How to detect the health status of BMW x 1 hybrid battery?

1. First, measure the voltage. Measure the battery voltage with a battery meter or multimeter. Under normal circumstances, the no-load voltage of the battery is about13v, the full-load voltage is generally not less than12v, and the starting voltage is not less than 9.5v.. If the battery voltage is low, it may be difficult or impossible to start the vehicle.

2. Second, honk the horn to check. After the battery has been used for more than one year, you can honk the horn first when you start the car. If the horn doesn't ring as before, it means the battery is dying.

3. For the last headlight inspection, turn on the headlights for inspection. If the light is white, the battery is normal. If the light is red and black, the battery is insufficient.
