A wooden surface is not the best choice for this test. Wood absorbs more energy and items don''t bounce as well. 2. Replace the battery if it bounces when you drop it. Look at how the battery behaves when it hits the surface. A fresh battery will plop down without bouncing. It may roll over onto its side, but won''t bounce back up. An older battery will bounce
