I think that is crap. Many folks on this forum use other brands that are not rated at 2500+
I will by a set with a 2500 rating and if they don't work I will write a letter to Pentax explaining the situation.
I've messed about with a loaner for a week now, and of my 3 sets of Eneloops at 2000mAh, 2 sets have been perfectly fine, one lasts a fraction of the time.
My one set of Maha Powerex at 2700mAh does exceptionally well as I popped those in messing around with lots of video. No problems:

I use a Maha Powerex charger (URL below; but the portable ones from Maha or LaCrosseare also excellent) and always soft charge. I cannot emphasize the importance of a good charger and quality batteries:

I have many other uses for AA and AAA batteries (kid's toys, camping stuff), so this power supply arrangement has all been a very good investment.
Compared to my K200D, the K-x does better, and frankly, has performed as well as the K-7 using a proprietary LiOn, although I haven't spent enough time with the latter to nail that down.
