Thank you for the replies.
To sum up, it would seem that I didn't shoot myself in the foot by doing what I did, and that the status of my battery is actually not to bad.
We are about to head out for another three month cruise so will see how the battery performs during this time.
But, work well or fail, I know a lot more about batteries now than I did before thanks to the posters on this thread.
Thank you all.
Chris

Just for informational purposes, all aircraft batteries are supposed to be Capacity tested yearly, again for what it's worth only the Concorde batteries are cap tested by the manufacturer, all other batteries are required to be cap tested prior to being placed into service or they are not airworthy. Almost no aircraft batteries are capacity tested truth be known. Also at my last year renewal of my Inspection Authorization Concorde gave a class on batteries, one thing in the class that stuck was their recommendation of replacing a battery every five years, even if it passed the capacity check, see the battery is the back up electrical supply to run the aircraft radios, navigation gear and some gyros in the event of an alternator failure.
I would tell the OP that he has obviously done a very good job of maintaining his battery for it to still pass the capacity check after five years, but he might want to think about replacing the battery.

Well put. Now for a short thread drift, what do you think of the new French LH-10 Ellipse tandem seat pusher? Talk about efficiency.
