12 Volt 20 Amp 3 Stage Smart Automatic Battery Charger

12 Volt 20 Amp 3 Stage Smart Automatic Battery Charger
You can charge 7Ah to 200Ah battery with this charger
3 Stage Charging information is as follow
Constant Current Mode: When the battery voltage is lower than the charger voltage is set constant current charging mode, the battery charger provides constant charging current.
Constant Voltage Mode: Using pulse width modulation technology, precise control of the charger charging current and output voltages to ensure a fully charged battery is charged, to avoid overcharging.
Float Mode: When the battery voltage approaches the set voltage constant voltage charging mode, the charging current is reduced to set current time, battery power has been filled, the light turns green, the cooling fan stopped working. Charger automatically charging mode to trickle charge the float mode. The battery can be disconnected, or continue to float.
