High Capacity Pentax D-LI109 1050mAh Replacement Lithium-Ion Battery for Pentax K-R Digital SLR Cameras

I always like to have at least one back-up battery.

We bought this as a back up battery to use while our other battery was charging. For that purpose, it works okay. However, it calls itself a high capacity replacement battery & I find that a little bit deceiving because it runs out of juice very quickly. For the price, it's great to have as a spare but would not have as my only battery for sure. If it held a charge longer, I could give it a higher ranking.

Good price and seems to hold a charge longer than the one that came with the camera. It also arrived sooner than expected. I now wish I had ordered two.

I purchased two of these batteries. One of the two won't power my camera up. The other one will. Compared to the original Pentax battery, these seem light.

Bought this at an amazing price and it works perfectly. Would recommend this to anyone. Would keep this in mind for gifts for family.
