What is the voltage of a BMW battery?
1 Answers
BMW battery voltage is 12V. Normal battery voltage: The normal battery voltage ranges between 11.8V and 12.8V. After starting, the battery voltage should be between 13.2V and 14.8V. As long as the voltage during startup is not lower than 11V, it is considered normal. Both excessively high or low battery voltage can cause certain impacts. Precautions for battery voltage: When charging a lead-acid battery, wear protective clothing. Ensure there are no sparks near the battery during charging, and smoking is strictly prohibited. When charging one or multiple batteries in parallel, the charger voltage should not exceed 16V. Connect the positive lead of the charger to the positive terminal of the battery and the negative lead to the negative terminal. When turning on the charger, start with the lowest current setting and gradually increase it until the battery begins to accept current. For a deeply discharged battery or a battery in cold conditions, this process may take several minutes. If acid mist is emitted from the battery vent or the battery temperature exceeds 52°C, charging must be stopped immediately, as these signs indicate the battery is damaged and needs replacement. Charging is considered complete when the current drops below 1A or after more than 24 hours of charging, at which point charging can be stopped.
