⚠️ Compatibility & Safety Note
Confirm the battery’s voltage, chemistry, capacity, charging limits, terminal polarity, and manufacturer recommendations before connecting the charger. Selecting the wrong voltage or charging mode may damage the battery or connected vehicle electronics.
Lithium charging should only be used with a compatible rechargeable lithium battery featuring an appropriate battery-management system. Do not use lithium mode for damaged, frozen, non-rechargeable, or unsupported battery types.
Switch off the vehicle and accessories before connecting. Attach the positive lead to the positive terminal and the negative lead to the approved negative terminal or grounding point according to the supplied instructions.
