Re: K3 battery life
OEM battery. However when I've bought third party batteries I've made sure to only purchase units with the same terminal voltage and capacity as they will likely be less trouble when used in a dual battery configuration.

Re: K3 battery life
I didn't realise that the K7 was similar, the K3 has been pretty consistent, I've now done quite a few shoots with 1300+ images captured on it and never depleted the battery fully. I had it lock up once when I had the OEM battery in the body and a 3Rd party in the grip but since I have changed to two OEM batteries it seems to be behaving, though that could just be coincidence.

Keeping track of battery life
I'm mildly curious about how many photos I can get with a charge of the battery, and have decided that the easiest way to keep track is that when I change batteries, I take a picture of the one I just took out. I'll then put all of those pictures in a set and look at the file numbers.

Re: Battery life on K10D
I downloaded photos to my computer from the SD cards this AM. Strange things happened with my K10D. I put the card(s) back into the camera to delete the images. The light went on briefly, then all was dark...no battery juice. I went upstairs and got battery #2 (Pentax) with the same result, no battery juice. I went up and found the 3rd battery and had the same result! Now I think maybe I've got a charger problem. I take all the stuff back upstairs, find the charger, and try charging. #2 battery lights the red charging light for a fraction of a second, then goes out. #3 spare does the same thing... :-( I try cleaning the contacts on the battery. (nothing fancy, just vigourous rubbing on my pants) Still no improvement... So I try charging the original battery that quit. It charges for about 10 seconds then quits, the red light goes out. Puzzled, I try cleaning the contacts and re-inserting the battery. This time I push the battery down into the battery well a couple of times. Now everything works just fine! When you tell me I've got 310 minutes of playback on a battery charge, I think something has been going wrong and my battery is dropping out early. This could explain my shorter life. I've got to send the K10D in anyway for the SD card door (I broke it, dumb!), so I'll have Pentax check it our for me. It is a bit unsettlilng as I want to take photos of the Cherry Blossoms in Washington, DC this weekend. I'll have to bring the Ds as a back-up. Regards, Bob S.

The only way I can think of for the camera to start re-using numbers is if the battery died (so the internal frame count was lost), and the card that was in the camera when a fresh battery was installed (or the first card that was insrted after the battery change) was an older card that still had images on it. In that situation the camera would reset the internal frame count to one more than the highest image number that it found on the card; it would have no way of knowing that there was some other card containing higher-numbered images. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

I think i reported about 400 when mine died a week or two ago, but i misinformed you. It was more around 280. However it was the first charge and battery was in the camera from mid December to second week of March, so it probably lost a bit sitting around at times. I also wondered if it might pick up, as my D200 batteries didi this at first, low number of shots , but after a few charges are producing about double when used and abused, not used a bit and then sitting.

Battery life on K10D
Saturday I did some little league shooting and thought I would report my findings. I shot 1304 shots on one battery - all AF-C and very little chimping. The battery is a Lenmar 1500mah and the camera meter still says full - don't know how used it is, but did just fine for this shoot. Never even got to my other two Pentax batteries.

Re: Battery life on K10D
I'm getting 800-1200 exposures per charge on a pretty reliable basis with the K10D, using the Pentax supplied battery. The Impact and Konica Minolta batteries I have as well seem to last about the same amount of time. It varies a bit based on what I'm doing ...

RE: Battery life on K10D
FWIW, when I designed a voltage regulator a couple of weeks ago so I could run my istDS off of a 9.6VDC NIMH battery pack, I found the flash is the main power hog, and the LCD is the second most power hog. Not news I guess, but if you want the longest possible life on a single battery charge, these have to be minimized in usage or better yet turned off. jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Godfrey DiGiorgi Sent: Tuesday, March 27, 2007 8:29 PM To: Pentax-Discuss Mail List Subject: Re: Battery life on K10D I'm getting 800-1200 exposures per charge on a pretty reliable basis with the K10D, using the Pentax supplied battery.

