my Skoda Octavia NFL (2020-Present) battery keeps dying what could be the reason

Solution

1. Preparation

• Gather tools and parts required.
• Disconnect the negative battery terminal using a wrench to ensure safety.
• Safety warning: Allow the engine to cool before working on electrical components.

2. Battery Replacement (if necessary)

1. Remove the Old Battery

   • Loosen and remove the positive terminal followed by the negative terminal.
   • Carefully lift the battery out of the tray.
   • Dispose of the old battery at a proper recycling facility.

2. Install the New Battery

   • Place the new battery in the tray, ensuring it is secured properly.
   • Connect the positive terminal first, followed by the negative terminal.
   • Ensure the connections are tight and free of corrosion.

3. Alternator Testing and Repair (if necessary)

1. Inspect the Alternator

   • Visually check for any damage or loose connections.
   • Use a multimeter to measure the output voltage while the engine is running.

2. Replace or Repair the Alternator

   • If the output is below 13.5V, consider replacing the alternator.
   • Disconnect the battery, remove the alternator belt, and unbolt the alternator from its mount.
   • Install the new alternator in reverse order of removal.

4. Addressing Parasitic Draw (if necessary)

1. Identify the Circuit Causing the Draw

   • With the multimeter connected for current measurement, systematically remove and replace fuses until the draw drops to an acceptable level (typically below 50mA).

2. Repair the Faulty Component

   • Once identified, repair or replace the component causing excessive draw (e.g., a malfunctioning module or accessory).
