The automatic voltage detection handles 6V, 12V, and 24V systems without manual intervention, whilst a dedicated selection button enables lithium battery charging for modern applications. The advanced zero volt charging capability can recover completely discharged batteries, and the integrated sulfation repair function helps restore degraded older batteries to working condition. The 13.5V DC power supply mode provides crucial battery support during extended diagnostic work, maintaining stable voltage to preserve vehicle electronics and diagnostic data. This feature is particularly valuable for modern vehicles with sensitive electronic systems that require constant power during testing procedures. Built-in safety features include reverse polarity, short circuit, over temperature, and overcharging protection. The intelligent cooling fan operates only when needed, reducing noise in the workshop. The intuitive LED screen displays real-time charging voltage, current, battery capacity percent
