Internal battery

A friend of mine has just had to change the internal battery in his Nikon because the time and date went dead. I was wondering if our Pentax cameras have one to keep the time and date memory in tact.

I had cause to dig the K5 out today to attempt an SDM-screw drive conversion and remembered this thread.

It's got to have been in excess of 2 years since the body saw daylight and had been stored battery-less in that time at room temperature. Upon powering up, the date had reset to 01/01/2010. I used a DC power supply whilst working through the conversion and disconnected it when done. A few hours afterwards, the calendar and clock are still showing today's date.

I've only lost the date settings on my long neglected *ist DS - the K5iis still hold the settings even with little use.

That DC power supply is a great little accessory to have, I've used it for sensor cleans and for a very heavy macro set-up a few years ago!

It certainly is.

It's also something that hasn't changed - from the K5 to my K1 ii and KP - same DC fitting. Probably fits other models....
