Why is my Vauxhall Combo Life's battery not charging?

I recently noticed that my Vauxhall Combo Life's battery is not charging properly. I've checked the connections and they seem fine. What could be causing this issue?

It is possible that there could be a problem with the alternator. It may be necessary to have it checked and potentially replaced.

Another potential cause could be a faulty battery. Have it tested to see if it needs to be replaced.

Make sure that the battery terminals are clean and free of corrosion. This could also be preventing proper charging.
