![]() ![]() Of course, there are certain limitations in performance at extreme temperature ranges. The operating temperature of CR1632 batteries is usually in the -20☌ to 60☌ range, with some models being able to withstand temperatures between -30☌ and 85☌, with some models supporting temperatures between -40☌ and +125☌. ![]() Manganese-dioxide lithium chemistry tolerates well pulse drain applications (for example, wrist watches with alarms or LED lights, key fobs, and other medical devices), but the frequent use of such applications may shorten operating life significantly. Similarly, the nominal capacity of the CR1632 batteries is around 120-140 mAh, with the standard discharge current being around 0.1-0.2 mA.Īctual capacity depends on the temperature and the drain current. However, cutoff voltage often depends on the cutoff voltage of the device being powered by a CR1632 battery. Note: rechargeable 3.0V ML1632 batteries, and especially VL1632 batteries, are very rare, but we mention them just in case.ĬR1632 battery is an "official" label (according to IEC standard), but there are other labels in use as well, like DL1632 (by Duracell), ECR1632 (by Energizer), and similar.ĬR1632 battery features a nominal voltage of 3.0 volts and a cutoff voltage of ~2.0 volts. It should not be confused with rechargeable 3.0V manganese lithium chemistry, labeled as an "ML" battery, or rechargeable 3.0V vanadium lithium batteries, labeled as a VL1632 battery. Letters "CR" means that it is a round battery (hence "R") and features a non-rechargeable manganese-dioxide lithium chemistry. Lithium CR1632 battery features physical dimensions of (D x H) 16.0 x 3.2 mm (~0.63 x 0.126 inch), hence the "1632" part of its label. Lithium CR1632 Battery Features and Specifications But, it also comes with different labels, causing some confusion among the users. ![]() It is quite a common battery and easy to obtain. Lithium CR1632 battery is a very popular battery, commonly used in car keys, remote devices, toys, calculators, digital watches, CMOS battery, and similar. Lithium CR1632 battery is a non-rechargeable button/coin cell battery based on the manganese-dioxide lithium chemistry, featuring a nominal voltage of 3.0 volts. ![]()
