Battery Equivalents and Replacements

Lithium CR2025, DL2025, E-CR2025, SB-T14, 5003LC, BR2025, LiR2025 Battery Equivalents

cr2025 batteryLithium CR2025 is very popular lithium 3.0 V non-rechargeable battery, often used in car remote keys, watches, medical equipment, calculators, remote control devices, keychain LED lights and other small electronic devices. Due to its very long shelf life and stable voltage, CR2025 is often used as memory battery in computers, cameras and other electronic devices.

Thanks to its high demand, many manufacturers offer these batteries with various labels,  creating slight confusion regarding CR2025 battery equivalents and replacements. Often CR2025 batteries are labeled as CR2025, DL2025, E-CR2025, SB-T14, 5003LC, BR2025, LiR2025 etc.

CR2025 battery is 20 mm in diameter and 2.5 mm in height, thus the '2025' part of the name.

Its features like nominal voltage, cut-off voltage, operating and storage temperature ranges, capacity, recommended and maximum drain currents and other features depend on the chemistry of these batteries.

dl2025 batteryCR2025 battery is based on Lithium Manganese Dioxide (LiMn02) chemistry, with positive electrode being made of manganese dioxide and negative electrode being made of lithium.

Nominal voltage of CR2025 battery is 3.0 V and cut-off voltage is 2.0 V, with typical capacity in the 160-170 mAh range, and typical discharge current of ~0.2mA.

Although nominal voltage of CR2025 battery is 3.0 V, it quickly drops to 2.7-2.8 volts in real life applications. Self-discharge rate is very low and the CR2025 battery is often used for the real-time clock (RTC) backup batteries and as the nonvolatile computer BIOS memory battery.

CR2025 operating temperature range is between -4°F (-20°C) and 158°F (70°C).

Manufacturers of CR2025 and similar batteries often print on the package type of the battery (CR2025), but also all the possible types that their battery replaces like 2025, CR2025, DL2025, DL2025B, ECR2025, KCR2025, BR2025, SB-T14, LF12V, 5003LC, BR2025-1W, CR2025-1W, L12, LM2025, 208-205 etc. Such practice can lead to slight confusion, but it also helps the user to find the right battery replacement.

BR2025 battery is based on Lithium Carbon Monofluoride chemistry. Positive electrode is carbon monofluoride and negative electrode is lithium.

Nominal voltage of BR2025 battery is 2.8 V, and a cutoff voltage is 2.25 V, with typical capacity in the 130-150 mAh range, which is somewhat lower than CR2025 capacity of 160-170 mAh.

BR2025 operating temperature range is between -22°F (-30°C) and 185°F (85°C), which is broader range than CR2025's temperature range of -4°F (-20°C) and 158°F (70°C).

Although typical voltage of 2.8 V is smaller than CR2025's 3.0V, in real life applications it drops to 2.6 - 2.7 V, which is just slightly lower than CR2025's typical operating voltage of 2.7-2.8 V.

BR2025 doesn't tolerate high discharge currents well and is not the best 2025 battery for applications that periodically require relatively large currents, like key-chain flashlights, remote devices and similar.

But, for applications that require constant voltage over longer period of time and over broad range of temperatures, BR2025 is better choice than CR2025 battery.

lir2032 battery chargerLiR2025 or LR2025 battery is rechargeable lithium 3.6 V battery. Just like any other standard 2025 battery, it is also 20 mm in diameter and 2.5 mm in height.

LiR2025 battery nominal voltage is 3.6 V, but its nominal voltage also depends on the used chemistry (lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, lithium nickel cobalt aluminum oxide, etc.) and it varies from 3.2 to 3.9 volts.

Nominal cut-off voltage is 2.6 V, but varies from 2.0 to 3.0 V. Also, maximum charging voltage differ, and it is in the 3.65 to 4.3 volts range.

