Intelligent Digital DisplayBattery charger intelligent display screen shows voltage, current, battery capacity, temperature, etc. Which allows you to observe the charging status of the battery. Wide ApplicationThe charger is suitable for 12V/24V 2AH-150AH lead acid batteries of cars and motorcycles. It is prohibited to charge lithium batteries. High frequency pure copper transformer is ideal for powerful and fast charging. Multiple Safety ProtectionLow voltage protection, overvoltage/overcurrent/short circuit/overheat protection, to ensure your safety. The charger will automatically shut down after being fully charged. Pulse technology produces the good repair and activation effects. Easy to use Precise CPU control of temperature, intelligent charging, no adjustment required, automatic charging when the red clip is connected to the positive(+) battery, the black clip is connected to the negative(-) battery. Durable MaterialThe shell is adopted of high quality fireproof ABS, which is anti-corrosion and anti-electrocution. Microprocessor Control (CPU). 3-STAGE AUTOMATIC CHARGING: This is a fully automatic battery charger with 3 charge stages. Automatic charging protects your battery from being overcharged. So you can leave the charger connected to the battery indefinitely. 3-stage chargers are suitable for most battery types including Calcium, Gel and AGM, Wet batteries. They may also help restore drained and sulphated batteries. Types of batteries: Most types of lead acid batteries including Calcium, GEL and AGM, Wet,EFB, etc..
