Description
The Energizer CR2032 is a 3V lithium coin cell battery supplied in a 4-pack blister. Each cell measures 20mm diameter by 3.2mm thick and delivers consistent voltage to watches, calculators, car key fobs, fitness trackers, remote controls, small LED lights, and medical devices such as glucose monitors. Lithium chemistry provides stable output across the discharge curve and a shelf life of up to 10 years in storage.
CR2032 cells are among the most commonly specified coin batteries in consumer electronics, automotive keyless entry systems, and building access control fobs. The Energizer CR2032 operates across a temperature range of -30°C to +60°C, making it suitable for devices used indoors, in vehicles, and in outdoor equipment that experiences seasonal temperature variation. The batteries fit standard CR2032 holders and are interchangeable with cells labelled DL2032, ECR2032, and BR2032.
Energizer's design includes leak resistance features that reduce the risk of corrosion inside the battery compartment if a cell is left in place beyond its useful life. The silver-tone metal casing provides both the positive terminal (top face) and negative terminal (bottom face), with an insulating gasket around the rim. Each cell weighs approximately 3 grams and the 4-pack blister format allows spare batteries to be kept sealed until needed.

Frequently Asked
What devices use CR2032 batteries?
CR2032 cells power watches, calculators, car key fobs, fitness trackers, remote controls, small LED lights, bathroom scales, bike computers, glucose monitors, and CMOS memory backup in computers. They're one of the most widely used coin cell sizes.
How long do CR2032 batteries last in storage?
Energizer CR2032 lithium cells have a shelf life of up to 10 years when stored at room temperature in their original blister packaging. This makes them suitable for keeping as spares.
Are CR2032, DL2032, and BR2032 the same?
Yes. CR2032, DL2032, ECR2032, and BR2032 all refer to the same 20mm diameter, 3.2mm thick, 3V lithium coin cell. The different codes are manufacturer-specific labels, but the cells are physically and electrically interchangeable.
Can CR2032 batteries be recharged?
No. CR2032 cells are non-rechargeable lithium primary batteries. Attempting to recharge them can cause leakage, venting, or rupture. Only cells specifically labelled as rechargeable lithium (such as LIR2032) can be safely recharged.
