Pry up with the plastic card to separate the battery from the frame.

Remove the battery.

If there's any alcohol remaining, use a lint-free cloth to wipe it off or allow it to dry before installing a new battery.

During reassembly, remove the old adhesive and apply stretch release adhesive strips, double sided adhesive tape, or pre-cut adhesive to secure the new battery.

Do not reuse the battery after it has been removed, as doing so is a potential safety hazard.
