Ozkar Posted June 1, 2009 Share #1 Posted June 1, 2009 Advertisement (gone after registration) I removed my M8 from my Billingham earlier today and it was really warm, almost hot to touch. The mode switch was set to OFF. The battery had completely discharged itself so I charged it and placed it back in the camera. It fired up well enough and seems to operate as it should. However, I'm traveling overseas shortly and don't want it to fail during my trip. Has this phenomenon been experienced by others? And is this some one-off event or an ominous sign of worse to come.

vla Posted June 1, 2009 Share #2 Posted June 1, 2009 i've seen exactly the same phenomenon on a loaned m8. it happened once during the weekend, otherwise that camera worked fine. i would definitely clarify this issue with leica prior to travelling. markus Link to post Share on other sites More sharing options...
jaapv Posted June 1, 2009 Share #3 Posted June 1, 2009 Somehow it must have switched itself on in the bag and off again on taking it out. It is perfectly normal for the camera to get hot when draining the battery completely in one go by half-pressing the release. I would check, if I were you, that there is nothing inside the bag that can "operate" the on-off switch and shutter release. Link to post Share on other sites More sharing options...

My first reaction was to check the power switch and it was definitely off. My Billingham is a pretty loose fit and I would have felt some catching or resistance. Who knows? But thanks for the suggestion. Ozkar Link to post Share on other sites More sharing options...

I would check, if I were you, that there is nothing inside the bag that can "operate" the on-off switch and shutter release. I would have to disagree with this. I have used one of my M8's, actually both of them at one time or another, to fully drain the batteries and have never had either of them get warm, let alone hot, to the touch while doing this. Of course they aren't in my bag at this time. Link to post Share on other sites More sharing options...
Doc Henry Posted June 1, 2009 Share #7 Posted June 1, 2009 Advertisement (gone after registration) Oskar, Is it the "death" of the battery? In your place,i will change it, for not to damage the camera It's not on the M8 but it's for computer : HowStuffWorks "What is causing lithium-ion laptop batteries to catch fire?"

Henry Thanks Henry, Please correct me if I'm wrong, but I think the issue you refer to relates to battery overheating during charging. I am not aware of this overheating occurring when a device is idle. Ozkar Link to post Share on other sites More sharing options...
charlesphoto99 Posted June 1, 2009 Share #9 Posted June 1, 2009 I had this happen to one of my M8's once, a long time ago. It didn't drain the battery all the way but was working on it. Felt really hot - disconcerting as I was showing up on a shoot, but it worked fine. I'll bet anything you forgot to switch it off when you put it in the bag and then it switched itself off pulling it out. It really is a wonky on/off switch design (same with M7).

Ozkar Oskar, If the battery starts suddenly to heat up, what is case here, battery therefore off-loaded with possible short-circuit (see the link) Therefore problem undoubtedly at the level of the battery according to me Is there another reason? I don't have this problem on my 2 cameras and my 4 batteries Light superheating when the battery is in charge is normal, but it is almost indiscernible (see the notice of the charger and battery) Regards Henry Link to post Share on other sites More sharing options...
michali Posted June 1, 2009 Share #12 Posted June 1, 2009 I had this happen to me last year on safari in Namibia. I put a freshly charged battery in the camera overnight and stored the camera in the bag. The next morning the camera was warm and the battery was very low. I put it down to 2 possibilities, 1. dirty contacts on the battery 2. The camera having been turned on by mistake. It happened once or twice on that trip, and hasn't happened since.

Andy- you're right it does have a sleep function, on the menu there's an "Auto Power Off" option which can be set to any one of 4 settings: " 2, 5, 10minutes or off. I've subsequently set mine to 5 minutes. I wonder however if dirty / soiled battery contacts could cause a short which could result in this warming up phenomenon?

Ozkar Posted June 1, 2009 Author Share #16 Posted June 1, 2009 Following a long night of rest and recuperation in the Billingham, my M8 seems perfectly fine this morning. The battery has maintained full charge and all seems well. I must say, I have from time to time placed my M8 in my bag while it was still turned on and it never became hot. In fact, auto power off is set to 5 minutes and the camera always went into sleep mode. Anyway, it seems fine now so I'm not going to fuss. Thanks for all the responses.

Shootist Posted June 2, 2009 Share #17 Posted June 2, 2009 It is not the battery heating up, altho that may happen at the same time, it is the camera that is heating up. This has happened to other users before and in some case was a prelude to SDS on some cameras. On other cameras it never happened again.
