Description

The Energizer CR2032 is a 3V lithium coin cell battery measuring 20mm diameter by 3.2mm thick, designed to power small electronic devices requiring stable voltage over extended periods. The lithium chemistry delivers consistent 3V output from full charge through to depletion, preventing the voltage sag that can cause device malfunctions in critical applications like car key fobs and medical monitors.

Used in automotive key fobs and remote starters, fitness trackers and smartwatches, digital thermometers and glucometers, wireless computer mice and keyboards, motherboard CMOS backup, LED keychain torches and small calculators. The CR2032 form factor is one of the most widely adopted coin cell sizes globally, with cross-compatibility across devices coded DL2032, ECR2032, BR2032, KCR2032 and other manufacturer-specific part numbers referring to the same 2032 cell dimension.

The battery operates across a temperature range of -20°C to +70°C, maintaining function in car interiors during summer heat and outdoor winter conditions. Each cell weighs 3g and comes in child-resistant blister packaging meeting safety standards for lithium button cells. Shelf life extends to 10 years when stored at room temperature, allowing stock to be kept on hand for emergency replacements without degradation.

Frequently Asked

What devices use CR2032 batteries?

CR2032 cells are used in car key fobs and remote starters, fitness trackers and smartwatches, digital medical devices like thermometers and glucometers, wireless mice and keyboards, computer motherboard CMOS memory backup, digital scales, LED keychain torches and small calculators. Any device marked CR2032, DL2032, ECR2032 or BR2032 takes this cell size.

How long does a CR2032 last?

Service life depends on the device's current draw. In a typical car key fob used several times daily, a CR2032 lasts 3-5 years. In low-drain devices like a computer motherboard CMOS, it can last 5-10 years. High-drain devices like active fitness trackers may require replacement every 6-12 months.

Can I use a different brand or code number?

Yes. CR2032, DL2032, ECR2032, BR2032, KCR2032 and similar codes all refer to the same 20mm diameter, 3.2mm thick, 3V lithium coin cell. The letters before 2032 indicate the manufacturer or chemistry variant, but all are functionally interchangeable in devices requiring a 2032 cell.

Is the packaging child-resistant?

Yes. This single-cell blister pack uses child-resistant packaging meeting safety regulations for lithium button cells. The cell is sealed behind a plastic bubble that requires scissors or significant force to open, reducing the risk of accidental ingestion by young children.
