What causes a Magotan battery to suddenly lose power after more than two years?

Difficulty starting the car: When there are no other factors, if the car suddenly becomes difficult to start, it may be a sign that the battery is about to fail. Dimming lights during idle: For example, when waiting at a red light or temporarily parked, the headlights suddenly dim. This is caused by a decrease in the engine's charging power during idle. Below is relevant information: Specific causes: Battery fault light illuminates. When the battery fault light comes on, it is a reminder to have the battery inspected and repaired at a service center. Unusual noises during startup: As the battery's discharge capacity weakens, the starter may operate poorly and produce a squealing sound, which is particularly noticeable in low temperatures. Solutions: If a Volkswagen Magotan experiences a dead battery and cannot start, it can be jump-started using another vehicle, towed to a repair shop for charging, or charged on-site using a portable charger for the car battery.
I recently encountered the issue of my Magotan's battery suddenly dying after just over two years. Based on personal experience, battery aging is the main culprit. Typically, car batteries last between 2 to 5 years. Although the Magotan's original battery is of good quality, after more than two years, the internal plates or electrolyte may degrade, leading to insufficient charge retention. My car is mainly used for short daily commutes, with each drive lasting only about ten minutes. Frequent engine starts without sufficient charging time prevent the battery from fully charging. Weather changes also have a significant impact. Last winter was particularly cold, causing the battery performance to degrade faster. Additionally, having devices like a dashcam or navigation system running continuously drains the battery overnight. It's advisable to regularly check for electrode corrosion. If you notice sluggish starts, it's a sign of aging. For prolonged parking, using a power bank or smart charger for maintenance can help. Replace the battery promptly with a reliable brand to avoid compromising driving safety.
As a seasoned driver with years of experience driving the Magotan, I believe that if the battery suddenly dies after just over two years, it's mostly due to an issue with the charging system. A malfunctioning alternator or voltage regulator can prevent the battery from charging properly. From my experience, the first step is to measure the alternator's output voltage, which should normally be between 13.8 and 14.4 volts. If it's too low, the alternator is likely faulty; if it's too high, it could damage the battery's internal structure. With many electronic devices in the car, such as frequent use of the air conditioning and headlights, combined with short trips that don't allow sufficient recharge, the battery gradually weakens. Don’t forget to check if the belt is loose or worn, as this can reduce the alternator's output. For maintenance, I recommend not letting the car sit unused for more than a week, as prolonged inactivity can lead to power leakage. If you replace the battery, consider installing a voltage monitor to alert you to potential issues. Safety comes first, as this issue can lead to starting failures and potentially cause accidents.
