Use a pair of tweezers to peel up the black pull tab on one of the stretch-release adhesive strips until you can grip it with your fingers.

Pull the strip out from under the battery at a shallow angle. Go very slow and use steady force, giving the strip plenty of time to stretch and unstick itself from under the battery tray.

Pull the adhesive strip until it’s completely freed from underneath the battery tray.

Repeat for the seven remaining adhesive strips.
