Good evening

I have been having issues starting my car for a few months and maintaining a charge. I bought the car 2 years ago for commuting around 65 miles per day which I did until January of this year. Since then without going for a decent drive (20 miles either way) I can only use it 3/4 times before it won't start. I have had Green Flag out to check the battery and have said it runs fine (around 14.6V) so apparently that isn't the issue. At the same time they advised that the alternater is fine. I have spoken with someone who has a decent knowledge and advised to get my battery rechecked as it can still show a good output when all the cells might not be working properly.

My queries are: can the battery show a good output when not 100% and is thet anything else I should be looking at apart from the wiring?

Thanks

Gary
