Intelligent Digital DisplayThe battery 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 forbidden 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 automatically stops after being fully charged. Pulse technology produces the good repair and activation effects. Easy to use Precise processor 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-electric shock.
