ML2032 batteries are also manufactured by other brands as well.
It is used in certain electronic devices like solar charging Logitech K750 wireless keyboard and similar. ML2032 battery is Maxell's rechargeable Manganese Dioxide Lithium with 3.0 V nominal voltage. It is not the best choice for applications that periodically require relatively large currents, like key-chain flashlights, remote devices, watches with alarms and LED lights, and similar.īut, for applications that require constant voltage over a longer period of time and over a broad range of temperatures, BR2032 is a better choice than the CR2032 battery. Also, the actual voltage during low-drain use over several years is even more stable than the voltage of CR2032 batteries.īR2032 doesn't tolerate high discharge currents as well as CR2032 chemistry. Newer BR2032 features nominal voltage during low-drain applications very similar to the voltage of CR2032 batteries. However, newer BR2032 batteries often feature a nominal voltage of 3.0 volts and a cutoff voltage of 2.0 volts.īR2032 operating temperature range is between -30☌ (-22☏) and +85☌ (185☏), although there are models that feature operating temperature range from -40☌ (-40☏) to +125☌ (257☏) - and that is a lot.Īlthough a typical voltage of 2.8 V is somewhat smaller than CR2032's 3.0 V, in real-life applications, it drops to 2.6 - 2.7 V, which is just slightly lower than CR2032's 2.7-2.8 V. The nominal voltage of the BR2032 battery is ~2.8 V, and a cutoff voltage is ~2.25 V, with a typical capacity in the 180-190 mAh range. The positive electrode is carbon monofluoride, and the negative electrode is lithium. CR2032 BatteryīR2032 battery is based on Lithium Carbon Monofluoride chemistry. Note: Many manufacturers simply print on the battery label all the types that their battery replaces, somewhat increasing the confusion but often helping the users find the battery they need. The self-discharge rate is very low (sometimes even <1% annually), and the CR2032 battery is often used for nonvolatile computer BIOS memory and real-time clock (RTC) backup batteries.ĬR2032 batteries from reputable brands feature a shelf-life of up to 7-10 years. The nominal voltage of the CR2032 battery is 3.0 V, and the cutoff voltage is 2.0 V, with a typical capacity in the 210-230 mAh range.ĬR2032 operating temperature range is generally between -20☌ (-4☏) and +70☌ (158☏) - with the advances in chemistry and metallurgy, the operating temperature range of some newer models is even broader.ĬR2032 battery's typical maximum discharge current is ~3 mA with a maximum pulse discharge current of ~15 mA.Īlthough the nominal voltage of the CR2032 battery is 3.0 V, it quickly drops to 2.7-2.8 volts in real-life applications. The positive electrode is manganese dioxide, and the negative electrode is lithium.
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.
