Use tweezers or your fingers to grab the pull tab and pull it down so it's flat against the frame.

Slowly pull the adhesive out from under the battery at as low of an angle as possible.

Give the strip plenty of time to stretch and re-grip it as necessary. When the strip becomes too long, wrap it around your tweezers and continue pulling.

If the strip breaks off, try to retrieve it from under the battery. If you can't retrieve it, move onto the next strip.
