In the short time I have researched these batteries this morning, I've come to the same conclusion, that it's not worth switching from my Eneloops.Hope you find at least some of this informative and/or helpful, Peter
"If it ain't broke, don't fix it" rings true here.
These recharegable alkalines aren't apparantly meant for high current drain and/or frequent use applications anyway.
I've used my Annsman Energy 8 charger for many years with no issues so far.

Quote:
Though rechargeable alkaline batteries are relatively cheap and contain a high charge-capacity, their rechargeable capacity will vary by how much they are discharged:
If they are discharged by less than 25%, they can be recharged for hundreds of cycles to about 1.42V.
If they are discharged by less than 50%, they can be almost-fully recharged for a few dozen cycles, to about 1.32V.
After a "Deep Discharge", they can be brought to their original high-capacity charge only after a few charge-discharge cycles.
Not much use for DSLRs & flashes then.Though rechargeable alkaline batteries are relatively cheap and contain a high charge-capacity, their rechargeable capacity will vary by how much they are discharged:

I saw some rechargeable alkaline batteries in a supermarket yesterday and wondered if anyone here has used them.
They seemed expensive to me, but I expect they are cheaper online.
4 X AA's + 2 x AAA's and mains charger were just over €30.00
Their main advantage would be that they deliver 1.5v instead of the 1.2v of NiMh's. They are also supplied ready for use and will apparantly hold their charge for up to 7 years.
These are the ones I came across.
EDIT: It seems they are not meant for use in high drain situations, like cameras. They are more suited to low use/low drain items like remotes & torches etc.

Try sensor cleaning mode to see if the shutter opens fully.

"JP" would not have told you that you can reload your camera with previous firmware, if you first edit the firmware to make the camera think that you are reloading the same version that it has installed already.Stefan commented that the upgrades can be taken back to a previous version - that's not the advise I was given by "JP" for my K10D unless the requisite Pentax kit is to hand.
Apparantly, by using a HEX editor, you can edit an older firmware file and change the version number to match the version number that is already installed on the camera.
Go through the normal update procedure and it should load. You'll then be back to the previous version.
Disclaimer: If you try this, you assume all risks. Don't blame me if it goes wrong.

The downloaded file contains the readme text file.
The update process has remained unchanged from the very first *istD.
Download the file and run it (.exe). This will extract two files, the readme.txt being one, the firmware, the other.
Charge your battery.
Format an SD card in the camera.
Remove card from camera and attach it to your PC with a card reader, or leave it in camera and connect camera to PC using the supplied USB cable.
Copy the extracted firmware file to the root directory of the SD card.
Put SD card back in camera, with power off.
Press and hold the menu button on the camera, power on the camera.
You will now see further instructions on the rear screen.
Choose yes to update, wait for the completion message and flashing SD access light.
Turn off camera.
Turn on camera and reformat the SD card.
Job done.
To check the firmware version, press and hold the menu button and power on the camera.
Pentax instructions can be found here, and the latest version is 1.11, not 1.02 as you noted earlier.

I stay with Pentax because I have a huge investment in lenses and to change, would mean divorce.
If I needed capabilities that Pentax could not offer, and I could justify it to my war department, I would buy whatever brand offered it. I'd still keep my Pentax gear though.
