Duracell CR2032 Lithium Coin Cell Batteries - 3V (2 Pack)

The Duracell CR2032 is a 3V lithium coin cell battery supplied in a 2-pack, designed for compact electronic devices that require long-lasting, stable power. Each cell measures 20mm diameter by 3.2mm height and uses high-purity lithium chemistry to deliver consistent voltage output across the discharge curve. The batteries carry Duracell's Duralock Power Preserve technology, which guarantees up to 10 years of shelf life when stored at room temperature.

Commonly used in car key fobs, digital watches, fitness trackers, glucose meters, remote controls, bathroom scales and motherboard CMOS memory backup, the CR2032 is one of the most widely specified coin cell formats in consumer and medical electronics. The 3V output suits devices that require higher voltage than silver oxide button cells (typically 1.5V) but in the same compact form factor. The lithium chemistry provides stable voltage until near the end of discharge, avoiding the gradual power drop that can cause intermittent device operation.

The blister pack contains two cells with child-resistant packaging that requires simultaneous pressure and twisting to open. Each cell weighs 3g and the pack dimensions are 84mm wide by 119mm tall by 5mm deep, making it suitable for drawer storage or travel kits. Duracell sources the lithium from high-purity feedstock and manufactures to IEC standards, with internal safety features that prevent short circuits if the cell is accidentally pierced or crushed.

What devices use CR2032 batteries?

CR2032 cells power car key fobs, digital watches, fitness trackers, glucose meters, remote controls, bathroom scales, LED tealights, and computer motherboard CMOS memory backup. Any device marked CR2032, DL2032 or ECR2032 on the battery compartment uses this format.

How long does a CR2032 last?

In storage, up to 10 years with Duralock technology. In use, lifespan depends on the device's current draw. A car key fob typically runs 2-3 years on a single CR2032, while a low-draw digital watch may last 3-5 years. High-drain devices like active fitness trackers may need replacement every 6-12 months.

Are CR2032 and DL2032 the same?

Yes. CR2032 is the IEC designation, DL2032 is Duracell's internal product code for the same specification. Both refer to a 20mm diameter, 3.2mm height, 3V lithium coin cell and are fully interchangeable.

Is the packaging child-resistant?

Yes. The blister pack requires simultaneous pressure and twisting to open, meeting child-resistant packaging standards. Store out of reach of children — coin cell batteries pose a serious ingestion hazard.
