1.Summary
The charger is specially designed for the lead-acid battery used in the engine. It adopts the three-stage intelligent control mode of constant current fast charging, constant voltage evenly and trickle floating charging. It can be charged for a long time without damage to the battery. It can maintain the full state of the battery and ensure the service life of the battery. The charger can be used in parallel with the engine charging generator without disconnecting the charger during the operation of the engine.
2.Main Features

The use of aluminium for heat dissipation, good heat dissipation and high interference resistance;
Using advanced switching power supply mode, wide AC input voltage range.
Three stage intelligent charging to maintain battery power automatically.
With short circuit and reverse connection protection.
It has charging voltage fine tuning function.
It has LED led, which can indicate the working state of the charger.
3.Charging Principle
The charger adopts a three-stage intelligent control mode in accordance with the characteristics of lead-acid batteries.
The first charging mode is “constant current mode”, when the battery voltage is lower than the preset value, it is a constant current charging stage; the charging current is rated at 6A (3A), the high current charging makes the battery power rise rapidly, the rising process is a fast charging state, the performance is character by the red charging indicator light is always on.
The second stage of charging mode is “constant voltage mode”, when the battery voltage rises above the preset value soon after charging in constant current mode, the charging current decreases as the battery voltage rises, the charger maintains constant voltage output at this time, the charging current decreases slowly and the terminal voltage of the battery is slowly stabilised at the average charging voltage value, during this process the red The charging indicator lights up. The internal timer starts timing when the evenly state is reached and the charging current drops below 0.8A (0.4A) or after approx. 3.5 hours to float charge mode;
The charger enters an evenly charge state: when the charging current is greater than 0.8A (0.4A) and less than 5.2A (2.6A).
The third stage of charging mode is “float mode”, after the battery has been charged in both modes, the battery is basically full, the charger output voltage automatically switches to the float voltage of 27V (13.5V), the charging current drops to 0.8A (0.4A), the performance characteristics of the red charging indicator goes out. The float mode charging current offsets the self-discharge of the battery and maintains the battery in a fully charged state without the need to disconnect the charger and has no effect on battery life.