I bet since they are intermittant and are only really just low power dc motors essentially, they would not be much of a factor unless you left them on continously for some reason.

RE: Battery life on K10D
there are many many different types of battery chargers on the market today of widely varying sophistication and automation so I would say that its not quite as simple as that. Many actually stop charging completely when the charge light goes out, so even if you leave it on longer you are not getting any more charge. For NIMH batteries, What I have settled on is two rate manually controlled self designed chargers, w/ fast and trickle charge rates. I use the fast/high current value @1/8C with a cutoff timer so I dont overcharge but I can set the total charge time to whatever I need depending on the mA Hour rating of the battery being charged. I then use the trickle charge setting/value @ about 1/40C but don't really do a typical trickle charge (always charging), I only trickle charge mine for only one hour a day via another 24 hour power timer. This method works well and doesnt stress the batteries and I have fully charged batteries always ready to go without leaving them charging all the time or having to keep recharging batteries that self discharged because they were not trickled or full charged recently. The only caveat, and it can be a big one, is that this method really only works well with batteries fully used up before fast charging again, if not sure or I know only a little discharge has occured, I just put on trickle for 24 hours continuous rather than use any fast charge to be safe and not overcharge the batteries. Works for me, your mileage may vary of course. jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Godfrey DiGiorgi Sent: Tuesday, March 27, 2007 11:43 PM To: Pentax-Discuss Mail List Subject: Re: Battery life on K10D On Mar 27, 2007, at 7:10 PM, Markus Maurer wrote: Is this third party charger only for the Pentax K10D accu or does it work with other accu brands as well?

K10D expected battery life ...
Oh yes: just noticed that I was on exposure 894 with the K10D, I charged the battery once when I opened the box. The battery indicator flickered to the half indication briefly, then returned to full indication afterwards. I'm expecting a full charge will normally net 1000-1200 exposures. Will report when it can no longer power the camera. Godfrey -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Re: AA lithium battery life
Paul, I'm getting about 1000 exposures on a pair of CRV3s, with very little flash use and very little chimping. Since AAs have less capacity than CRV3s, and since most people chimp more than I do, 2100 exposure for 3 pairs of AAs seems about right. $1 apiece is a great price.

Of course MTBF (mean time before failure) like most statistics has no meaning when applied to an individual camera. Nor does it say anything about when the shutter will wear out as that is controlled a lot by how often the shutter is serviced.

RE: *-ist D and NiMH battery life
Id hate to think what it costs to have the shutter repaired/replaced in a DSLR but it does bring up a good point, exposures on a DSLR are not really free. although the cost per exposure is very very low, I wouldn't want the premature downtime needed to have the camera serviced due to a worn out shutter due to excessive wasted over shooting. Not only that, the more you over shoot, the more time you waste reviewing and comparing all the exposures later...

*istD Battery life and 85mm FA*
Shooting in the cool of the evening recently with the istD I changed from the 24-90FA to the 85mmFA* to keep my shutter speed up.. (already at iso3200). Disaster!... there was no indication of aperture... and the lens refused to autofocus.. changing to the 50mm 1.7 allowed me to continue and indeed I have taken around 50 more shots with the 50mm and the 24-90. Though both the 85mm and a recently acquired 24mmFA* refused to function. This morning the battery meter showed low for the first time and autofocus failed with the 24-90. Well, as you can probably guess, changing the batteries has restored full function even with the 85mm.. So it would seem that the mechanisms of the larger FA* lenses require quite a bit more power than the lesser optics to the point where they act as an early warning of battery life...More glass, heavier gearing I guess. OH and how many shots has my first set of batts given? A quick count of the saved files gives a figure of around 770, not many with flash but the fisrt 100 or so with an 340Mb microdrive, the rest with Lexar 40x, and I do not use the review screen that much. A set of lithiums costs around UK £15 so that's a bit less than 2pence (one centUS) a shot. Pressing the shutter on a *istD is a pretty cheap thrill!!!Tom A Yahoo!

