Filter capacitors in power supplies are almost always aluminum electrolytic types, because the capacity and voltage ratings make other types too expensive (if the necessary ratings are available at all). Heat accelerates the aging process, and it gets very warm inside a television set. -- Mark Roberts Photography and writing www.robertstech.com

I don't know what type of capacitor they use, but it doesn't have to hold much charge nor can it be stressed much to supply enough power to retain settings for 48 hours. I suspect it will last for many many years. Godfrey

But I always toss a set of fresh batteries in RIGHT AWAY when I remove dead ones for charging. I've never tested that 48 hours claim. I've left the DS batteryless for two days when I put the second body's NiMH batteries into the charger and simply forgot to put them back ... I took them along as backups for a photo session. The capacitor stayed up and I didn't lose any settings. So the 48 hour number is probably conservative. Godfrey

In the case of the *istD, it came already installed in the camera and died a few weeks later (so I then had to find the information in the owner's manual as to how to replace it, which was quite easy.)

The D comes with a CR-2016, the DS does not, according to their respective manuals. The DS uses a capacitor to power the settings storage, which lasts ~48 hours while the D uses the lithium battery. -Adam

Does that mean the S loses its setting if you don't use it for 48 hours? Or only if the main batteries are removed for 48 hours?

Re: CR-2016 Lithium Batteries for istDS
I don't think the DS uses such a battery. It's probably a cut and paste error. They just recycled the descriptive text of the *ist-D, for their DS review.
