Automatic Battery Charger Motorcycle Trickle Float For Maintainer 6V/12V 1.5A

4-stage charging process ??
Stage 1: initialization. when the charger power on then it start self-check and detect the battery correct connect. low output voltage without battery Fault LED is light. please CHECK THE POLARITY IS CORRECT. 
Stage 2: Bulk charge. using the charger highest rated current for the type of battery in use until it reaches 80% capacity( LEDs 50% blinking. 100% OFF) 
Stage 3: Absorption. the output voltage is limited to 7.3V(6V battery) or 14.5V(12V battery) while current declines as the battery charges to its full capacity without overheating( LEDs 50% ON .100% blinking) 
Stage 4: Float. at this stage. the battery is fully charged and the charger maintains the battery through pulse charging( LEDs 50% ON .100% ON)
