Description

The Panasonic CR2032 is a 3V lithium coin cell battery measuring 20mm diameter by 3.2mm thickness, designed to power compact electronic devices requiring stable voltage over extended periods. The lithium chemistry provides higher energy density than alkaline alternatives, delivering consistent 3V output until end-of-life rather than gradual voltage decline.

Designed for car key fobs, digital watches, calculators, medical devices (glucose meters, digital thermometers), motherboard CMOS backup, LED candles, and small remote controls, the CR2032 operates across a temperature range of -20°C to +65°C. The battery carries a 10-year shelf life when stored at room temperature, making it suitable for emergency backup applications and devices with infrequent use. The single-pack blister format includes child-resistant packaging.

The CR2032 designation refers to the cell's physical dimensions: CR indicates lithium manganese dioxide chemistry, 20 is the diameter in millimetres, and 32 is the height in tenths of a millimetre (3.2mm). This standardised sizing means the Panasonic CR2032 is interchangeable with other manufacturers' CR2032 cells and compatible with devices specifying BR2032, DL2032, ECR2032, or SB-T15 equivalents. Typical capacity sits around 220-240mAh depending on discharge rate.

Frequently Asked

What devices use CR2032 batteries?

Car key fobs, digital watches, calculators, motherboard CMOS backup, glucose meters, digital thermometers, bathroom scales, LED tea lights, bike computers, and small remote controls commonly use CR2032 cells. Any device specifying CR2032, BR2032, DL2032 or ECR2032 accepts this battery.

How long does a CR2032 last?

Service life depends on the device's current draw. In a car key fob with occasional use, a CR2032 typically lasts 3-5 years. In a watch drawing microamps continuously, expect 2-3 years. The battery carries a 10-year shelf life when unused and stored at room temperature.

Can I use rechargeable CR2032 batteries?

Standard CR2032 cells are single-use lithium primary batteries and cannot be recharged. Attempting to recharge them risks leakage, overheating or rupture. Rechargeable LIR2032 cells exist but deliver 3.6V instead of 3V, making them incompatible with devices designed for standard CR2032 voltage.

What temperature range does it operate in?

The Panasonic CR2032 operates from -20°C to +65°C. Performance degrades slightly at temperature extremes, with reduced capacity in very cold conditions and accelerated self-discharge in heat, but the cell remains functional across this range.
