Canon PowerShot A80 Internal Battery Replacement

Introdução

Although designed for long-lasting life, rechargeable batteries will lose their ability to hold an electrical charge and must be replaced.

Open the door to the CompactFlash memory card slot by sliding it towards you and swinging it open.
Remove the memory card if it is still in the camera.
Use the Phillips #00 screwdriver to remove the single screw underneath the memory card slot door.

Remove the Phillips #00 screw located inside the top of the memory card compartment.

Open the battery compartment door at the bottom of the camera by sliding the latch to the right and then sliding the door down.
Remove the batteries from the compartment.
Remove the three Phillips #00 screws located inside the battery compartment.
The screw on the left is longer than the other two.

Remove the top lid of the camera.
Be cautious of the fragile mylar cable that connects the lid to the main body of the camera.
Removing the lid takes a little force. Do this gently. There may be a snapping sound.
The door to the memory card compartment will be freed and should be removable now.
In other versions of this camera, there is a tab that secures the top from the wrist strap. If yours has this, you won't be able to completely separate the top until you have removed the top screw in Step 8.

The upper screw from Step 6 must be removed first, ( also fixing top lid )

Open and pivot the LCD screen to its widest open position.
Remove the rear cover by pulling it straight away from the body of the camera.
When reassembling the camera, remember to replace the screws in the same location from which you removed them. Otherwise, you may damage the camera.

Unscrew the top 3.9mm, middle 2.7 mm, and bottom 2.9mm screws that hold the metal foundation covering the internal battery.
