Specialty batteries are becoming more common as your favorite devices are getting smaller and smaller. A button battery (coin cell) works the exact same way as AA and AAA ones. They have a round diameter, and two electrodes of complementary metals. A separator that technicians call electrolyte sits between them, and controls the flow of ions that make the electricity. Most button cells in use today are non-rechargeable and are found in medical implants, watches, hearing aids, car keys and memory backup.
