After market batteries?

Is there an aftermarket brand that someone has experience with and would recommend?

DSTE Battery on eBay sold me some that have worked fine. 2200 maH, so slightly higher capacity than the OEM batteries. Though, I would not recommend their battery grip.

Wasabi aftermarket

I just purchased the wasabi 7.2V, 2300mAh batteries and charger from Amazon. I have charged and checked them but only time will tell if they last. The charger looks well made and the batteries work with the Pentax charger!
I did have an aftermarket set for the K-r that have worked very well for over a year and just sold them with the camera. They would not charge in the Pentax charger though.

+1 on the Wasabi. Have had good results with them in three different cameras, they are usually sold in pairs with a charger for under $30! I've had bad luck with other, no-name batteries, usually they wouldn't hold a full charge within a year.

I have 3 Pentax, I Pearstone from B&H that I've had for over 3 years, and a recently acquired Wasabi. I've used them interchangeably and notice no difference. I also have 2 Wasabis for my Q, and have no complaints -- they seem to be a quality alternative brand.

Purchased a Hähnel HL-PL-90 (7,2V, 1560 mAh) together with the K-5. Battery works great, although sometimes you have to nudge it on the original Pentax charger in order for it to start charging, but once it does there are no problems.

I bought a Pearstone together with my K5 and I've been using it alternatingly with the original since then without any problem or difference.

I also bought a Pearstone with my K5II and have not yet noticed any difference in usage versus the Pentax battery.

I've used Pearstones from B&H for the K-5, and also for the K-10D and a Canon compact. All have been fine. Wasabi's seem to have good reviews and are even cheaper -- maybe I'll try one of those as well...

Wasabi - I actually picked up a backup battery - well a pair. They last about 90% of the OEM in terms of images, but they recharge in about an hour. Come as a pair, with a recharger that is smaller than the OEM. There is absolutely nothing not to like!

Another vote for the Wasabi brand. I haven’t noticed a perceptible difference with the OEM battery for my K-5. However, the recharger that came with the package was a bit of a disappointment. Mine only lasted about a month. I now use the OEM charger which seems to work without issue for the Wasabi batteries. For under $30 it is hard to go wrong.

I alternate between stock and an Adorama (Lenmar) without a noticeable difference.

Pentax batteries are 3rd party batteries as well, if you did not know.
