    Just bought it and charged it up. I have used it for the first day. It did not fit the Pentax charger tight. Just a little loose. I did charge fine. Every thing good so far.

          Don't get anything else. It's just as good as the Pentax-branded unit as far as I can tell, and costs half as much, I use them with a K3.

          Charge time - 2 hours!!!
          Lasted over 1 1/2 days of fairly heavy use in 35° - 40° temps.

              I bought this as a spare for my Pentax K-3, and it seems to work fine, at a very reasonable price. Putting it in the battery grip included with my camera makes the grip appreciably lighter than when I load it with AAs.

                Can't say how long this particular battery will last for the long haul. Based upon previous Watson offerings, I felt confident buying this versus Pentax's own at nearly double Watson's price. I was a bit confused by the 1800mAh rating, but B and H jump right in to confirm this works with my K-3 prestige series - indeed it does! Watson batteries? It's Elementary, just buy them!

                        I have a K-5 IIs and a K-3, both with battery grips. I have 3 Pentax batteries and this model. I can't see any performance difference in durability between them.

                        Comments about Watson D-Li90 Lithium-Ion Battery Pack (7.4V, 1800mAh):

                        Did a bit of research and came to the conclusion that third party batteris are pretty much a shot in the dark. Reviews for the same brand are all over the place.

                        Howqever the battery for the Pentax K-5II takes a very long time to charge so haveing a backup is a must. This battery sells for about half the OEM equivelent. I've only had this one for about a week, but so far it seems to work as advertised.

                        I haven't used it to exaustion, so I cannot really say how it compares to the OEM battery, for number of exposures, but it holds a charge, and powers the camera. In short it does what it's supposed to do so far.

                        I won't know how well it stacks up over the long run for some time, but if it's extreemly good or extremly bad I'll update this revies.

                                Comments about Watson D-Li90 Lithium-Ion Battery Pack (7.4V, 1800mAh):

                                I'm trying this battery as opposed to the camera manufacturer's own battery due to the more than double cost of the manufacturer's. Will have to wait to see if I made a wise decision.
