Pentax D-LI90 Spare Battery Lithium-Ion 7.2V, 1860mAh for Pentax K-7 Digital SLR Camera

I spent the money on a Pentax original battery as it appears that these actually last longer, keep their charge longer than the compatibles. I needed a pair that could be relied upon. They are quite expensive to buy, especially if you compare them in compatible batteries, but probably worth the money in the long run.

This was bought as a spare battery for a Pentax K1 Mk II. It fits that camera just fine. It holds charge for a while in the camera.

If you own a Pentax K5 then snap up these slightly lower priced K7 batteries as they are the same.

It works

It is a good product. Any third party bateries do not stand close to the original pentax one, even those with higher capacity.

Works fine, but I think it's too expensive.

I have used the batter I bought about a year ago a few times and ihas given up the ghost.Unlike the one that came with the camera it does not have a clear serial number on it.It says Pentax, but without the number I doubt that it is. Avoid.Pay more for one that is genuine and will last.
