Hey pentaxmz, bite ther bullet and get the real thing, if you think about the amount of investment you have in equipment, don't risk inferior batteries.
I think the Konica-Minolta NP-400's are safe. They were made for a large camera company and are made in Japan. For $10, it's nice to have a couple extra spares, especially when traveling. They don't last as long and are probably old, but I find they last long enough for a full day of shooting or about 700 images.

More often that not, third parties make many components of name-brand equipment, and in many cases, it is superior to that produced by companies who rely on their brand-name status to sell products.

Can't just call after-market batteries or other accessories inferior just because they're not "original" Pentax. I have been using an Impact as a second battery since the day I got the camera.

Just this week the Pentax battery gave me a Battery Depleted error message, which surely means it's about to get recycled soon while the Impact is still going strong. Not bad for a 1.5 yr old "knock-off" battery .

Well said--I agree, %100.

The 'real thing' in my city is $99.00! No battery of this type is worth $99.00!

Some of the other contributers of this thread have certainly proved this.

I am still ticked that the K20D battery grip doesn't support the ubiquitous AA battery. Try being in the field (far from North America) and needing power. I suppose I could rig up something using the external DC power connector BUT... they had a good thing with the MZ-S BG-10... why did Pentax mess that up?

Interesting....

I found this battery grip which seems to support AA batteries. That is, if I understand the poorly translated English text.

Battery Grip for Pentax D-BG2 K20D K10D Samsung GX-10 - eBay (item 110313581386 end time Jan-15-09 21:53:32 PST)


I wonder if it is any good.

In another thread I tested two of the Chinese replacement batteries for my K20D. While the mAh rating printed on the battery was overstated (by a rather surprising 25%) the batteries held a consistent voltage over its entire power curve. That is just what you would expect from a battery.

I will be getting two more Chinese batteries shortly (different rating and I suspect different manufacturer) and will test them the same way. I will post my finding here.

I should have added that the battery thread is in the Accessories section. https://www.pentaxforums.com/forums/pentax-camera-accessories/44194-cheap-mad...rth-price.html

My feelings exactly. The problem I found with some of these batteries is that they have a very low number of charge cycles; in fact, less than 1/2 the charge cycles of a name brand.

Any suggestions where to get a good price for k20d dbg2 grip in ebay?

Do you guys recharche batteries only when they are completely drained or they can be charged at half way, for example, without loosing capacity ?

LiIon batteries should never be completely drained, it will shorten their useful life. That said, your camera cannot completely drain them. You can pull them out of your camera and recharge them whenever you like with little or no ill effects.
