So my battery ran down recently. The battery light came on and off at that time. The battery tests good.The alternator is charging high 13's and low 14's voltage. The battery does well when sitting. It has like 12.85 when tested before first start of the day. After starting it, I check the voltage at the battery, and usually it's not charging at all right away. After a short period of time, around 30 seconds or less it begins charging. It seems to do this consistently after sitting overnight. Once it's charging, it stays charging all day.Anyone have any idea of why?

Normal. Honda does it to save fuel

I knew my 2012 did that but not my 05.I had wondered about that being a possibility? Thank you.

and that is why using aftermarket alternators does not go well in hondas...
