Coin Cell Battery

Button cells, also known as coin batteries, are small, single-cell batteries shaped like a coin or garment button—typically ranging from 5 to 25 mm in diameter and 1 to 6 mm in height. Their compact size and slim profile make them ideal for powering low-profile, compact electronic devices.

These batteries are widely used in applications such as:

Watches

Hearing aids

Cardiac pacemakers and defibrillators

Calculators

Computer backup systems

Industrial instruments

Test equipment

Feature phones, copiers, and fax machines

Personal computers and workstations

Due to their reliability, small footprint, and long shelf life, coin and button cells remain essential in both consumer electronics and specialized medical or industrial applications.
