Re: K3 battery life

[Rob Studdert]

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.

Was that a Pentax or after market battery? I've got one of each and it will 
be interesting to see if the After market battery was worth the money

Hi Team,

Just thought that I would mention that I managed to shoot 1578 shots
on the one battery last night, there was still some power left in the
grip battery and the body battery was unused.

That's shooting with the rear screen off, top LCD illumination off,
single point AF on the back button and JPG + RAW on a 64GB/95MB/s
card. Not too bad.

Re: K3 battery life

[Rob Studdert]

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

[Larry Colen]

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.

I figured that I'd mention this in case anyone else wants to try it also, that 
way we might get some real world data on Pentax battery life.

Hmm, I never erase a card (on the computer that is).

I put it in the camera and then format it  ...
Sofar it has always picked up the correct numbering.

Must have been a combination of card changes 
and battery changing I guess ...

The camera creates a new folder on the card. I've changed a filename

It's hard to say, but I rather doubt it would over-write images; I think
the camera checks a card first, and ensures that the next image number
it will use is larger than any image numbers it finds on the card.

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.

I missed it in the camera documentation as well. I picked that tidbit up 
from another photography forum that I am on.
One of the things in the service menu that was available prior to the latest 
firmware revision is something related to the card door and power down. I 
didn't play with it, but I suspect that this is a switchable thing.

That has been my habit as well. I expect the filename conflict happenned 
when the grip battery went south and the camera switched over to the in-body 
battery. I wouldn't have noticed except that I tried to dump three cards 
into one directory on my computer later, and got a filename conflict at that 
time.
Scary, if it is possible for this to happen, is it also possible that the 
camera might overwrite it's own files while shooting? Or would it start a 
new directory on the card?

It is possible that the broken door is causing your problems, isn't it?

I thought that was one of the things that Phil on DPReview complains  
about with so many different models of camera - that the camera shuts  
off right away if you open the memory card door, even if it is in the  
middle of a write operation.

Re: Battery life on K10D

[Bob Sullivan]

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.

According to the manual the battery is capable of 310 minutes in playback

After reading this I have worried a lot less about using the LCD. 

My rough estimate is that about 20% of my battery consumption is chimping,
when I chimp. I can live with that.

I do a lot of chimping and histo. Pretty much every shot, so that

Can confirm that :-)

I ran out of the first battery (in the body) somewhere arround 850,
then replaced it by the one that was in the grip, and that ran out
about 100 images later.

So that gives me roughly 450 shots per battery.

That said, this was the first charge for both, and and i do a lot 
of chimping and checking histograms. And of course I also
played with the menus a bit when I just got the camera ...

So I expect more images from the next charge :-)

Re: Battery life on K10D

[David J Brooks]

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.

It's a CTA charger for the NP400 battery: here's a link to it on  
CompUPlus.com.
   http://tinyurl.com/38sag3

I usually stick the battery on charge and leave it sit on the power  
for a while after the charge light goes out. Typically, the charge  
light goes out when the battery has achieved 85-90% charge on most of  
these types of chargers.

RE: Battery life on K10D

[J. C. O'Connell]

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.

RE: Battery life on K10D

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. Its
an estimate, I didnt test those features, the istDS
doesnt even have AS to test. I doubt anything else
is going to be even close to the full power
flash energy consumption.

No idea about that. Anything that keeps the LCD illuminated or status  
display illuminated will consume battery power to a greater degree  
than nearly anything else, however.

Perhaps you are not charging the batteries all the way? or have a  
less than perfect charger? I use a third party charger, from Impact  
again, rather than the Pentax charger because it plugs directly into  
the wall and also takes a power connection from the accessory jack in  
the car.

RE: Battery life on K10D

Is this third party charger only for the Pentax K10D accu or does it work
with other accu brands as well?
I use the Pentax charger but I think it never took  3 hours as written in
the manual for a complety loading but maybe 2.
I can't do anything wrong with it, when the red charging light goes off, the
battery should be fully loaded.
But I will have to see if the batteries last longer after some use...
Thanks and greetings

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.

I'm really impressed with how frugal the K10 is regarding battery 
consumption. I did most of both of my doggie shoots on one battery. With 
several short chimps to check histograms, and a few longer ones to show

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.

Re: AA lithium battery life

[Rick Womer]

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.  Let me know if it's still
that low--I'll switch to lithiums for everything!

much battery life. I believe I'm paying just over a buck each for the  
batteries now when I buy them in quantities of 16 or more from  
Battery Central. I'm not sure about that price, but I'll be buying  
another 16 this week, so if anyone cares, I'll let you know.

Battery Life

[Trevor Bailey]

G'day All.

I was searching for data on battery life and came across this site.

http://www.users.bigpond.net.au/vk3yng/batteries/aa_battery_comparison.h
tm

Some interesting results.

