Yes, I thought of that but on the other hand, LCDs are not supposed to burn. Firing the shutter 700 to 1000 times is risky too.

Pascal, that's an interesting data point, one I wouldn't be willing to do on my own camera. Did you set it on C and hold the button down for 5+ minutes or shoot more slowly? Did a blank or boring frame get written to the card on each shot? Did you have to stop when the card got full, or was there a way to fire steadily without having the shots recorded? How long did it take in all?So I did a deep discharge by firing the camera over and over, more than 700 shots and now, it works fine.
Ok, I shot with a card, C mode, shutter 1/8000th, cap on the lens & jpeg.Pascal, that's an interesting data point, one I wouldn't be willing to do on my own camera.

That is interesting. I tried leaving the camera on and the LCD off on 4 different batteries. One was dead in maybe 3 hours, 2 others closer to 6 hrs and the last one longer than that. I have about 12K images on the M8 s and recharge everytime I use the camera. Always start with charged battery and formatted card. But I think Guy is right ...I probably need a few new batteries. RogerInteresting Scott now we can't truly go by mine because they are suspect to begin with and your comments just may have enforced my thinking on my overall i think my batteries maybe at the end of there useful life. The reason I say that is because maybe only 3 or 4 hours to deplete mine. I just did the camera on the whole time and no LCD. Hmmm
I have a little shoot today but will not get past 80 frames in this case though. i need to go out and burn some frames to see if this helped any.
Well, this is one of the best descriptions, to kill Li-Ion batteries indentionally.Well after what went on in Moab with my batteries failing in the cold weather. i was inspired to deep recycle my batteries all six of them and almost done. But if you want to do this , here is the process turn camera on and drain to fully discharged than charge over again. Make sure in the menu you set camera to not turn off.
From the view of the Li-Ion battery, a "full recharge cycle" is a recharge from below 50% capacity. Common batteries will accept 300-500 such recharges and than will die in short time.Now my batteries maybe close to end of useful life since there are countless recharging and over 30 k on my actuations with my bodies. not sure how long these batteries will truly last but if anyone will know it will most likely be me first since i had these since day one and maybe have shot more on them than most people. Hopefully this deep recycle will bring them back to life much better.
Of course, from the point of view of an user, you are quite right. I am sorry, that my first post (or reply, reading here from day one) is a kind of bad news.Well interesting there still alive and well but have to be honest i have seen a bunch of reports on this and they contradict each other. Not sure what to make of that. Not being a engineer here so whatever works is fine with me but it needs to be clear. I have only done this twice but even leica recommends this to reset the camera. many other folks have also gone this route and seem okay. Now these were taken all the way down to exhaustion and took a full charge as I know it , maybe not. I need to get out there and shoot to see how long the life is, maybe it got shorter. But after the cold issue something needs to be addressed with mine.
I've always been reluctant to use the car charger because I've heard the batteries can be damaged if they are removed from the charger before charging is completed. Since I'm normally not in the car long enough for a full charge, I avoid doing it.Tim,
Not that this may be of any help now, and not being sure of your method of travel on your recent California coast trip, but did you have the car charger attachment along to charge things while driving from place to place? I know it sounds a bit much, but after having batteries quit when I thought they were fine, it has saved me a few times to at least get some juice into it between stops, unless it was totally dead. (I keep all my car charger components for various devices in a small kit that I usually leave in the vehicle. I find that all those things do little good when left at home.)
Hope that the deep discharge/recharge cycle "fixes" it, but as Guy mentioned, it may be worth returning it to dealer/Leica for replacement. It could really be a bad battery.

I would think so as well. I have two old (5000 exposures) batteries and two new ones coming soon, so I'll do a little testing on this.We have to remember that the suggestion was to discharge the battery using the M8. I assume the M8 will shut down before the battery voltage gets so low as to damage the battery.
That's what people do today. But this experience was about 10 years ago. There's one other interesting aspect with laptops -- most of them can be operated with only the AC converter plugged in and the battery removed. From time to time I have had what seems like a totally dead battery in a laptop, and find that removing the battery lets me get booted up, then replacing the battery leaves everything working just fine. Another reason why the M8 should have an aux power input, to prevent some of the causes of apparent SDS.In regards to the Thinkpad batteries and monitor program, it will suggest a recondition which involves unplugging the laptop and turning off the shut off timers to drain the battery, much like Guy described in his first post of this thread.
I'm just suggesting that before you give up on them, try one deep discharge and recharge and see if they come back.I guess the question is this , are mine just worn out from time and use. I know this can happen and sounds like the case.
