I had a weird problem this weekend while shooting a wedding. I had replaced my batteries with new EnergizerAA lithiums before the wedding,after about 50 shots, I get the "battery depleted" error on the LCD. I then changed those batteries(thinking maybe theyre defective) and about 100 shots into the new ones, same thing('battery depleted'). I then switched the camera off and back on, and the thing worked again for like 100 more shots, then the same error. Turn off/back on, it works again. Has anyone else seen this with the *istD?
ps. I dont recall getting the 'battery low' warning light on the display panel, I think it just died both times. I really doubt its the batteries since it works for a good while again after powering off/on.

Re:
I had the same problem with my cell phone last week. Left the wall wart at home (by accident) . Battery went dead and I plugged in the spare. That battery went dead and I plugged the first one back in. It came up happy and ran all day. Next day I switched again. I figure I got two hard days out of "dead" Lithium Ion batteries.

Re:
Battery charge indicators don't measure actual charge but voltage because there is no cost-efficient method to measure battey charge directly.
Instead, batteries are designed so that voltage goes down with charge. Now, the difficult thing is that not all batteries behave in the same manner. It is actually very hard to predict how a battery menufactured by xyz behaves.
I would guess that Pentax engineers did not have Energizer AA's in their mind when they defined the voltage alert level. I would suspect that the battery status indicator is calibrated for the CR-V3 batteries that were included with the camera body, or something else.
Only wild guesses above... And yes, I have encountered weird inidicator behavior with AA batteries, too. But not with CR-V3.
I bet your mobile phone battery indicator plays tricks, too.

They won't work with a Lithium battery. The controller circuitry doesn't understand this weird new battery. They don't work on electric kiddy bikes without changing the controller and then not all work as expected. They also don't work on full size motorcycles as a starting battery.
The Sure Shot Zoom S uses a 2CR5 6V lithium battery. You should be able to find one at an electronics or office-supply store. If all else fails, http://www.batteriesplus.com/product_search/31018-Rayovac-2CR5-Lithium-Battery-1-Pack-DASH--DASH-RAYRL2CR5--1.aspx
Try rechargeable batteries if your are using AAA or AA. Some cameras just stop working with the one-use batteries. If you have a lithium or other specialty battery, try getting another battery. Your battery may need to be replaced. I shoot a professional grade camera. I can shoot a whole wedding and part of the reception on one set of batteries. The brand I use is called Eneloop. You can't go wrong with these rechargeable batteries. The can be found at any place that sells camera supplies or off Ebay. They typically cost about $12 for 4 AA's. Best wishes.
Load 4AA with Energizer Lithium Batteries.
Set 580EX II's function to 12-0 and 05-0.
Make sure 5D's is not set to HSS.
No white dome parked on flash.
No bounce.
Set camera to "M" with max sync if you like, but 60 is fine.
Set F-Stop no greater than F5.6
Set ASA/ISO no lower than 200 but not over 1000.

I just experienced the same problem. Saturday I was playing with it, shut it off put it away. Sunday came it was completed dead with fully charged batteries and a new lithium battery it won't power up and I've got a wedding to shoot next week. What do I do?
Digital cameras require a large 'surge' of power when performing things like processing an image and saving it to the memory card.
Alkaline batteries work best when used in a device that draws power at a steady rate. They do not work as well when asked to provide a surge of power. Your batteries are indeed not dead, but they are sufficiently depleted that they can no longer provide that surge that the camera requires. Take them out and put them in something like a TV remote or a radio. They probably have quite a bit of life left.
NiHM and Lithium based batteries are much better at being able to provide the amount of current needed right up until they go dead.
The 100 shots you got out of your Alkalines is at the high end of what you can typically with Alkalines in your camera. The continuous shooting could be a symptom of the batteries getting low.
Another option to those previously listed are AA Lithium batteries which are cheaper than CR-V3's and last nearly as long. They are not rechargeable though.
