RE: Third Party Batteries
From: Brian Walters I'm sure this has been discussed before but my memory isn't what it used to be Is anyone using third party batteries in their K-7/K-5? The prices are "considerably* lower than the Pentax branded ones but I don't want to blow up my new camera. No experience with K-7/K-5, but I never had any problem with generic NP-400 batteries in the K10D & K20D. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: Third Party Batteries
Thanks, everyone for the feedback. I thought about ordering via Amazon as I still have some credit there from a gift card last Christmas.

Re: Third Party Batteries
Igor, I am not talking about the declared power rating of the batteries. I am talking about the actual experience in terms of my regular shooting and the moment when I had to replace the battery. I never _measure_ these things. I just use my gear and (being immodest here) being pretty observant person, I notice things such as when I have to replace my camera batteries.

Re: Third Party Batteries
I can't say anything about third party batteries in the K5/7 but I've been using a flashpoijnt battery in my K20D. It gives about 1/2 - 2/3 the number of shots as the OEM battery at about 1/4 the price. So it makes economic sense.

Re: Third Party Batteries
Argh, sorry to hear that, Paul. I think I had over-charged by placing an already charged battery back on the charger... whoops. But, I would keep an eye on it & not hesitate to send it in for repair -- my camera started out with a few random issues like you describe, which then quickly degenerated into full-on non-functionality. I also found, like you, that a somewhat drained battery was less likely to create problems. I thought it was interesting that putting a "problematic" battery - the one that was in the k-5 when it was flopping -- into the k-7 did not produce the flops in that camera. That's when the k-5 went in for service. Luckily, it was a quick trip to Arizona & back -- they knew exactly what the problem was, had seen it before, I gather... Since then, I have used the same batteries in the k-5 without issue. Also, I don't worry too much about leaving the batteries on the charger beyond the charging time... maybe I should... but I haven't had any recurrence of the flops since getting it back from service.

Re: Third Party Batteries
Happened to me as well. I charged both of my k-5 batteries -- grip and camera -- last week. I usually charge just one, and then get the other next time. I left each of them on the charger for a couple of hours after they were fully charged. Right after charging the second battery, I tried to use the camera, I experienced the mirror-flop disorder. At least that's what I assume it was. The camera kept making a clicking noise when the shutter was pushed and wouldn't function. I switched off the trip, and the camera started working intermittently, so I turned on preview and left it on for a few minutes. After that it worked fin, and I was able to switch the grip back on. I'm going to go back to charging only one battery at a time and taking care not to overcharge. Or if I do charge both at once, which I have to do for big jobs, I'm going to make sure they don' t spend too much time on the charger, and I'm going to leave the grip turned off until I've logged a few shots.

Re: Third Party Batteries
I have two third-party, and two pentax, batteries... they seem to work the same. Once upon a time, my k-5 had mirror-flop disorder... in which the mirror would randomly and repeatedly actuate, rendering picture-taking impossible. (It was almost like blowing up!) There is some speculation that could be initiated by an over-charged battery disturbing the electrical ecosystem in the camera... I have no idea. It was never a problem in the k-7. But, I'd caution against over-charging the batteries... :) -c On Fri, Jun 1, 2012 at 6:58 PM, Brian Walters wrote: > I'm sure this has been discussed before but my memory isn't what it used to > be > > Is anyone using third party batteries in their K-7/K-5?

Re: Third Party Batteries
When I bought the K-5 from B&H, I got the Pearstone branded extra battery. It's listed as 1700 mAh vs 1860 for the Pentax brand, but otherwise seems to work just as well...and it's half the price of the Pentax. -p On 6/1/2012 6:10 PM, Larry Colen wrote: On Jun 1, 2012, at 3:58 PM, Brian Walters wrote: I'm sure this has been discussed before but my memory isn't what it used to be Is anyone using third party batteries in their K-7/K-5?