Battery grip FG/ battery life
I just had a curious thing happen with my battery grip. My 5n has been on a break for a couple of weeks, after shooting about 3 or 4 rolls. On a couple of occasions, I've forgotten to switch it off as well, sometimes for just an hour or two, once overnight. Anyway, I was quite disappointed to see the battery indicator flashing so soon, so I removed the 4 Energizer e2 alkaline batteries (battery of choice, usually long lasting, and Big W has packets of 8 going for around AUD11, maybe USD7.50). Quite amused by those inbuilt battery life testers, I picked up each (presumably dead) battery and pressed the designated points as hard as I could to see if I could get a green mark to light up, and the strangest thing- the first battery was dead flat, while the other 3 were full or very close to it! They were all from the same batch, straight from a new packet into the camera. Would anyone have an idea of how this could be possible? I thought they were all in a serial circuit.. Other things I'm considering- for a while I actually removed the grip from the camera just for storage reasons (leaving the batteries in), could that have contributed anything? Also, I used the 360fgz for a few rolls (not sure how much this would factor in, since it does use 4 batteries of its own). Curiouser and curiouser! Any thoughts? Ryan

Re: ME Super battery life

Veering rapidly OT: Battery life
Hi, Timothy Sherburne wrote: I'm not sure of the exact demonstration Boris mentions, but he refers to either gas-powered microturbine or fuel cell technology. In either case, the fluid is simply methanol or a similar fuel. Fuel cells have been around for some time but have been slow to reach the marketplace, IMO because there's little incentive for industries to change to a technology that has a very low consumable cost. It's also an expensive technical feat to productize these concepts. Fuel cells are relatively uncomplicated and environmentally friendly; nuclear power and chemical batteries are, of course, not. Fuel cells and suchlike have been around for almost 50 years. Given the market potential for such devices, there are two possible reasons for them not appearing. One, there are (presently) insurmountable technical problems. Two, vested interests are preventing development. Regarding one, the simple fuel cells using methanol and hydrogen have had enough development time for them to have evolved to the equivalent of a 50megapixel camera. As far as I can tell, they are still having difficulty at normal size generating enough energy to drag a car body around for a reasonable time. Micro applications are complete non-starters. More and more esoteric and hazardous fuels are being applied and yet there is still no functional cell available for purchase. I find the idea of microturbines to be both funny and frightening. To be functional, a microturbine will have to revolve at speeds in the hundreds of thousands of revs per minute. By the time you have associated the relevant cooling and power creation systems, not to mention the fuel tanks, they are non-starters, if you will pardon the pun. Also, the thought of something spinning and steaming away in my jacket pocket like that fills me with trepidation. The shielding required to deal with potential catastrophic and explosive failure only adds to the problem. My (admittedly intuitive) conclusion is that the difficulties involved in successful application of this technology are nowhere near solved. In fact, it seems that each new (near) resolution only creates more problems. Regarding two - who knows? Certainly the petrol companies have bought and applied for many patents in this area. No technology is environmentally friendly. Maybe fuel cells are, relatively, but I think that there has been absolutely no research on this matter. In the absence of evidence to the contrary, I stand by my belief that power supply is one of the biggest inhibitors for photographers to move to digital and that it is likely to become the biggest in the relatively near future. I would be very careful of believing the statements of sources that can come up with the following twaddle. Source: www.smalltimes.com In fuel cells big and small, hydrogen atoms enter at the anode, a negatively charged electrode, where a catalyst strips them of their electrons. These electrons provide the current that powers the device that the fuel cell is connected to. Meanwhile, the ionized hydrogen atoms travel through an electrolyte, essentially a screen that blocks loose electrons from flowing to the other side of the fuel cell and mucking up the chemical reactions. These hydrogen ions end up at the cathode, the positively charged electrode. Oxygen from the air also flows into the cathode, where it combines with the electrons returning from the device and the hydrogen ions. The resulting waste products are heat, carbon dioxide and water, which micro fuel cells often burn off as steam. Just as a comparison: State of the art technology, from the same source as above. Berkeleys steel mini-engine currently runs on hydrogen and can keep a bicycle headlight lighted for two hours on a shot glass of fuel My Coleman lantern can go for about 14 hours on a pint and puts out considerably more light and warmth. mike

