Just in case, - a word of caution: The image shows two specs that I would be concerned about: Voltage: 7.4 V and capacity: 1440 mAh.
Note that the original one from Pentax is 7.2 V and 1860 mAh http://static.bhphoto.com/images/images500x500/634906.jpg I see that a few other replacement batteries on Amazon are also listed as 7.4 V or 7.2 V. While I was first concerned about this, I think it is just a marketing ploy. I read somewhere that the lithium ion chemistry produces a 3.6v open current potential difference. Some bulk cell manufactures list there cells as 3.7v just to make them look a little better. (3.6*2 = 7.2, 3.7*2 = 7.4) Now, the lower capacity means that I would be caring around a battery that is as heavy but not as capable. Some 3rd party batteries actually list the capacity that is higher than that of those by Pentax: 2150 or 2300 mAh. Of those that are currently available, Wasabi Power show 2300 mAh: http://www.amazon.com/Wasabi-Power-Battery-Pentax-D-LI90/dp/B004U6KIJS/ They even make a point about that in the description. (Ironically, they write: "Japanese cells ..." and the battery is still made in China, probably at the same factory as the others.) And "Neewer"-branded are rated at 2000 mAh: http://www.amazon.com/NEEWER-D-LI90-Batteries-Pentax-Digital/dp/B003FHZ3OS/ In May of 2011, I bought "Zeikos ZE-LI90" (for $17), which was rated for 2800 mAh. I never measured its capacity, but indeed, it seemed to be lasting noticeably longer. However, earlier this year, I noticed that its charge life became very short, only about 20-30% of what I get from the original Pentax battery. BuyDig that was selling them, discontinued them more than 1 year ago, and the only place I see them available now is Amazon: http://www.amazon.com/Zeikos-ZE-LI90-Lithium-Battery-Replaces/dp/B002ZRPWPY/ Also, within half a year one of the plastic pieces that is between the contacts broke off on one end and became a "prong". It still worked after that, but I had to make sure I pushed it in when I was inserting the battery into the camera. I hope this collection of information about D-LI90-format batteries is helpful to some PDMLers. Igor PS. Ricoh-imaging is very uninformative about the battery on their website: http://www.us.ricoh-imaging.com/accessories/Li-Ion_battery_D-LI90#!product-specs The webpage has no specifications, and the photos shows the "butt" of the battery. Boo! hociR!
