LP-E6's dropping like flies.
« on: May 27, 2013, 10:43:14 AM »
Having Biiiiiig problems with my 7D.

Picked it up the other day to use and it wasn't communication with the grip.

Tried it off battery only and seemed fine.

Picked up again yesterday, dead.

Only works with third party LP-E6.  Replaced internal CR1616.  Tried to charge one of my genuine LP-E6's and the charger just rapidly flashes constantly.  2nd LP-E6 goes straight to green light.

Tried the other one on camera and it worked for a while then bricked.  During that time the camera was giving me info on battery status (both around 95% charged, 2 status bars)

Never had lithium ion batteries fail on me before, and to fail at same time..

Any ideas?

There are electronics in the battery which shut it down when drained.  If you have a bad charger, it can zap the electronics in the battery and produce what you described.
 
Of course, it can be something else, like a counterfeit battery.  There have even been legitimate dealers reportedly selling them in Europe and England.
 
You might try buying a cheap third party battery to see if it also fails, that would point to a charger or a grip causing the issue.
 
Finally, it can just be Mr Murphy pulling his old tricks.

No idea, sorry, never came across such behavior. Just out of curiosity, a few questions:

1. Did you buy all your LP-E6 at the same time? I mean, are they all the same age?

2. Do you remember their "battery info" history? how many green/red bars and when? My ones, all bought at different times, went from 3 green bars to 2 green bars after about 1 1/2 years, then 1 red bar after 3 years. Now they're all 1 red bar, but still perform well. But I don't do video and don't use live view so much, live view and video stress them a lot more...

3. Did you ever run them empty? Or, do you often charge them when they are nearly empty (say, below 10%)?

Your post made me feel a bit anxious... LP-E6 were first introduced with the 5D2, it may be that in a few months we will begin to notice an hecatomb of them, who knows...

I don't have third party LP-E6 compatible batts because I prefer to use 6 AA Ni-MH Eneloop, a cheaper but valid alternative to compatible third party Li-ion batts, as an emergency power source since I already have lots of them for my Speedlites and I'm quite satisfied as far as performance is concerned.

2 genuine canon batteries (one came with camera)
1 thrid party, calumet, the only one which is still working.

Battery condition was 2 green squares, and charged to at least 90%

Bought the two failed batteries within a month, as said one came with camera.

I use them for video and so fairly often they run to the icon flashes then I change and charge.  Been fine up until now and it's curious that both fail at exactly the same time.

Only change I can think of is that I loaded on the x-video settings via the canon software last week.

Try with a different camera.
Same with or without the grip.
A different charger.
(like Mr. Spokane said: could be the charger).
Or the camera cant read the information on the chip (is it a problem in the cam or the charger?)
Summary: facts should lead you to the fact, that is common.

I had this painful moment once with the 5d2 and the grip. It was a little bit loose, this blocked the controls on the grip, but not on the body....

yep the grip is playing up as well.  Sometimes connects, sometimes dead, with the working calumet battery.

Strange. I guess you don't have fluke/multimeter/something to measure the actual voltage after charging?

Really bothersome the adverts in the posts made in threads. Well anyways, was going to ask where you purchased the LP-E6s because I recently bought a Canon 5D Mark III and was going to buy 2 spare batteries and of course will want to stray from where you bought them. Amazon? Adorama? B&H?

Let us know some news tomorrow... If something's broken let's hope it's the battery rather than the grip!

I don't see them, I use Firefox with Adblock Plus.  8)

I hope it's not the 7d body!

I think it's neither your 7D nor the grip. But if you want to sleep peacefully tonight, why don't you insert whichever kind of fresh AA-sized batteries in your grip and try right now? Disposable alkalines don't last long, actually only a few minutes shooting LV, but are fine for just running a test.

Thanks for the welcome. I have been on here once before when I wa looking up the Canon 7D MK II if it was gonna come out or not, which apparently didn't some time ago. well anyways thanks for clearing that up for me. Using Google Chrome at the moment and also glad doesn't affect the US heh. But, wouldn't be the first time a bad batch of batteries went out into the population. Think nikon even had a batch of EN-EL15s that would explode at one point.