That is, they will use less power and batteries will increase in capacity somewhat to give you a _possible_ doubling of useability. Unless, of course, the number of bells and whistles is multiplied by the marketing departments to justify selling you this year's model, in which case all bets are off. This, combined with the high cost/short life ratio, lack of (or different manner of) definition and fragility of digital cameras, plus the long, complicated (and yet tedious) process before one has an analogue copy in one's hand, leads me to seriously doubt that many people who enjoy photgraphy as it is will be easily moved to the digital arena.

Re: Battery life (was: PB 1400 upgrade info)
I'm running a PB1400 with the Sonnet/333, 64Mb RAM with 9.1 without too many problems. The (original) battery was giving me max 15 mins life, so I splashed out on a new one - which has given me 2 hours again. Batteries don't have unlimited life, but is there a way to prolong them? The laptop is used mainly on the power lead, so should I leave the battery in all the time even though it's not being used, or run the laptop off the battery from time to time, and have it regularly recharged. I've occasionally used the Battery Recondition utility as supplied. Hi Wallace, AFAIK, the 1400 requires the main battery to be located in the bay for the PRAM battery to charge, hence using the PB on AC from the wall without a main battery in the bay will result in the PRAM battery eventually going flat, and possibly producing spurious problems, possibly even the machie refusing to boot. Very definitely the 1400 should be used purely on battery I would say at least once a month.

Re: battery life in PZ-1

I've found Vartas and Sanyos to last very long, Duracells to be about the worst. That 50 rolls figure is a mixture of 36 and 24 exposure rolls, so you mileage will vary - but 7 to 8 souds very low to me, unless you are using AF, powerzoom, and flash a lot.

Using the built-in flash is the number one reason why the battery was drained fast. Switch off power zoom and do not use AF whenever possible also maximise the battery life significantly. my other question is, has anyone actually built some kind of adapter that uses AA batteries? i was thinking of making a very small hole in the battery cover to pass the wires and then hanging 4 batteries at the bottom somehow. does anyone have any concrete ideas on how to hold the batteries at the bottom and make sure that the contacts are made inside the battery compartment? would soldering wires to an old battery contacts do the trick?

RE: battery life in PZ-1
Hi Gaurav Welcome to the list. NICE CHOISE OF CAMERA No, 7-8 rolls is fine. As you use the flash much. YOUR CAMERA IS NOT DEFECTIVE. The trick is not to use it too much. I used up a lot of batteries when my PZ-1 was new. I guess you play a lot with it :-). Try to use it only for fill in purposes. Today I'm changing the battery 4-6 times a year. (I shoot hundreds of rolls) I always carry a spare or two. Try to order ten or more from a mail order company - or surf the internet - you'll find a good bargain somewhere. Someone actually has made a homemade battery adaptor (It's not made by Pentax, I think). Unfortunatly I don't think the old PDML threads are available anymore, I'm afraid. I don't think NiCads can be used. Best Regards Jens hi! i subscribed to this mailing list today after reading quite a few posts on pdml.net. i am just a beginner in photography and hope to gain from the discussions on this forum. i bought a used PZ-1 and now realize that the 2CR5 battery lasted only about 7-8 rolls. isnt that too less? i didn't use the flash on more than 15-20% of the shots. am i doing something wrong? or was the battery little drained when i bought it? my other question is, has anyone actually built some kind of adapter that uses AA batteries? i was thinking of making a very small hole in the battery cover to pass the wires and then hanging 4 batteries at the bottom somehow. does anyone have any concrete ideas on how to hold the batteries at the bottom and make sure that the contacts are made inside the battery compartment? would soldering wires to an old battery contacts do the trick? thanks in advance!! gaurav - This message is from the Pentax-Discuss Mail List.
