Your ultimate tool for battery care. From quick charging to long-term maintenance and reviving depleted batteries, the BC-400 PRO does it all.

Monitor every detail in real-time! The clear LCD screen shows ambient temperature, voltage, charging current, and battery capacity percentage, putting you in complete control of the charging process.
🛡️ Multi-Layer Safety Protection
Charge with absolute confidence. Our charger is equipped with six key protection systems: Short-Circuit, Reverse-Polarity, Over-Voltage, Over-Charge, Low-Voltage, and Over-Temperature Protection to safeguard both the charger and your battery.
🌡️ Smart Temperature Control
An integrated cooling fan automatically activates when the internal temperature exceeds 45°C (113°F), ensuring optimal performance and longevity by preventing overheating during intensive charging sessions.

Bring "dead" batteries back to life! Unique repair and desulfation modes can safely start charging from 0V, breaking down sulfate crystals on lead plates to restore battery health and extend its lifespan.

Perfect for seasonal storage. Once the battery is fully charged, the charger automatically switches to a float/maintenance mode, monitoring voltage and providing a trickle charge only when needed—zero risk of overcharging.
