I wasn't thrilled about having to get a proprietary battery for the Pentax K10D, but now that I have it I'm quite pleased. It's billed as lasting for 500 pictures, but if you don't use the flash or auto-review, it lasts a lot longer. The other day, I took over 1600 pictures before the battery was depleted.

Furthermore, unlike other reusable batteries, I have left these in my car in cold weather for several days and their charge stayed strong the entire time. This battery is one of the best I've used.

This battery allowed me to take a lot more shots than I expected- over 700 shots!

I already owned this battery (came with my Pentax K20D), but wanted an extra one for the long shoots. There was no question as to which battery I would purchase. Lasts many houre before needing to be recharged, or replaced when recharging is not an option.

Great response from this company. I received this item well before the ship date stated.

I am very happy to have a second power source. Plus I am happy to get the manufacturer brand for such a good price. My local store wanted almost twice the price. I also got it in 3 days. Wow!
