This is strange. I have three chargers, one from 2009 (my K-7) and the latest from K-01 production 2012-02 and three battery's and none of them are from the P-section.

With the 645D there was a battery that had no productiondate label on it. Maybe this one was also from 645D?

It seems to me 645D has the same battery like K-5. I don't exactly - maybe it's from 645D.

It's new item IMO. Discussed at Korean forum. No links, sorry.

I see here that K-01 has such charger and battery.

BUT...we can see here that K-01 uses the old charger and battery.

But here - with letter P.

What are the mystical D-BC90P and D-LI90P? ))

So you don't know what it shipped with (maybe the K30)
Not sure what the 4th pin is for, maybe it's a proprietary connection thing to make it harder for the Chinese to knock off the battery (like sony does) so Pentax can get 8 times as much from you for one battery

Edit - Canon has batteries with 4 terminals as well. Perhaps the 4 posts is because it's actually 2 cells inside and a 4 post system will allow a faster charge.

It's interesting. Thank you, dear Eddie! The thread could be closed. IMO

Then I probably got a last run of the D-Li90 labled:

PENTAX RICOH IMAGING COMPANY, LTD. and not HOYA CORPORATION

Well, that difference turned out to be a bit less than expected, didn't it.

Interesting though.

Not much difference between the serial numbers on those batteries.

The 2012 is from my K-01 and the 2011 is from my latest K-5 (I sold an older used K-5 for sports where the shuttercount was going up).

The same thought went through my mind.

Should be worth a nice high reserve bid and an equally exorbitant 'buy-it-now'.

You think that if I put that battery in my very used K-5 Silver Limited Edition, that I can exchange that set for a brand new K-1 Full Frame?