May be of interest to some list members.
Hooroo.

Good point. 
More pictures generally means just that.
It does't necessarily mean better pictures.

a worn out shutter on a 3 year old *istD will not be worth replacing. you
would replace the entire camera, even if it is just with another *istD.
however, i doubt that the camera will still be in production.

RE: *-ist D and NiMH battery life

[Jens Bladt]

I know. I'll try to learn to shoot a little less. The reason I'm shooting
this much is, that I use my camera at work some times. Image editing after
the shooting takes too much of of my time...

RE: *-ist D and NiMH battery life

[J. C. O'Connell]

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...

I kind of though shutter MTBF was rated at about 50K cycles on amateur
cameras 
and 100-150K cycles on serious pro cameras. 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. I would guess a

I wouldn't be surprised if the recent reductions in top shutter speed
and flash sync speed (1/4000th and 1/150th on the ist-D) aren't related
to making the shutter's moving parts beefier (heavier and therefore
slower) in anticipation of people taking a lot more shots with digital.

I am wondering how you don't keep bumping into things, with that camera glued to your 
face 8-)

Looks like you will be buying a new one, or at least getting it serviced [unlikely, 
because that should read: completely overhauled, with a new shutter assembly], within 
three years if the 100,000 shots estimate is correct.

*istD Battery life and 85mm FA*

[Tom Addison]

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

Ryan,

This is correct.  I always have a battery tester on hand when I shoot.  I
have found, time after time, that when I check the four batteries that have
shown as depleted on the unit it is almost always only one of them that is
low.  I have been able to reuse the other three with no problems.

I actually came across this by accident.  A friend was moving out of the
area and had a bag of batteries to be disposed of at the military base.  I
told him I would take care of it.  Just for fun I went through them with a
battery tester.  A great majority of them were useable.  As a matter of
fact, I still have quite a few of them still in my refrigerator.

As for battery storage, I usually remove batteries and keep them band them
together for use later.  This minimizes any chance of battery leakage - but
then again I have quite a bit of gear that it may be a while before I get
back to an item.

You could have had a dud right out of the box.  It's not a common

My ME S and ME cameras do not consume battery power except when making an
exposure or taking a reading. The latter times out in about fifteen
seconds. There is no "meter switch". I think battery life is in the
thousands of eposures. I haven't changed batteries in several years.

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.
"Berkeley’s 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.

And 50 years ago, in the UK, they said that nuclear power would
be so cheap it would not be worth charging for it.  That was
before an unknown number of people were engulfed in the
radioactive plume from the Sellafield fire in the late 1950's. 
The idea of portable nuclear power supplies sank without trace.

This, combined with the high cost/short life ratio, lack of (or

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.

Battery Life SF-10

[Bgpentax]

  Hi Guys...
 Does anyone have first-hand experience on the battery life in an SF-10 ?
 I picked-up a used one in "mint" condition , put in a new Duracell 2CR5 
Lithium
 and proceeded to shoot about 8 rolls of 24 exp...I used auto-focus 
extensively
 and the pop-up flash about 20% of the shots. I usually leave the main switch
 "ON" while walking around but switch to "OFF" when done shooting. The pop-up
  stays "DOWN" when not used. When I went back to the camera after a 10
  day idle period, the LED's & LCD's light but the drive would not advance 
the film.
  I put the 6V battery on a multimeter and it read 3.4V ...Is this typical or 
do I
  have a short...
   Thanx
Bob G.

RE: battery life in PZ-1

[Jens Bladt]

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!!

REPLY:
Depends. If you use AF, Power zoom and flash the batteries won't last long. Power zoom 
is particularly bad for battery life. Also, the Z-1p uses batteries when using long 
shutterspeeds. My batteries have lasted as short as three rolls.

It's easier for newbies if you give them the  www.micro-tools.com  url.

They have nylon, molded and machined, slugs to replace the 2CR5 battery 
for bench work. They have pigtail leads and would do marvelously for 
designing a pocketable case that holds some Lithium AA's, or at minimum 
get your 2CR5 in there for warmth in cold weather shooting.

Do watch out for overvoltage, current capacity, etc. There have been 
previous posts about this, including but not limited to the engineer who 
was (sniffle) making us a battery holding vertical trigger equipmed 
machined aluminium base and grip for the (P)Z-1(p).

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.

You can find two similar adaptors at www.fargo-ent.com. Personally, I would 
not do this. But then I paid about USD3.9 for each 2CR5 only.

Re: battery life in PZ-1

[Mark Cassino]

I have a Pz-1p and can easily get 50 rolls to a battery. I
seldom use autofocus or the built in flash, so that probably extends
things. Battery brand can have a really big impact.  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.  But if the batteries were old or
improperly stored before you bought them
