Intelligent Digital Display: carousel data automatic display, can show / current / Voltage / Simple power supply: accurate CPU temperature control, intelligent charging, does not require adjustment, automatic charging when the battery is connected to the power supply red positive (+) battery fixing clip black with negative (-) battery fixing clip pure copper with high frequency transformer: powerful and fast charging MULTIPLE PROTECTION: Over voltage protection, reverse connection protection (for positive and negative connection error), short circuit protection, over current protection, over temperature protection, over voltage protection. Scope of application: It is strictly forbidden to charge the lithium battery. Suitable for 12V 4AH-100AH lead-acid battery (AGM, GEL, MF, SLA, VRLA), diagnoses and repairs battery problems and extends battery life of cars, motorcycles, lawn mowers or boats . Voltage and power detection: connect the battery without plugging in the power supply, it is possible to display the remaining battery voltage. Keep track of your battery status and see if you need to recharge. Intelligent charging, automatic shutdown when fully charged, one button repair. Winter and summer mode: The charger automatically detects the outside temperature, automatically starts winter and summer mode, and automatically selects the appropriate voltage for the charging by temperature without setting. Product Description Features: Smart charging, automatic shutdown when fully charged One button repair Winter and summer charging mode Pure copper high-frequency transformer: powerful power and fast charging Multiple protection Intelligent digital display ATTENTION It is strictly forbidden to charge the lithium battery. Input voltage: 110-240V 50-60Hz Output voltage: 12V Output current: 6A (72W MAX) Battery type: All SLA batteries ( Wet, MF, GEL, VRLA and Flooded), AGM (EFB), LiON Warning: Do not charge the lithium battery. Material: ABS + PC Waterproof: IP65 Operating temperature: -10~45C (14~113F) Weight: 0.49 kg Dimensions: 22 x 11.2 x 6.5cm Describe 1. When charging is complete, the battery charger automatically shuts down. Smart charging makes the operation more convenient. 2. When the battery voltage is lower than 12.5V, the charger will activate the automatic charging function without you having to operate it again. Note: In order to maintain the life of the charger, it is recommended to turn off the power after charging more than 48 hours. Productive recognition Connect the battery without connecting the power supply, it can show the remaining battery voltage. Keep track of your battery status and see if you need to charge. Intelligent charging, automatic shutdown when fully charged, repair button Winter and summer mode The charger automatically monitors the outside temperature, automatically starts winter and summer modes and selects the voltage of appropriate charging according to temperature Step (1) Connect the red terminal to the positive (+), the black terminal to the negative (-) terminal of the charger. (2) Connect the charger to a 220V household power source, the charger will start working after connection (the light will turn red) High quality materials Cold resistant pure copper soft core and fully wound alligator clip Universal wide voltage cold and freeze resistant Safe and fast Pure copper high-frequency transformer Powerful, fast charging Cooling fan Low-voltage silent cooling protection fan: can achieve the best dissipation of heat, greatly extends the life of the charger with heatsink. Multiple protection and range Multiple protection Overvoltage protection, reverse polarity protection (for faulty positive and negative connection), short circuit protection, over current protection, over temperature protection, over voltage protection Scope It is strictly prohibited to charge the lithium battery. Suitable for 12V 4AH-100AH (AGM, GEL, MF, SLA, VRLA) lead-acid batteries, can diagnose and repair battery problems and extend battery life of cars, motorcycles, lawn mowers or boats
