Grab an adhesive strip's pull tab and slowly pull it at as low of an angle as possible out from under the battery.

Give the strip plenty of time to stretch and re-grip it as necessary. Avoid dragging it over the components or cables above the battery. Consider wrapping the strip around a tool for better leverage.

Repeat this for the other strip.

If a strip breaks off, try to retrieve it from under the battery. If you can't retrieve it, don't worry—move on to the next step for an alternate method.
