The manual tells you to use the viewfinder cover from the accessory shoe to open the battery door. Your camera most likely does not have this small, easy to lose, piece of plastic. You can use a pen cap or other small piece of plastic to press the tab that holds the battery door closed.

If your camera has the action grip, it will need to be removed in order for the battery door to be opened.

Canon AE-1 Check the Camera Battery

To check the battery follow these steps:

  1. Turn the main switch to “A.”
  2. Press the battery check button. Shooting is possible if you hear about six or mre “beeps” per second. If the camera beeps slowly (about three or fewer “beeps” per second), there is not enough power. In this case, replace the battery.

  1. With normal use, the battery should last about one year.
  2. It is necessary to take special precautions with the battery when you are shooting in temperatures below 0°C (32°F). See p. 68.
  3. Remove the battery if you do not expect to use the camera for about three weeks or longer.
