What is the normal battery voltage for Volkswagen Lavida?
2 Answers
Vehicle battery voltage should remain between 11.8V-12.8V before starting, and between 13.2V-14.8V after starting is considered normal. Effects of too high or too low battery voltage: Both excessively high or low battery voltage can cause certain impacts. Regular checks on battery condition are recommended. When battery voltage drops below 10.8V, immediate charging is required. If battery voltage is too low, the car may experience difficulty starting or even fail to start; if battery voltage is too high, it may damage the battery. Long-term vehicle parking: The battery can be charged by the alternator while the car is running. If the vehicle is parked for extended periods, it can easily lead to battery power loss, resulting in failure to start. Therefore, during long-term parking, it's advisable to start the vehicle at least once a week. The alternator will charge the battery, typically requiring idling for more than 5 minutes.
The normal voltage range for the Volkswagen Lavida's battery is crucial. When measured with a multimeter in the off state, it's ideally between 12.4 to 12.8 volts. If it drops below 12 volts, be cautious as the battery might be aging. During startup, the voltage will dip but shouldn't fall below 10 volts, otherwise, ignition becomes difficult. Once the engine is running, the alternator starts charging, and the voltage should read between 13.7 to 14.7 volts, which is normal. My old Lavida, after five years of use, once stalled in an underground garage during winter—measuring only 11 volts. Replacing the battery solved the issue. Regular maintenance shouldn't just focus on engine oil; pouring hot water over the battery terminals to remove rust can extend its lifespan.
