Restore and maintain 12V lead-acid batteries — 6A max output, pulse desulfation, temperature-compensated charging, without manual monitoring
Why is this charger perfect for you?
✔ Pulse repair for aging batteries: The one-click repair function helps revive under-voltage, sulfated, or old lead-acid batteries. Restoring battery performance can help extend battery life and reduce replacement costs.
✔ Built-in safety protections: Protection against overvoltage, short circuits, reverse polarity, and overheating helps safeguard both the charger and the battery during charging.
✔ Automatic temperature compensation: The charger detects ambient temperature and adjusts charging voltage to help prevent overcharging in summer and undercharging in winter. Intelligent multi-stage charging manages the process after connection and mode selection.
