How do I troubleshoot a faulty battery in my Vauxhall Zafira Life?

My Vauxhall Zafira Life seems to have a faulty battery. It does not hold a charge and I have to jump start it every time I want to use it. What could be the issue and how can I fix it?

Firstly, you should test the battery with a multimeter to determine its voltage and whether it is holding a charge. If the voltage is low, you may need to replace the battery.

Another possible issue could be a faulty alternator. This component charges the battery while the engine is running and if it is not functioning properly, it could be the root cause of your battery problems.

It is also important to check for any corrosion on the battery terminals. Use a wire brush to clean them and ensure a good connection with the battery. This can sometimes solve charging issues.
