The capacity of this battery seems ok. Nothing to complain taking into account that it's just half the price of OEM battery.

Comments about Pearstone D-LI90 Rechargeable Lithium-Ion Battery Pack (7.4V, 1700mAh):
Works like I hoped it would, though I am still working on its first battery life.
Using it with Pentax K-5.
Really, there is no use listing pros and cons. If you have K-5 or K-7, this seems like a good alternative to Pentax Li90 that costs twice as much. Both batteries take 5 hours to charge, but the battery life is very good once charged.

Comments about Pearstone D-LI90 Rechargeable Lithium-Ion Battery Pack (7.4V, 1700mAh):
I purchased this battery as a back-up for the OEM Battery used in my K5. So far it seems to be working out great for its intended purpose. It doesn't seem to hold its charge for quite as long as the original, but then I take a LOT of photos! For the price I would definitely purchase again.

Comments about Pearstone D-LI90 Rechargeable Lithium-Ion Battery Pack (7.4V, 1700mAh):
It performs as well as the original Pentax Li90 Battery, but it's a lot cheaper. I also have a Wireless Shutter Remote from Pearstone for my K7, and it is top notch quality, I can recommend this 100% to anyone looking for a D-Li90 battery, and Pearstone seems to be a top notch company.
