Before removing any liners, check that your base battery adhesive matches the size and shape of the cutout in the frame.

Peel off the adhesive strip from its clear liner.

Align the adhesive strip with the top edge of the base battery recess and press it onto the frame.

Use the flat end of a spudger, or your fingers, to press down the five adhesive strips and adhere them to the frame.

Peel off the colored liner to expose the adhesive strips.

Align the new base battery with the top edge of the battery recess and press it to the frame.

Use your fingers to press along the battery to adhere it to the frame.
