DSTE 2-Pack D-LI50 Li-ion Battery Compatible with Pentax K10 K10D K20 K20D Camera as NP-400 SLB-1674 BP-21

Worked very well, better than my original batteries, charged quickly and the charge lasted a long time.

Great replacement batteries for OEM Pentax K20. Recently got back into photography and need replacement batteries for my old camera. I ordered these since my OEM battery would no longer hold a charge. I was not disappointed worked and did really well and held a charge for longer than the OEM batteries did even when they was brand new.

quick delivery, batteries charge ok and last as long as OEM batteries, love them

Great battery for a great camera. I got two of these to keep as spares for my Pentax camera. They charge quickly, hold a charge for a long time, and just work fine. I am very happy with this purchase

I bought this to replace the aged NP-400 battery in my Minolta 7D camera. The battery works beautifully with the camera, and has 50+% more in capacity than the original.

Good price and Fast Ship. Thank You.

Good batteries to extend shooting time of my DSLR. They seem to be good for a few hours of shooting.

Less than 3 years later, one of the two has a 2mm bulge which prevents it from sliding in & out of the camera body. I'm not going to force it and jam it to be stuck...or rupture. It's getting disposed of. The other one is still working, so I'll keep using it for now.
