Thanks to its high demand and also many manufacturers that offer these batteries, there is slight confusion regarding CR2032 battery equivalents and replacements.

No wonder, since one can find batteries labeled together CR2032, DL2032, BR2032, ML2032, LiR2032, LR2032, E-CR2032, SB-T51, 5004LC, etc.

But, these batteries feature the very same dimensions, but additionally different chemistries, result in various discharge characteristics.

*

According come the standard, the CR2032 battery is 20 mm in diameter and also 3.2 mm in height - hence the "2032" component of the name. On average, this batteries weigh about 2.5 and 3.0 grams, v the usual CR2032 weighing about 2.9 grams.

Nominal voltage, cut-off voltage, capacity, operating and also storage temperature ranges, recommended and also maximum drainpipe currents and also other features depend top top the exact chemistry of this batteries.

CR2032 Battery Features and also Specifications

*
CR2032 battery is based upon Lithium Manganese Dioxide (LiMn02) chemistry. The confident electrode is manganese dioxide and the negative electrode is lithium.

The in the name voltage the the CR2032 battery is 3.0 V and the cutoff voltage is 2.0 V, through a typical capacity in the 210-230 mAh range.

CR2032 operation temperature range is generally in between -20°C (-4°F) and +70°C (158°F) - through the advancements in chemistry and also metallurgy, the operation temperature selection of some newer models is also broader.

CR2032 battery"s typical maximum discharge present is ~3mA through a best pulse discharge present of ~15 mA.

Although the nominal voltage of the CR2032 battery is 3.0 V, it conveniently drops come 2.7-2.8 volts in real-life applications. The self-discharge rate is very low (sometimes even Amazon Search:

BR2032 Battery vs CR2032 Battery

BR2032 battery is based upon Lithium Carbon Monofluoride chemistry. The hopeful electrode is carbon monofluoride and also the an unfavorable electrode is lithium.

The nominal voltage the the BR2032 battery is ~2.8 V, and also a cutoff voltage is ~2.25 V, through a common capacity in the 180-190 mAh range. However, more recent BR2032 battery often function a in the name of voltage of 3.0 volts and also a cutoff voltage that 2.0 volts.

BR2032 operation temperature range is in between -30°C (-22°F) and also +85°C (185°F), back there are models that feature operating temperature variety from -40°C (-40°F) to +125°C (257°F) - and that is a lot.

Although a usual voltage of 2.8 V is somewhat smaller sized than CR2032"s 3.0V, in real-life applications it drops to 2.6 - 2.7 V, i beg your pardon is just slightly lower than CR2032"s 2.7-2.8 V. More recent BR2032 functions nominal voltage throughout low-drain applications very comparable to the voltage of CR2032 batteries. Also, the actual voltage throughout low-drain use over several years is even an ext stable than the voltage that CR2032 batteries.

BR2032 doesn"t pardon high discharge currents as great as CR2032 chemistry and also it is not the best selection for applications the periodically require relatively huge currents, choose key-chain flashlights, remote devices, watches v alarms and also LED lights, and also similar.

But, because that applications the require constant voltage over a longer period of time, and over a broad range of temperatures, BR2032 is a better choice 보다 the CR2032 battery.

ML2032 Battery vs CR2032 Battery

ML2032 battery is Maxell"s rechargeable Manganese Dioxide Lithium through 3.0 V in the name of voltage. That is offered in specific electronic devices like solar charging Logitech K750 wireless keyboard and similar.

ML2032 battery are additionally manufactured by other brands together well.

ML2032 battery are typically recharged by the an equipment where lock are supplied - if they space recharged v the battery charger, the battery charger have to be intended for these batteries, or they may be overcharged, regularly leading come overheating and also even fire/explosion.

LiR2032/LR2032 Battery vs CR2032 Battery

LiR2032 or LR2032 battery is rechargeable lithium 3.6 V battery. Simply like any other standard 2032 battery, the is 20 mm in diameter and 3.2 mm in height.

LiR2032 battery in the name voltage is 3.6-3.7 V, but it additionally depends ~ above the precise chemistry (lithium cobalt oxide, lithium manganese oxide, lithium stole phosphate, lithium nickel cobalt aluminum oxide, etc.) and also varies indigenous 3.2 come 3.7, through some chemistries also having a in the name of voltage of 3.9 volts.

The in the name of cut-off voltage is 2.6 V, but it varies from 2.0 to 3.0 V. Maximum charging voltage also differs, and also it is in the 3.65 come 4.3 volts range.

Note: common LiR2032 battery is 3.6 V battery, with typical capacity in 35-50 mAh range. Their volume is obviously reduced than CR2032"s typical 220 mAh capacity, however LiR2032 batteries deserve to be recharged 500+ times.

Modern LiR2032 batteries function a fairly low self-discharge rate when compared with NiCd and NiMH batteries, however still, their discharge price is much higher than the self-discharge rate of CR2032 and especially BR2032 batteries.

LiR2032 batteries require special battery chargers i m sorry are frequently powered via USB cable and also are capable of charging other comparable lithium-ion batteries.

CR2032 Battery safety and security Issues

Modern CR2032 battery don"t save on computer mercury, cadmium, and comparable toxic metals, yet nonetheless, as soon as they are discharged, they need to be recycle properly.

Also, CR2032 batteries space small, shiny objects the can attract kids and pets - although they room not the the smallest button/coin-cells top top the marketplace, they can obtain swallowed.

That is why CR2032 and similar batteries room packaged in "kids safe packages.

But, if they obtain swallowed, castle can cause chemical burns resulted in by electrolysis, which deserve to be really dangerous, even deadly.

If CR2032 or any kind of other comparable battery gets swallowed, instantly contact the nearest emergency center, describe to castle what happened, and act according to their instructions... This is a significant warning!

For Short: If you require a 2032 button/coin cell battery, regardless of its label (CR2032, DL2032, BR2032, ML2032, LiR2032, LR2032, E-CR2032, SB-T51, 5004LC, etc.) take into consideration the following:

- CR2032: 3.0 V in the name voltage, an excellent drain currents, lengthy shelf life, ~220 mAh capacity,

- BR2032: 2.8-3.0 V in the name of voltage, low drain currents, extra-long shelf life, large operating temperature range, ~190 mAh capacity,

- LiR2032: 3.6 V nominal voltage, rechargeable, great drain currents, reasonably high self-discharge rate, ~50-70 mAh capacity.
