Operating Instructions
Inserting Batteries
The charger features four universal charge bays. Insert rechargeable batteries into the bays, ensuring correct polarity (+ and -). The charger can accommodate battery cells with a diameter up to 33mm and a length of 70mm, supporting NiMH batteries from AAA to D sizes, and Li-Ion batteries from 10400 to 32650. Up to four batteries can be charged simultaneously, though the number may be reduced for larger diameter batteries.

Charging Function
Upon insertion, the charger automatically initiates the charge mode, charging each battery individually. Batteries of different types, capacities, and charge conditions can be mixed. Once fully charged, the charger transitions to pulse maintenance charging to ensure the battery remains at 100%. Individual battery cells can be removed or inserted without affecting the charging process in other bays.
Adjustable Programming
The device allows for individual adjustment of the charge program and current for each bay. Use the "Mode" button to select the charge mode and the "Current" button to select the charge current. The default charging current is 500mA. For faster charging, three rechargeable batteries can be charged at 1500mA, or two rechargeable batteries at 2000mA.
Capacity Tester
The Powerline 4 Ultra can individually test the capacity of an inserted battery. The digital readout on the LCD display will show the remaining capacity, providing insight into the battery's health and performance.
LCD Display Information
The large LCD display provides clear information for each charge bay, including:
- Rechargeable battery voltage (V)
- Charge/discharge current (mA)
- Capacity (mAh)
- Charge duration (h)
