peak voltage, the
battery will be fed a trickle current to achieve a maximum charge effect

OUTPUT 6 ~ OUTPUT 9: These four outputs do not feature an automatic charging termination circuit.
So the charge process must be terminated manually when the appropriate charge period has elapsed.
Note:
The charge time is calculated as follows:
Charge time in hours = battery capacity (AH) × 1.4
Example: 7.2V/1.5Ah battery: Charge time in hours = 1.5Ah × 1.4 = 3.5 hours
