If you know me well, you should know that I seldome use third party stuff unless they are really good. Here I'm doing a short review of a third party battery which I got about a month ago, PT-D-LI90 for Pentax K-7 camera by DIVIPower.
Here is the battery:
And its comparison w/ the original Pentax D-LI90 (on the right):
On the outside, the battery looks pretty well made. The obvious difference is on the back of the battery: it's rated at 7.2v 3500mAh while the Pentax original battery is only 7.2v 1860mAh. We all know that third party batteries tend to have higher rate on mAh but they actually don't last as long as the original ones.
So how does this 3500mAh battery perform? I put the freshly charged battery (which took a bit longer to charge btw, probably due to its higher mAh) in my K-7 about 3 weeks ago, it finally went flat yesterday. I took total of 1405 shots w/ this battery alone! And I used LiveView (which eats battery!) quite often, not to say a lot of playbacks and change settings on the camera. That's pretty good for a third party battery, definitely lasts longer than the original Pentax one. And this is only on the first charge. We all know that Lithium-Ion batteries would perform batter after a few round of charge-discharge. Hopefully this one will get even better after some use.
I don't know how long the battery can last eventually, only time can tell. But one thing for sure, at 1/4 cost of the original Pentax battery, I think it's really worth it.
If you still think Pentax battery is a batter option, please take mine at a discounted price (I got two original ones, but I don't mine letting them go in favor of this third party battery)
Cheers and Happy Shooting!
