Big Mike's D-LI109 Battery for Pentax K-R, K-S1, K-S2, K-30, K-50, K-70, K-500 Digital SLR Camera

I bought two of these batteries and I cannot tell the difference between them and the battery that came with my camera. They charge just as fast and seem to last just as long.

Solid battery to have now I don't have to worry about running out of a charge halfway through my day!

So far I have not had any problems with this battery. It's always good to have a second battery back up especially when you are traveling.

There was a time when you had to pay a fortune for spare camera batteries. You can't not love this for the price.

works like a charm--perfect match for this camera

the battery expanded and i was not able to remove it by myself. I need some professional help on it.it was working great but i got a crap.

Works great. Lasts as long as the original battery. Has now been through several recharge cycles.

This battery doesn't hold a charge as long as the Pentax battery that came with the camera. I haven't done any scientific testing, but my guess would be that is lasts about 60-70% as long as the Pentax battery. The best option is to buy a cheap AA battery adapter here on Amazon for about $7 and get the rechargable AA Eneloop batteries (normal power, not the XX kind).
