When the battery is fully charged, it will automatically check the battery voltage every two hours. If the voltage is low, it will automatically enter the charging mode.4. The output current is as high as 4A, and it is widely used in motorcycles and car batteries.5. When connected to the battery, the battery capacity percentage can be displayed, which is very clear to see.Specification:Item Type: Battery ChargerMaterial: ABSCharging Current: 4AApplicable Object: BatteryCharging Time: 10hSize: Approx. 127x67x37mm/5x2.6x1.5in5-stage charge mode:2. If battery is still less than 11V, charger will desulfate it for 24 hours with PWM pulse.4. After charged fully with current less than 0.5A, will come into maintenance.5. When trick current is less than 200mA, will cutoff charging completely. Sequently it would detect battery every 2 hours, and will pulse recharge battery if battery drops less than 13V..Package List:1 x Battery Charger1 x Stardard Cable
