Helping a friend!!

Hello There!!


A friend of mine has a K10D, bought in new 4 years. For about the last 6 months has been stoped. He picked it up, pressed "on" and nothing...
The only thing is a empty battery sign flashing...we tryed to charge the batteries full, he has 3, so 2 of them where inserted on the charger, it flashes the red light and shuts down. The third one, charges full for about, six hours, it's new, so we inserted it on the camera and the same thing happens, the empty battery symbol flashes and nothing else happens...


Can anyone help me and a friend out?? Please!!!

You might try cleaning the battery contacts in the camera. This can be done with a bit of rough cloth or a pencil eraser. Sometimes just a bit of corrosion is enough to cause problems. If that does not help I suppose a trip to the repair shop would be next.

Thank you for the help Jatrax!
I'll try cleaning the battery contacts on the camera and see what happens, because going to a repair shop for Pentax in Portugal, isn't possible because there are none...

Once again thank's for the idea!!!

Other than contact corrosion, I would verify if the batteries are still good, or if the charger is broken. I had broken third party battery that behave like yours.

Thanks, in fact the only battery that seems to be working well is a third party one.

Well, there must be something wrong, with the camera, since i've cleaned it up, i charged the battery and seames to be ok.
The dilema now is what to do with the camera since there is no Pentax representative in Portugal, the nearest is in Spain.


My friend the camera owner, is thinking about trowing it away.


For me, it should be fixed, if only the where a type of list of errors, i was thinking about opening it up and try fixing it my self... i just don't know,...

Think about it.


The camera was working fine and was put down and not used for 6 months. Cameras don't fail just because you haven't switched them on for 6 months, the camera is probably fine.


The 2 original batteries don't take any charge this confirms the batteries are faulty.


The chance of both the batteries and the camera both developing faults at the same time is very low. Batteries are a weak link.


This leaves the third party battery that seems to be working. You cant assume it is, you know the 2 original batteries are faulty so you must assume the third party one is as well until proven otherwise.


I recommend taking the camera to a shop and asking them to try a new battery in it, if they have one with at least a part charge the camera should turn on and work.


If the camera turns on with their battery they have made a sale.


Don't strip the camera and try to fix it, for one thing you may be taking a working camera and destroying it, for another do you know how to trace a fault in a camera.


Check the batteries not the camera.

All batteries eventually die, and some don't show any exterior signs - leaking, bulging.

Check the batteries under load - even in Portugal there must be someone with a simple volt meter.

Hummm...yap! I think we've got at least one volt meter, around here!! eheheheh

Thanks a lot wildman!

Batteries are nasty things. Even if the open circuit voltage is OK, under the load of starting the camera the voltage may drop enough due to internal resistance that increases as it ages that it will get a low voltage alarm internal to camera and there is the effect you see. Can you try a battery of the same type with the camera.


Does K10 use AA - either Alkaline or NiMH - that might be a practical way for you to test if it is the camera or battery without too much expense or delay - and AA batteries would be useful for some other purpose for you.

Unfortunatelly, the K10D does not use AA type batteries.
But i can check the voltage before and after putting them on the camera and see if there is a diference...i supose...

Unfortunately the phenomenon of internal resistance of a battery con only be measured when the battery is under load because it is an effect associated with the delivery of power.

Googling k10d and batteries shows others experience of buying third party batteries off ebay.


One user says he gets 500 shots from a genuine pentax battery but only 5 shots from a third party battery. This is an extreme case but it does suggest that this third party battery you have although new is still suspect if third party batteries can be this poor.


I would still assume its a battery issue and try to check the camera using a known good battery.


I don't see an easy way of testing the battery and is it worth buying a battery simply to discover the camera is indeed faulty and you just bought a battery you cannot now use.


No camera testing facilities in the whole of portugal means your stuck.


One option might be to bite the bullet and buy another third party battery if theyr cheap enough but your likely to end up in the same position.


Another option might be to write the camera off and buy a replacement off ebay that uses the same battery k200 or whatever, I don't know which models do.


The chances are it will come with a battery, and you then have 2 cameras in which to test batteries and a backup camera. If your third party battery fails in the second camera the battery is the problem, and if the k200 battery works in the k10d the camera was fine.


Its no solution but at least you know what was wrong and the money hasn't been wasted, and maybe you can sell one of the cameras on later after the test if you don't want a second body.


I cannot believe that in the whole of Portugal there is nobody capable of telling you that either a battery or a camera is faulty. That's like having no tv repair men or no car repair garages.


A camera shop surely should be able to tell you the battery works in your camera if they want to sell you a battery, maybe its worth asking them to test a pentax battery in your camera before purchase, and if pentax batteries are truly much better than third party ones maybe that's worth doing.


On the other hand, a drive to spain if they have a camera repairer there might be worth it, you get a mini break and some pictures out of the deal. I really cant think of anything else to suggest here. Id probably go for the option of buying another k10d off ebay or a similar camera that comes with a battery and it must use the same battery model, and keep it as a second body for testing or in case the first k10d fails down the line.
