Hello and welcome to Just Answer

I'd 1st check that the alternator is actually charging the battery in the car by taking a battery voltage reading with the engine off then another with the engine running. The 2nd reading should be higher than the 1st and climbing steadily. And also check that the alternator is secure to the engine as this provides the ground for the charging circuit and make sure that the engine / gearbox earth strap is secure and the contacts are clean and bright.

if the alternator appears not to be working - take it to a electrical specialist and ask them to test it as sometimes you can replace just the diode pack and this will repair the alternator without requiring replacement

And one last thing is – how old is the battery? – As even good quality ones need replacing every 5 years and faulty battery just won’t hold a charge

Also check then check that the main battery cables are on tight and the terminals are clean and bright. Do the same for the engine / gearbox ground strap.

and there should also be a ground wire that runs out of the engine bay wiring loom and is terminated onto the engine with a ring terminal
