Time and Date settings

Hi
I have a fairly recent but irritating problem with my K-r in that when I remove the battery to charge, it loses the time and date settings. This can be as quick as an hour or less.
I cannot find any reference in the manual to a back up battery, so is this a fault, or is there a battery I can change which hold up the settings?

Cheers!

Yes there's a backup battery in the camera, but it's not designed to be replaced at home, unless you're comfortable working with cameras of course.

Hi, thanks for the reply!
I guess I wouldn't be happy if it involves any degree of dismantling, so I will take it to a local dealer!

Cheers

I'm not sure how long the internal battery should hold the settings (seems like a couple of hours wouldn't be unreasonable, but...), but you can always get another battery, and swap them out while one's on the charger. I like to keep both of mine fully charged, if possible. The alternate road is to get the AA-adapter and keep a set of lithiums on hand, or the rechargeable AAs (most folks on the forum recommend Sanyo Eneloop rechargeables).

That's a plan - I use the AA adaptor usually, but I could swap for the Usual battery while the camera is on charge

disappointed

I'm disappointed that this little battery that holds the date and time while the main battery is out is going to be an expensive service at a camera shop. It should be user replaceable. The manual makes no mention of any of this.

I've had the same thing happen to my KR if I stored the camera for a few days without a main battery so if you allowed you main battery pack to discharge fully the internal storage cell may also have discharged
It is always a good practice to bring your camera body into a local camera repair shop for a professional cleaning every couple of years for a cleaning and a general checkup. The service technician can check the internal storage cell and it's connections at the same time and change it if necessary and the cleaning will definitely extend the life of your camera. It may be difficult to find a camera repair shop in your local area but your local camera shop should be able to help you find one.

My K-r has recently begun exhibiting this problem. Very disappointing for a two year old body with less than 2000 shutter actuations!

Already an old thread but I've solved the time/date problem with my two K-rs. There is a backup battery inside. First I got the manual for the camera and then, using it, opened it until I got to the main board. On it there's a small coin cell which is not listed as a replaceable part. I got a replacement from Farnell, popped it in and closed the camera again only to find it didn't work at all anymore. This turned out to be due to a flex print connector that had popped out during re-assembly. I intend to create a little write-up about the process on my website (Polonaise PIC projects).

Just follow the manual to the letter and you'll be fine. Pro tip: as there are many types of screws keep the ones for each step in a seperate ZIP bag. You will have four bags until you finally get to the wretched battery.

Good luck!

My old Nikon D40 is getting to be this way. l just store it with a battery that's at or near full charge. l have 2 batteries for it, so l can charge one while the other is in the camera then switch them out quickly.

best to take photos of each side of the Kx (Kr etc), print them, 2mm holes were the screws are located so you insert each screw right there and afterwards know which one goes where! (See my tutorials for K30 etc.)

The backup battery is often this one:
DCK-3R3E204T614-E Elna America | Kondensatoren | DigiKey

Different to the Seiko MS 412 or Seiko 621 which are Lithium batteries

while the ELNA is a supercap.

Don't know which one would last longer. Should be the ELNA.
Lithium batteries, if stored for long time and discharged too low are finished then.
Should be written in manuals for owners!


Best solution was the venerable *ist DS were one could change it!
