content: The dl2032 and cr2032 batteries are slightly different in terms of capacity, weight, and operating temperature. The former has a capacity of 235mAh, while the latter has a capacity of 225mAh. In addition, the dl2032 is 5g heavier than the cr2032 and has a wider operating temperature range.The dl2032 and cr2032 are not so different that replacing them with each other will not cause any problems and they can be used universally. Although there are some variations, they do not have any significant impact on the battery characteristics. Both batteries offer the same nominal voltage and have almost similar capacities.Although the dl2032 and cr2032 are very similar and almost universal. But dl2032 vs cr2032, the former is more suitable for high current consumption applications.

content: DL is Duracell. It's a marketology gimmick. CR is better, it is rechargabal and cheaper.

content: Quote from: u666sa on December 11, 2023, 07:13:56 amThat's not quite correct. There are rechargeable and disposable Cr2032 btteries. A Rechargeable 2032 lithium will state on the battery case that it is rechargeable. If there is no rechargeable marking then it is disposable. You should not attempt to recharge a disposable lithium battery.

content: CR2032 is not rechargeable, usually.There's also BR2032 made by Panasonic, using Lithium Poly-Carbon Monofluoride chemistry, nothing significantly special ... 200mAh , 0.03mA continuous discharge..https://industrial.panasonic.com/cdbs/www-data/pdf2/AAA4000/AAA4000C222.pdfFor rechargeable, Panasonic uses ML as prefix , for example ML2020, for manganese lithium ... seehttps://www.digikey.com/en/products/detail/panasonic-bsg/ML-2020-V1AN/431504There's also VL , Vanadium Pentoxide Lithium , for exmaplehttps://www.digikey.com/en/products/detail/panasonic-bsg/VL-2020-HFN/119936

content: Last time I really looked deep into rechargeable 2032 style coin cells the rechargeables were about 95mah vs. 225mah for the disposables. And as stated before a CR is a disposable, other prefixes indicate rechargeable although some said 'Replaces CR2032' etc.

See below.Quote from: mariush on December 11, 2023, 09:15:55 amCR and BR are not proprietary Panasonic naming, they’re the designations under the IEC designations for electrochemical systems:https://en.wikipedia.org/wiki/Battery_nomenclatureA BR cell is, by definition, a primary lithium cell with a carbon monofluoride cathode and an organic electrolyte.A CR cell is, by definition, a primary lithium cell with a manganese dioxide cathode and an organic electrolyte.Rechargeable cells aren’t within this system and have their own designations, like LIR2032.

content: Tooki, you are right on the money with the LIR2032!!! That is exactly what we used on motherboards for bios backup and had a trickle charge circuit for when the unit was powered on.
