A CR2032 battery is a button cell lithium battery rated at 3.0 volts. It is commonly used in computers as a CMOS battery, calculators, scientific instruments, watches, and other small devices. 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 temperatures as high as 85°C or as low as 30°C, [1]while the CR2032 is specified over the range -20°C to 60°C. [2][3] BR2032 also has a much lower self-discharge rate. Using a BR2032 in place of a CR2032 will not damage equipment, and in most cases will function properly
