Intelligent Digital Display: This intelligent battery charger displays voltage, current, battery capacity, temperature, etc., allowing you to monitor the charging status. Wide Application: Suitable for 12V/24V 2AH-150AH lead-acid batteries in cars and motorcycles. Do not charge lithium batteries. The pure copper high-frequency transformer ensures powerful and fast charging. Multiple Safety Protections: Low-voltage protection, over-voltage/over-current/short-circuit/overheat protection ensures your safety. The charger automatically shuts off after a full charge. Pulse technology provides excellent repair and activation effects. Easy to Use: Precise processor-controlled temperature, intelligent charging, no adjustments needed. Automatic charging begins when the red clamp is connected to the positive (+) battery terminal and the black clamp to the negative (-) terminal. Durable Material: The housing is made of high-quality, flame-retardant ABS material, which is corrosion-resistant and anti-electrocution.
