Ordering two of these from B&H with Purolator shipping (includes shipping and duty) cost a little less than 50% pre-tax for an OEM Pentax battery here in Canada. And they were here within 3 days. Used the batteries through a 1600 photo shoot over two days and only had to use one of the spare batteries, and it didn't die. At least as good as OEM and I don't think the slight voltage difference matters.

The camera eats this battery alive. I can be shooting for the day and the battery, after a full charge, will be down to one third power before 100 shots.
It is better than having one battery, but its output is severely short and it takes four to six hours to recharge.

This is not the first one I have purchased. They do have a limited life span with life span dependent upon usage. It performs well and is dependable. Looking forward to a couple of years usage.

              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!

                        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.
