Does this help?

Check half way down on the page link you posted - under "Features":

Pocket-style of fast detaching battery case
12 AA Battery Capacity

I do see that it takes 12 AA batteries. Apparently it can work just on 6 batteries as well. Presumably 12 batteries will last twice as long, pairs of batteris being in parallel. The can't all be in series, that will add up to 18 volt! That will blow the circuitry, I think. Nonetheless, I need AA support just for peace of mind. I dread the possibility of proprietary batteries not being available down the road. It has happened to me before. You are forced to buy a new product, even if you are perfectly happy with what you have. Cheers.

It looks all NP-400 batteries have discontinued. There is no cheap replacement anymore.

The replacement battery that I bought for my new K20D through Amazon has 2000 mah. Don't know if that's accurate, or not, but it sure does work fine. Also picked up an inexpensive charger online that comes with a European adapter and auto plug. I've used it in my vehicle, and it charges fine.

What about a charging those Np400s? Works with Pentax charger?
I am actually using both the minolta and Samsung versions of the charger and batteries. Chargers and battery are styled identically. How did Pentax even get the licence for the battery I still don't understand...

I used the np400 from minolta and the cheaper 'ebay' battery in my K20 for a year (i rotated 3)and never had a problem. I still have one Delkin NP400, 1500mah battery and a knockoff ac/dc charger left over. if anyone in the CONUS is interested pm me and i'll ship both to your door for $15
