Hi, Have K200D and in the past few months am having problems with batteries....have always used energiser lithiums successfully but now it keeps bringing up the battery depleted message. If I switch off and on again shows full battery but if I take one or two shots it shows depleted once again. Does the camera need to be sent for repairs?many thanks in advance.

Stan,

If not the batteries, then you have to look close into the battery holder. All contacts should be clean and shiny. Eventual you can clean contacts with a dry cloth. Never use a sharp tool.
But still.
Do not use alkaline batteries unless it is absolutely necessary. In some cases, alkaline batteries may have a shorter service life than NiMH. Alkaline battery performance is limited, especially at low temperatures. The use of NiMH batteries is recommended.
Never use manganese (Zinc-Carbon) batteries in your camera.
Always be sure the battery is charged and suited for your camera. Check contacts of the battery and in the battery compartment of your camera. Dirty or oxidised contacts can be cleaned with a dry cloth. Never use sharp tools to clean contacts or anything in or on your camera.
Always charge the battery before using it for the first time, or if you have not used it for a long period. 3 months is a very long period.
Also check if the battery door is closed correct. Most cameras do have a switch connected to the battery door. If the switch does not work correct, it could be you can't switch on your camera.
If you have a multi meter, you can check your battery. After charging the voltage should be higher (few tenths of a volt) than the voltage printed on the battery.
If the voltage is slightly lower, you know thee will be not enough left when the battery needs to deliver some power.

normally cost $199 is the dc-dc converter circuit , but try this put new batteries or the original Pentax battery and see what happen , U can update the firmware in the camera maybe that fix that problem .

Lithium batteries have some circuitry built into them to keep them from exploding if they are overcharged. Ridgid lithium batteries are having some issues with that circutry right now. I have 10 ridgid batteries that have gone bad within a few months. Almost all ridgid tools have the lifetime service agreement, where they will replace the batteries. Hopefully you filled that out when you bought it. You may have some luck asking nicely at home depot to see if they will exchange them for you. dont forget, ridgid tools have a 90 day no questions asked return policy at home depot.

What type of batteries are you using?
I have only found ONE battery that is worth buying for a digital camera, any make or model. I've always had HP cameras, but my last purchase was the Canon A1100 IS. It is amazing, but all that power makes it hungry too.

I have had nothing but success with the BLUE Energizer LITHIUM batteries. They run about $5-6 for a two-pack or $10 for a 4-pack at WalMart. We get an amazing amount of shots out of these. The only time I totally drained them quickly was when I took several movies. I always date the batteries with a sharpie to see how long they last. I regularly get from 1 month to 3 months, depending on the quantity of shots.

Other batteries, even alkaline, are useless. I tried the Duracell copper tops, and got maybe 8 shots before they died! : P
So, we now only buy the blue energizers, with no regrets at all!
(And the neat part? Those blue batteries have more juice left after your camera too. Once they are not powering up the camera properly, they can be used in other things that take AA, like small flashlights, etc, and it can still power those items as well. We have a beard trimmer that I never have to buy batteries for - I just use the used camera batteries and we get even more use from them.)

Truly, I am a loyal BLUE Lithium fan for life.

This is a common problem with some Pentax cameras. The only solution that people have found is to turn the camera on and off until the battery indicator show a full battery. You can go to pentaxforum.com to read about others with the problem.

I've had a similar problem with my Z1285.

The problem is probably weak batteries. The Z1285 requires really good batteries. Standard alkaline batteries don't last very long, perhaps a few dozen shots, less if you are using flash.

I've had success using lithium batteries, not the rechargeable type, but the disposable lithium. Specifically, the AA4 Energizer Ultimate Lithium.

Hope this helps.

Hi,
Use hi power battery (Energiser Ultimate lithium for example). Change position of shooting to Manual and disable the flash. The full power now will be available to unlock the shutter and your camera is back in order.
If still not working keep it at a temperature over 23 Celsius and try the same. It will start Magic and you will be happy you spent 9$ for those batteries that last over 1000 shots
Regards,

The battery charge indicator is temperature sensitive. If you switch off and on again, do you still get the low battery warning? Have you tried with a second set of batteries - either rechargeable, or lithium or alkaline. I would do this in a warm room, and try it with new alkaline cells. You lose some of the functions, but if the indicator say charged, and you can take a shot, then the body is OK.
Call me old-fashioned, but I use a multimeter on all NEW batteries to make sure they are functional - I bought a card of cheap LR44s and the first three were either dead or low on voltage.

Try using Energiser Lithium Batteries. Ifound that they speed up the speed of the shuuter on the camera.
