I have a Kodak Z812 that I'm happy with except for one problem that's
cropped up, it seems to be using the batteries inordinately fast. I have both Sanyo 2700 mAH NiMH and the newer Eneloop 2000 mAH NiMH types that I have charged with a LaCross BC-900 on the Charge/Refresh mode to be sure the batteries were fully charged. If I put them in the camera and set it aside by the next day they will usually not even extend the lens, or if they do I get the low-battery indicator after a very few shots. If I use the camera right away it works fine, taking however many shots I need, whether the flash is needed or not. But if I put it away, the next day the batteries are dead or nearly so. I let my sister use two of the eneloops in her Kodak P&S and they worked for a week or so until she gave them back, so I don't think the batteries are bad. The camera has worked fine for a year or so, actually it still does other than this battery problem which started about a month or two ago. I wonder if the 2 Gig memory card that's installed could be the problem? Has anyone had a problem like this that could give me some ideas? -- dvus |

I remember seeing a report of exactly this sort of problem a while ago. See http://www.jlaforums.com/viewtopic.php?p=11693034 I saw another mention of a similar problem in a posting at Steve's Digicam Forums but I can't find the article at the moment. The problem seems to depend both on the camera brand/mode, and on the SD card brand/model. I don't know why, but hypothesize that some characteristic of certain cards can cause a camera's firmware to fail to power the card/socket down when the camera goes to sleep ("switched off"), and that the static current drain of powering the card eventually flattens the battery. Try a different brand or model/type of card. -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

I'm glad you pointed this problem out. I recently got a mail order memory
card for my new Canon A720IS and was worried that it wouldn't work properly. The camera manual stressed using only Canon SD memory cards. I only anticipated loosing picture files, but this is another issue to look out for that I never considered. The Dane-Elec 2 GB SD card I got seems to work OK. so far.

I remember seeing a report of exactly this sort of problem a while ago. See http://www.jlaforums.com/viewtopic.php?p=11693034 Very interesting. I brought up the SD card on a whim, but this info makes it worth investigating. For now I'll just pull the card and see what happens using only internal memory. I saw another mention of a similar problem in a posting at Steve's Digicam Forums but I can't find the article at the moment. If you look you'll see that I've been talking to a few people in there and the feeling of some is that the Z812's voltage requirements are more than some NiMH batteries can handle. I can't dispute that specifically, only anecdotally in that the camera worked well with NiMH for a year or so brfore this problem started, and I had the same 2 Gig SD card in it from day one. That doesn't preclude something from having changed within the card that could cause a leak, however, so I'm going to see what happens without the card installed. The problem seems to depend both on the camera brand/mode, and on the SD card brand/model. I don't know why, but hypothesize that some characteristic of certain cards can cause a camera's firmware to fail to power the card/socket down when the camera goes to sleep ("switched off"), and that the static current drain of powering the card eventually flattens the battery. Interesting theory. I guess it's certain that the internal cpu in the camera has an input sensing the presence of a memory card. What it does with that information is anyone's guess. Another friend told me about a guy who's camera would apparently turn off but remained on internally to some degree for some unknown reason, so your hypothesis seems feasible. Man, do you have to be an electrical engineer to take snap-shots these days? Try a different brand or model/type of card. Or none. That's as significant a change as I can think of. If it seems to make a difference, I'll go get a Kodak SD card. *That* brand had better work well! -- dvus |
