Mild Hybrid vehicles can restore the power of the 12V battery via jump-starting, but special attention must be paid to the particularity of their electrical systems. These models employ a dual-voltage system of 48V and 12V, where the 12V battery powers conventional electrical components such as lights and air conditioning, while the 48V battery assists with engine start-stop and energy recovery. When jump-starting, strictly use another vehicle's 12V battery or a portable jump starter, connecting only to the designated 12V jumper terminals (typically clearly labeled positive and negative points in the engine compartment). Never contact the 48V battery or related wiring, as this may cause fuse failure or circuit damage. Note that the 12V battery in mild hybrids has limited capacity; prolonged discharge may temporarily disable the auto start-stop function, requiring subsequent full recharge via an external charger. Furthermore, these jumper terminals are exclusively for starting the host vehicle and must not be used to jump-start other vehicles.
