How often should the battery of a Volkswagen Tiguan be replaced?

[AlanLynn]

Volkswagen Tiguan car batteries should be replaced every 2 to 3 years. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or idling at low speed, it powers the car's electrical equipment; 3. When the generator output is insufficient, it can assist in supplying power to the electrical equipment; 4. It mitigates voltage surges in the electrical system, protecting the car's electronic devices; 5. It can store excess electricity generated by the alternator. Taking the 2021 Volkswagen Tiguan as an example, it is a mid-size SUV equipped with a 1.4T turbocharged engine, with a maximum horsepower of 150 PS, a maximum power of 110 kW, a maximum torque of 250 Nm, and is paired with a 7-speed dual-clutch transmission.
