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 or 24V 2AH-150AH lead-acid batteries of cars motorcycles. It is forbidden to charge lithium batteries. High frequency pure copper transformer is ideal for powerful fast charging. Multiple Safety ProtectionLow voltage protection, over voltage or over current or short circuit or over temperature protection, to ensure your safety. The charger automatically stops after being fully charged. Pulse technology produces the right repair activation effects. Easy to use Precise CPU control of temperature, intelligent charging, no setting required, automatic charging when the red clip is connected to the battery positive(and), the black clip is connected to the battery negative(-). Durable MaterialThe shell is adopted of high quality flame retardant ABS, which is anti-corrosion durable. anti-electrocution. Microprocessor Control (CPU). 3-STAGE AUTOMATIC CHARGING: This is a fully automatic battery charger with 3 charge stages. Automatic charging rotects your battery from being overcharged.
