    Watson D-LI90 reviews

    D-Li90 Lithium-Ion Battery Pack (7.4V, 1800mAh) is rated 4.7 out of 5 by 57.
    Rated 4 out of 5 by from Good Battery for the money I was looking for a backup battery for my Pentax K-5 and, after reading a few reviews, I decided to go for the Pearstone pack.The battery has a little less mAH than the original battery but seems to pack a punch. The first baterry pack I got didn't last too long unfortunately. It only lasted me for about 150 shots. I figured out it was probably a defective pack so I call B&H's customer service who, again, didn't dissapoint. They sent me right away a new pack which seemes a lot better. After about 500 shots it still had about half life in it.This product is great for the money. I couldn't ask for more for the $ and I would probably buy a second pack just in case.

    Rated 5 out of 5 by from Saved 75% over the cost of a OEM Pentax 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.

    Rated 5 out of 5 by from As good as OEM! I needed one more battery so each of my cameras have a back up. Over 2 days and being outside in the cold shooting the battery did not let me down. Over 1000 shots and the battery didn't show discharge. For 1/2 the price I would buy again!

    Rated 5 out of 5 by from Works great in K3, I bought this as my backup battery for my new Pentax K3. It works fine. The Pentax charger is more of a trickle charger so it took a while to get fully charged but it seems to last as long as the factory battery.

    Rated 5 out of 5 by from Great value Charges up and holds the charge. Haven't had any issues with it. Considering the price, I think its a fantastic deal. Cannot distinguish any obvious difference from the more expensive Pentax brand batteries. Very satisfied.

    Rated 5 out of 5 by from good spare 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.

    Rated 5 out of 5 by from Bargain backup juice for the K-3 & grip 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!

    Rated 4 out of 5 by from it's a battery, so not much excitement. 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.
