Product InformationStore Part Number: SON604CC


Soneil’s Battery Charger transforms the 115 VAC into 6 VDC at about 100,000 Hz (1667 times faster than conventional charger), which requires a much smaller transformer and this results in a unit of smaller size, low weight and improved efficiency. The 604CC uses sophisticated electronic circuitry with microchips. All present day computers use switch-mode technology. Each Soneil 6 volt 2 amp ships with one each quick disconnect ring set and alligator clips.

Multi Stage charging cycle

Stage 1: Deep Discharge Charging Pulse Mode
The Charger starts charging at 0.5V and give pulse current up to 5V. This has effect of removing loose sulphation formed during deep discharge state of the battery.

Stage 2: Constant Current Mode (CC)
The charger changes to constant current 2A. When the battery voltage reaches to 7.3 V, the charging stage changes from (CC) Constant Current to CV (Constant Voltage) mode.

Stage 3: Constant Voltage Mode (CV)
The charger holds the battery at 7.3 V and the current slowly reduces. When the current reaches at 0.5 C (C= Battery Capacity), this point called the Switching Point. The Switching Point is one of the great features of this battery charger that it can adjust the current automatically according to the battery capacity. Other chargers without microprocessors are not capable to adjust the current automatically.

Stage 4: Standby Voltage Mode
The charger maintains the battery voltage at 6.9V and current slowly reduces to zero. Charger can be left connected indefinitely without harming the battery.

If the battery voltage drops to 6.0V, the charger changes from any mode to Constant Current mode and restart charging. The charging cycle will go through Stage 2 to Stage 4.

This charger ships with two types of quick disconnect connectors; alligator clips and ring terminals.
