Product Description

A CR2032 battery is a button cell lithium battery rated at 3.0 volts. It is commonly used as a CMOS battery in computers, calculators, remote controls, scientific instruments, kitchen, office and personal scales, wireless doorbells, garage door remotes, watches and other small devices. Nominal diameter is 20 mm, nominal height is 3.2 mm. CR2032 indicates a round cell 19.7–20 mm diameter and 2.9-3.2 mm height as defined by the IEC standard 60086.[1] Review of 14 data sheets from different suppliers show a range of weights from 2.8 g to 3.9 g. Except for the two extreme outliers, all reported weights were between 3.0 g and 3.2 g, with the mode being 3.2 g. The BR2032 battery has the same dimensions, a slightly lower nominal voltage and capacity, and an extended temperature range compared with the CR2032. It is rated for a temperature range of -30 °C to 85 °C,[2] while the CR2032 is specified over the range -20 °C to 70 °C.[3] BR2032 also has a much lower self-discharge rate.[quantify] Using a BR2032 in place of a CR2032 will not damage equipment, and in most cases will function properly.