Note: Common LiR2025 battery is 3.6 V battery, with typical capacity around 30-40 mAh. Their capacity is obviously lower than CR2025's average 165 mAh capacity, but LiR2025 batteries can be recharged 500-1000x, sometimes even more.

Modern LiR2025 batteries feature relatively low self-discharge rate, when compared with NiCd and NiMH batteries, but their discharge rate is still much higher than self-discharge rate of CR2025 and especially BR2025 batteries.

LiR2025 batteries require special charger which are often powered via USB cable and are capable of charging other similar lithium ion batteries, like CR2016, CR2020, CR2032 etc.

CR2025/BR2025 vs LiR2025 Batteries

LiR2025 batteries are very cost-effective solution for watches, medical devices and other electronic devices that use 2025 batteries, that tolerate 0.6V nominal voltage difference and that drain the batteries quickly enough that the use of rechargeable batteries make economic sense.

lir2025 battery

Math Example:

A good CR2025 battery comes with 160-170 mAh capacity, when drained for 20 hours.

A good LiR2025 battery comes with 30-40 mAh capacity, when being discharged for 20 hours.

If we assume that CR2025 battery has 160 mAh capacity and LiR battery has 40 mAh capacity, but can be recharged for 500 times (in real life, good LiR batteries can tolerate even larger number of charging/discharging cycles), actual 'usable' capacity of LiR2025 capacity is:

40 mAh x 500 = 20000 mAh = 20 Ah

which is some 125x larger 'usable' capacity than the capacity of common CR2025 battery.

This 125x difference is huge, justifying the use of LiR2025 batteries in high drain devices.

On the other hand, LiR2025 batteries should not be used for computer BIOS memory and similar applications where constant, uninterrupted voltage is require for years - in such situations consider good CR2025 or BR2025 battery.

E-CR2025, DL2025 and other similar batteries are often just a 'standard' CR2025 battery, but having customized label by their manufacturer. Again, to promote their products, manufacturers of CR/BR/LiR2025 batteries print down all the battery labels that their batteries replace. Just read the labels ... :)

The Difference Between CR2025 and CR2032 - CR2025 vs CR2032

If you wonder, are CR2032 and CR2025 batteries interchangeable batteries, answer is not that simple.

Main difference between these two batteries is in height (2.5 mm vs 3.2 mm), leading thus to the difference in capacity, regardless of the chemistry:

- 165 mAh vs 225 mAh for CR2025/CR2032 batteries (Lithium Manganese Dioxide (LiMn02) chemistry),

- 145 mAh vs 180 mAh for BR2025/BR2032 batteries (Lithium Carbon Monofluoride chemistry),

- 30 mAh vs 50 mAh for LiR2025/LiR2032 batteries (rechargeable lithium batteries).

Drain currents are not so different, they are either the same or 2032 batteries have slightly larger drain currents.

Problem with these batteries is the height difference of 0.7 mm (one 36th of an inch). This doesn't sound much, but some devices that are designed for 2025 battery simply can't accept 2032 battery.

Also, devices that are designed for 2032 battery can accept 2025 battery, but in some instances contacts between 2025 battery and terminals on the devices can be loose due to the 0.7 mm battery height difference, leading to the power issues due to the vibrations and similar.

On the other hand, some devices are certified for both 2025 and 2032 batteries - in such case, go for good 2032 battery just for the sake of larger capacity. If larger capacity is required at all ...

For Short: If you need 2025 button/coin cell battery, regardless of its label consider following:

- CR2025: 3.0 V nominal voltage, good drain currents, long shelf life, ~165 mAh capacity,

- BR2025: 2.8 V nominal voltage, low drain currents, extra long shelf life, operates at extreme low and high temperatures, ~140 mAh capacity,

- LiR2025: 3.6 V nominal voltage, rechargeable, good drain currents, relatively high self-discharge rate, ~30-40 mAh capacity.

If you need non-rechargeable 2025 battery and you are not sure which one to take, consider CR2025 battery from reputable brands with good reviews and you will do just fine.
