The CR2032 battery is a non-rechargeable lithium coin or “button” cell known for its 20mm diameter and 3mm thickness. This type of battery, such as the Duracell Specialty 2032, utilizes manganese dioxide lithium chemistry, offering a voltage of 3 volts and a typical capacity of 225 mAh. Renowned for its 70% extra life compared to previous versions, the CR2032 is a reliable choice for various applications.
Due to its widespread use, the CR2032 battery has several aliases depending on the manufacturer, including 5004LC, BR2032, DL2032, ECR2032, KCR2032, and KECR2032. It’s especially suitable for devices like watches, small clocks, doorbells, and car key remote control fobs. This battery type also powers 3D TV active shutter glasses, CMOS motherboards, and certain scientific instruments. The battery often comes in a pack of five, each with a nominal capacity of 220mAh and an operational temperature range of -10C to 60C. In intermittent power devices, such as remote controls, a CR2032 battery may last up to eight weeks.
Among its many versions, the EXTRASTAR CR2032 stands out for its alkaline 3V non-rechargeable lithium design, suitable for keyfobs, toys, medical devices, and calculators. The CR2032 coin cell battery excels in high energy density and consistent performance in extreme temperatures, ranging from -30C to 85C. For example, the BR-2032/BN variant is a poly-carbon mono-fluoride lithium battery with pressure contact terminals, widely used in car security, PDAs, glucometers, and electronic watches.
The Energizer brand promises a long service life and reliable power supply for various appliances. These batteries can hold power for up to 12 years in storage and withstand temperatures from -30º to 60ºC. They also have a superior storage reserve capacity of 235 mAh compared to the CR2025’s 170 mAh, delivering dependable performance in heart rate monitors, remote controls, and glucose monitors.
GP CR2032 batteries come in a pack of 10, each individually removable, and are ideal for use in a wide range of devices. New Lon0167 offers a unique 2x3V CR2032 plastic housing for the coin cell button battery, ensuring safety and convenience. It’s crucial to keep new and used coin-sized button batteries away from children’s reach to prevent accidental ingestion.
Duracell’s Specialist Electronic Battery is another notable variant, ideal for calculators and cameras. Powerowl’s CR2032 3V batteries cater to keyfobs, scales, wearables, and sensors, emphasizing the versatility of the CR2032 across various electronic devices.
