Apple AirPort Extreme – Disassembling procedure – How to replace the backup Battery

Disassembling procedure - Outer Case

First start by peeling off the outer rubbery covering on the bottom of the device.
CAUTION: This part is very fragile, so it is recommended that a blow dryer is used on the covering to heat it up. Simply blow dry the covering while slowly peeling it away, and the covering will not tear.

After removing the rubber covering, unscrew the five 4.9mm Phillips screws in the holes of the plastic casing.

After unscrewing all five screws, remove the plastic casing. The back should now look like the picture shown.

The inner metal casing is latched inside the outer white plastic shell, so insert a pry tool underneath the metal casing and pry it apart from the shell. It should make a click when it comes apart.

Remove the outer casing. The exposed logic board should look like this.

Remove the metal casing by gently prying the logic board away with you hands.

This should be pretty easy; you already removed the screws holding these pieces together.

Remove the battery by gently "shoving" it out with the plastic tool.
