Recently when inserting a new battery into my 7D I started getting an error message like "camera does not recognise battery do you want to use it anyway?" When I hit the OK button the camera would work but the LCD display gave no feedback on battery life. Just now the camera has stopped working altogether. Any ideas?
I take it this is a non-Canon battery? If it does this with a Canon battery, then the board that senses the charge level is bad.
However, the 7D has a history of loose screws which will short out various circuit boards of the camera. [screws that hold the DC to DC power board]

Defective mechanism, a stucked mechanism is present. camcorder are smart it can detects error and shuts down itself for safety. earlier models dominoes the defect if the user is not quick enough to react when something goes wrong with the camera. You need professional service to fix it.

Most DSLR cameras (like your Canon) don't have a live view - in other words, you can't "see" the image before you capture it. You must use the viewfinder.

If your camera is still under warranty, the best thing you can do is to take it to the nearest official Canon repair shop and Canon should fix it for free.
If your camera is out of warranty , or if Canon refuses to repair it for free (happens sometimes if for example they suspect the camera has not been treated properly) you can try some of the methods listed here to repair it yourself. These simple methods have helped a lot of people fix their cameras.
Before trying any of the suggestions, make sure your Canon has fresh batteries and it is in recording mode.
1) Remove the batteries from the camera, wait for a couple of minutes, then put them back in and turn the camera on.
2) Try compressed air. With a fine tip blow off gun and dry compressed air (20 lbs) set the tip between the lens turret and the camera body and turn on the air while moving the tip around the lens. It should remove all dust and sand. Turn the camera on and it should function fine.
3) Another method is to tap the padded USB cover part on a hard surface, for example, a desk. It sounds so simple, but very often in works.
4) Try forcing the camera lens:
Turn off the camera. Place it on the back with the lens facing up and take a look at the spacing between the lens and the lens housing. If you notice that the gap is not even all the way around the lens, the problem should be easy to fix. This type of a problem usually occurs if the camera was dropped while the lens was extended.
Simply - VERY GENTLY - press down the lens on the side where the gap is the biggest. You should hear a "click" as it pops back into place. Try powering the camera back on.
If the lens doesn't extend at all or it extends, and then retracts again, do the following. Turn the camera off. Take the camera in one hand and with the other gently take one part of the lens and gently move it round in a circular movement. Do so with both sections of the lens. You will hear a "click" as it pops back in place. Power the camera on.
Another version of this fix would be to pull and twist on the largest ring of the lens while turning the camera on. Listen for a "click". If at first the focus seems to be off, turn the camera on and off and take lots of pictures, close ups and distance. Focus should slowly start improving.
5) If that doesn't work, there is an online guide for dismantling Canon cameras and fixing the E18 error. (NOTE: Try this only if your camera is no longer under warranty!) It is a great guide with pictures and it can be found here.
There are 2 other guides, one Bulgarian and one Estonian with the take apart procedure for Canon cameras. They are not in english but have a lot of pictures which help with the process.
- Bulgarian guide
- Estonian guide

Do you have a way to test the battery and you know it's ok?
Those batteries have built-in protection circuitry that can cut out or turn off the battery entirely if it detected a problem like a short circuit, etc. And it may not get over it.
Try a 2nd battery or the AC power adapter directly.
Also check that the 3 little pins in the camera DC input jack are intact, straight, and not touching each other.
Some camera's won't turn on if the memory card door is open or the card is ejected but I tested that on my G3 and it still turns on either way.
Ah.... and lastly... there is a little electrical limit switch connected to the battery cover door that disables the camera if the battery door is open. It gets pressed by a small plastic piece attached to the battery cover when you close the battery door. If the plastic piece or the tiny, recessed switch has an issue then the camera won't turn on The switch could be bypassed internally (not easy to do) if that was the problem.
Look for a tiny, thin, black plastic switch about as thin as a staple down in a recessed hole (slot) near the battery cover hinge. Try gentle pushing the battery closed switch "over" a little. You can tell which way to push by observing how the battery door slides into position as you close it. I was able to turn on my camera with the door open by doing this.
The switch is very tiny, don't break it.
If the battery door isn't closing all the way that would also cause the same issue.
