How it works and how to install it
Connect the clamps or ring terminal cables directly to the battery terminals, select the voltage (6V or 12V) and battery type using the MODE button, then plug the charger into a 220V outlet — the charger automatically starts the multi-step charging process, adapting the current according to the battery's condition. No special configuration or advanced technical knowledge is required. Once the battery reaches full capacity, the device automatically switches to maintenance mode, preventing overcharging.
