Re: Cannot communicate with battery - 7D

My faith is also being tested with Canon as well with all of this, lack of responses.

I posted back on Dec. 19 after I shelled out $300 bucks for the "Comminuicate' fix that my EP-L6 battery showed 1 red bar, After buying new Canon lithium batteries (another $200) - showing 3 green bars. Well as of March 15th they BOTH now show 1 red bar - meaning "pretty close to dead."

 

1001 photos since Jan...not even close to my normal photo taking and the batteries are almost shot?? - 1000 pics, heck I really haven't been out that much this winter, its been downright miserable.

 

No idea whats going, I'm a tad disgusted at this point.

 "I can also not imagine that they have "shills" like ebiggs1 ..."

From Merriam-Webster.

To talk about or describe someone or something in a favorable way because you are being paid to do it.

 

Hmmm, I am not being "paid" by Canon or anybody for that matter.  I am retired from Hallmark Cards, Inc.

And , yes, you must have a active imagination.

Even shills offer the truth from time to time.  Now you may continue to complain about your problem or you can do something about it.

This is a public forum and not the Canon Service center.  It is not the place to request Canon help or service.  It is a public forum for the public to discuss Canon products.

 

"....we should be getting better answers from a vendor like that..."

 

And you should contact the vendor in the correct way through the right means.  Not on the public forum. Smiley Surprised

Re: Cannot communicate with battery - 7D

I also have this problem.  I have multiple Canon and non-Canon batteries which all work in my 5Diii and get the "cannot communicate" problen on my 7D.

 

Although I was skeptical, I tried bud411's solution.  IT WORKED FOR ME!

Re: Cannot communicate with battery - 7D

Glad to hear this worked for someone else. Maybe it wasn't just a fluke (or the drop onto the tile floor). Would be interesting to hear others try this to see if it works.

 

After my camera started operating properly, I updated the firm ware to the latest version & all still working like it was designed to do.

Re: Cannot communicate with battery - 7D

I am experiencing the same problem.  "Cannot communicate with battery."  I have 10 canon batteries and I use them one at a time so I don't think it is the batteries.  But for me the problem is a little more serious because I shoot video.  When the battery expires there is no warning from the camera (it just shuts off)  and if it expires while recording video you will be unable to recover the current clip.  This could be devastating if you're shooting an interview on the run, say at a red carpet event and the battery expires during the only sound bite with the elusive star you're hoping to get a quote from.  There really are some reasons to shoot on tape.  I wish canon would speak up about a fix instead of just collecting out money.

Re: Cannot communicate with battery - 7D

I’d sure like to know what Canon is going to do to stand behind it’s product. After so many people complaining of the same issue, and having spent so much money on OEM batteries, I think it is high time Canon faces the music. Announce a recall or face the real possibility of a Class Action.

A VERY real possibility.

"A VERY real possibility."

 

Just out of curiosity, by whom?

Re: Cannot communicate with battery - 7D

I've met 14 different photographers here in Chicago alone who've experiences the same issues.  2 of them have family members who are attorneys and another IS an attorney.

They are gathering names as I write this from the different sites around the internet....

Re: Cannot communicate with battery - 7D

Count me in, with the amount of money I had to pay for the repair, the batteries. I had to put off purchasing other needed equpiment. Again, said it once, twice..I'll say it again. I don't understand why Canon will not acknowledge this obvious common problem.
