1) As you have a very good battery charger, the problems you were having with the GP batteries were clearly not caused by something basic like one uncharged cell.
2) Also, with your charts we can see that your four cells all supply a decent voltage at 500mA.
3) And from what I gather from your next-to-last message, a different set of batteries (the Sanyo ones) seems to work fine, so it's probably not the camera.
So perhaps the problem is that the tests you used to validate your GP batteries are not correct? Your tests were conducted at 330 - 500 mA, but perhaps the camera uses a much higher current (maybe 1-2A?), and at this higher current the GP battery's voltage drops significantly, whereas the Sanyo ones are able to cope better.
I have no evidence for any of this, but it's the most likely explanation I can think of based on all of the observations posted so far.

Battery charger still available - the battery itself is now gone.

The battery is now almost sold - pending payment and delivery.

A never used, brand new K-BC109 battery charger. Came in the box when I bought my K-r camera, but unneeded as I'll only be using AA batteries.
The charging block and both supplied mains adapters (UK and European) included - £25. Available from Central London, prefer to transact in person.

Four days ago I bought my first SLR, a K-r.
As I also purchased the AA battery holder to go with it, I see no use for the included Li-Ion battery.
Therefore it's now for sale - a brand new D-LI109 battery, never taken out of its wrapping, for £40. It's available from Central London, and I'd prefer to transact in person. Please let me know if you're interested.

A very odd experience - in effect you're telling them what price they'll sell something to you for.
In the end I got aggrevated with them and ended up making the trip to SRS in Watford.
