What are the reasons for battery drain in the Volkswagen Tayron?

[LaEsther]

There are several reasons for the short battery life in the Volkswagen Tayron, including improper personal usage and battery quality issues. The specific reasons are as follows: Improper personal usage: Short driving distances leading to insufficient battery charging; prolonged use of high-power electrical devices; electrical appliances left on after the vehicle is locked. The car's engine powers the headlights or onboard electrical devices via the alternator while running. Once the engine is turned off, the alternator stops supplying power, and all the load shifts to the car battery. Battery quality issues: Insufficient power storage due to poor battery quality; short circuits or open circuits between battery cells, or loose battery terminal clamps; current leakage from the vehicle body. When the active material inside the battery falls off and fills the slots, it creates a circuit between the positive and negative plates, causing the battery to discharge.
