The typical battery is only good for approximately 6 years so I would say you are due for a battery change. If you have the external voltage regulator, I would suggest you buy a replacement and as a worst case keep it as a spare. I have had similar alternator issues as you are reporting and the problem in my case was one of the exciter diodes in the alternator failed. I have submitted a post on replacing the exciter diodes at a cost of less than $5.00 if you have the DIY skills.
