Condensation Problems (Maybe)

[Dead Eye]

A dying battery will spin the engine but not produce the required spark, and will then die as it can't maintain the cranking amps.

Yes, but the thing was, after I'd bumped it successfully, I then rode to Wickham Square and it started fine when we left, ditto when we left Box Hill and the same again when I went out in the evening and then came back. On all of those occasions it was turning over just as quickly as it was when I had tried to start it in the morning.

I've also had it start (eg the time I was in Brighton) when it was a lot more sluggish to turn over, but did fire, hence why I don't think this is related to the previous issues but may be due to condensation causing the power to earth to the engine casing instead of sparking the plug.

My thou is generally harder to start when it is cold in the mornings after being left overnight in a garage. However, leave it all day parked at work and it is fine to start at the end of the day to go home. The lower temperatures and longer duration before starting make a difference. You wouldn't have been stopped for long enough at your destinations for the same conditions to apply. This means that even if it is a shagged battery, you wouldn't have as much or any difficulty in re-starting your bike - just as your described.

If my point got lost in that, I'm just saying don't take the evidence you've presented to mean that the battery is ok.
