I'm a new owner of a 2001 5spd/w AC and have some questions regarding the battery charge. When I bought my car a few days ago it had about 7/8 of the battery charged and seemed to stay at that point the first couple days. Yesterday I did quite a bit of start/go driving and noticed that the battery since then has stayed between 1/3 and 1/2 charge. I have no idea if this is normal. I would expect to see it go back to full charge. I drive about 8 miles back and forth to work at an average speed of 50mph with only a couple stops. Help?
