About this product
The CR2032 is a non-rechargeable 3 V lithium coin cell measuring roughly 20 mm across and 3.2 mm thick, with a flat discharge curve and long shelf life. It powers real-time clocks, memory backup, key fobs, calculators, and other low-drain devices from a standard 20 mm holder. The cell must not be recharged, short-circuited, or swallowed.
