Pentax D-LI50 Lithium-ion Battery for the K10D K20D Digital SLR Camera

I own 2 of these (one that came with camera and an extra one) and 4 "no name" ones. I've had no troubles with those and they only cost 25% compared to these original ones. So I think these are way too expensive as I see no benefits.

My Pentax K20D actually keeps excellent batteery life, but I don't want to take the chance of missing a great shot if it does run low. This is 'capture' insurance

Battery is reasonably priced, doesn't take long to charge up, and seems to last forever before needing recharged. I highly recommend it!

Good buying experience. Battery was exactly what I had ordered. Shipping was great, I received my order within 5 work days. Absolutely no complaints.

I've run out of juice only a few times, but having the second battery kept me going. I simply recharge the drained one and use it as the next backup. Very useful and essential if photographing away from an oulet.
