I use 4 of these batteries for 3 years alternately in my Pentax K10D / 20d cameras. At first I was a bit confused because several Minolta DSLR are listed on the package next to the Pentax, obviously the battery type is identical. The performance and processing perspective, I can not tell the difference to the over-priced Pentax-original - brand quality from AccuCell (is also offered as AccuPower) precisely. Strong buy recommendation!
