Description

The JCB CR2032 is a 3V lithium coin cell battery measuring 20mm in diameter and 3.2mm thick, designed to power car key fobs, watches, fitness trackers, calculators, medical devices and motherboard CMOS backup. The lithium chemistry provides stable voltage output across the battery's discharge cycle, maintaining consistent performance in low-drain devices.

CR2032 cells are the most widely used coin cell format in consumer electronics, fitting the majority of key fobs for cars manufactured from the mid-1990s onwards, digital watches, bicycle computers, glucose meters and home security remotes. The battery sits in a circular holder with the positive terminal facing up, marked by the '+' symbol visible on the battery face.

JCB CR2032 cells are built with leak-resistant seals to protect the device terminals and circuitry during storage and use. The lithium composition gives the battery a shelf life of several years when stored at room temperature, making it practical to keep spares on hand for emergency replacement. Each battery is individually blister-packed to maintain charge until needed.

Frequently Asked

What devices use CR2032 batteries?

CR2032 cells power car key fobs, digital watches, fitness trackers, bicycle computers, calculators, motherboard CMOS backup, glucose meters, bathroom scales, LED tea lights and many small remote controls. If your device specifies a CR2032, this battery is a direct replacement.

How long does a CR2032 last?

Battery life depends on the device's power draw. In a car key fob with typical use (10-20 button presses per day), a CR2032 typically lasts 2-4 years. In a watch or low-power device, it may last 5-10 years. Shelf life when unused is typically 7-10 years.

Can I use this in place of other coin cell sizes?

No. CR2032 refers to the specific 20mm diameter, 3.2mm thickness format. Other common sizes include CR2025 (2.5mm thick) and CR2016 (1.6mm thick). Using the wrong size risks poor contact or damage to the battery holder.

How do I know which side is positive?

The larger flat face of the battery marked with '+' and the model number (CR2032) is the positive terminal. The smaller face with the manufacturer's name around the edge is the negative terminal. In most devices, the positive side faces up when installed.
