CR2032 Battery Features and SpecificationsĬR2032 battery is based on Lithium Manganese Dioxide (LiMn0 2) chemistry.
Nominal voltage, cut-off voltage, capacity, operating, and storage temperature ranges, recommended and maximum drain currents, and other features depend on the exact chemistry of these batteries. On average, these batteries weigh around 2.5 and 3.0 grams, with the typical CR2032 weighing around 2.9 grams. No wonder, since one can find batteries labeled as CR2032, DL2032, BR2032, ML2032, LiR2032, LR2032, E-CR2032, SB-T51, 5004LC, etc.īut, these batteries feature the very same dimensions but also different chemistries, resulting in different discharge characteristics.Īccording to the standard, the CR2032 battery is 20 mm in diameter and 3.2 mm in height - hence the '2032' part of the name. Thanks to its high demand and many manufacturers that offer these batteries, there is slight confusion regarding CR2032 battery equivalents and replacements.
Due to its very long shelf life (5-10+ years) and stable voltage, it is often used as a memory battery in computers, servers, cameras, and other high-end electronic devices. Lithium CR2032 is a very popular non-rechargeable lithium 3.0 V battery, often used in watches, calculators, medical equipment, remote controls, and other smaller electronic devices. LIR2032 batteries are frequently used in car security systems, memory backup batteries in electronic devices, electronic watches, and many other applications.Lithium CR2032, DL2032, BR2032, ML2032, LiR2032, LR2032 Batteries - Equivalents and Replacements This chemistry is rechargeable, however a protective circuit is absolutely necessary due to the very high energy density of this type of cell. Unlike the other chemistries, the LIR chemisty has a voltage of 3.6V instead of 3V. Can be recharged at any point in the charge cycle.You don’t need to empty the charge before recharging.
2032 BATTERY LIFE FULL
Batteries with the VL designation have no memory effect, meaning they can be charged to full capacity at any point in the charge cycle. Use a lithium/aluminum alloy in the electrodeĪ Lithium Ion chemistry that works well in camcorder and rechargeable electronics applications.This new configuration makes the ML chemistry type ideal for cell phones and other small communications devices. The ML battery type also uses Lithium Manganese Dioxide but instead of using the manganese oxide compound in the negative electrode, it is used in the positive electrode. Usually discharge less than 0.5% each year.Have been used in space applications since 1976.That’s why they are commonly used in clocks, pacemakers, and not surprisingly, long range missiles. They have one of the slowest self-discharge rates of any battery on the market. BR batteries often last 7 years on the shelf. Batteries with this kind of chemistry are well known for their superior shelf life. Discharge quickly and evenly (for a camera flash)īR denotes Lithium/Carbon Monofluoride Li-(CF)x.Can handle low temperatures relatively well.Work well in digital cameras and computer peripherals.Provide a high density charge in a small package.Anything that requires a small high-powered battery probably uses Lithium Manganese Dioxide chemistry. CR batteries are also used in smoke alarms and security applications. These kinds of batteries are often used in cameras because of their high energy density and ability to perform in low-temperature environments.
In this brief article, we’ll decode the abbreviations and show you the advantages of different battery chemistry types.ĬR denotes Lithium Manganese Dioxide (LiMn02). Each battery chemistry performs better in certain situations as opposed to others. There are a few common battery chemistries that have an effect on a battery’s energy density, performance under varying temperatures, shelf life, rechargeability, and gravimetric capacity.
