CR2450 Battery Equivalents
CR2450 batteries are non-rechargeable 3.0V lithium batteries, commonly used in devices and gadgets requiring relatively strong pulse currents and a battery with long operating life, like car key fobs, some medical and security devices, key chain flashlights, calculators, wearable electronics, and similar.
Thanks to the advancements in chemistry and technology in general, several similar batteries are available on the market, including CR2450, BR2450, LiR2450, etc. which can lead to confusion among the users.

CR2450 Battery Specifications and Features
CR2450 battery is based on the Lithium Manganese Dioxide (Li-MnO2) non-rechargeable chemistry and features physical dimensions of (D x W) 24.5 x 5.0 mm (~0.964 x 0.197 inches) - CR2450 battery is one of the largest lithium button/coin cell batteries, with only CR2477 (24.5 x 5.0 mm) having larger volume.
Note: CR3032 battery (30 x 3.2 mm) features a larger diameter, but the volume is smaller than the volume of the CR2450 battery.
A nominal voltage of the CR2450 battery is 3.0 volts, while the cutoff voltage is generally considered to be 2.0 volts - cutoff voltage also depends on the minimum voltage required by the device in order to function properly.
Nominal capacity depends on the discharge current, temperature, age, and similar, but on average CR2450 batteries feature a capacity of around 550-620 mAh.
While CR2450 batteries offer good capacity, large pulse currents, a rather broad temperature range, low-self discharge rate, other chemistries are also used in order to fill the gaps left by the CR2450 battery chemistry - other 24.5 x 5.0 mm battery chemistries include Carbon-Monofluoride Lithium batteries and Lithium-Ion batteries.
CR2450 batteries are manufactured by many brands and are often labeled using other labels as well, including 5029LC, DL2450, ECR2450, CR2450N, CR-2450, CR2450EL, CR-2450EL, and similar.
Carbon-Monofluoride Lithium 24.5 x 5.0 mm batteries are commonly labeled as BR2450 batteries - they are non-rechargeable batteries featuring ultra-low self-discharge rate, even broader temperature range than CR2450 batteries, but also somewhat smaller capacity.
Also, BR2450 batteries are not suitable for high current applications.
With their nominal voltage of 3.0V and cutoff voltage of 2.0V, BR2450 batteries are compatible with CR2450 batteries for use in low-drain applications - CMOS batteries, for example, but for high-drain applications, CR2450 batteries are the way to go.
Lithium-Ion 24.5 x 5.0 batteries are commonly labeled as LiR2450 batteries - they are rechargeable batteries featuring a nominal capacity of 100-120 mAh, a nominal voltage of 3.6-3.7 volts, and a cutoff voltage of 2.7-3.0 volts.
Although LiR2450 batteries feature a capacity that is 5-6x smaller than the capacity of the CR24350 battery, LiR2450 batteries support hundreds of charging/discharging cycles and are able to provide much stronger constant discharge currents.
However, due to the voltage difference, LiR2450 and CR2450 batteries are not directly compatible, unless explicitly expressed by the manufacturer of the device being powered by the CR2450 battery.
Note: LiR2450 batteries should be recharged only with the battery chargers intended for such batteries.

As one can see, CR2450 batteries feature a very long shelf life (some models 10+ years), good capacity, are able to provide strong pulse currents, have a broad operating temperature range, etc.
BR2450 batteries are rare these days, but for special applications, they do offer some benefits over CR2450 batteries.
LiR2450 batteries are able to provide up to 50-120 mA max. continuously, which is much more than the typical 3 mAh max. continuously of the CR2450 batteries.
CR2450 Battery Frequently Asked Questions (FAQ)
Here are some of the most common Frequently Asked Questions about CR2450, BR2450, and LiR2450 batteries:
Can I use CR2450 instead of BR2450?
Yes, the CR2450 battery can be used instead of the BR2450 battery if the operating temperature of the CR2450 battery fits the operating range of the BR2450 battery application.
Also, if it is a very low drain application, it is possible that the CR2450 battery will not last as long as the BR2450 battery, not because of the drain current, but because of the higher self-discharge rate.
What battery is the same as CR2450?
CR2450 batteries are also commonly labeled as 5029LC, DL2450, ECR2450, CR2450N, CR-2450, CR2450EL, CR-2450EL and similar.
What is a CR2450 battery used for?
CR2450 batteries are used as CMOS batteries, as car key fob batteries, for powering wearable electronics, some medical and security devices, in some toys, calculators, compact LED flashlights, etc.
Can I use a CR2430 battery instead of a CR2450 battery?
Although the CR2430 battery can fit a battery compartment intended for a CR2450 battery, note that the CR2450 battery features lower capacity and can have contact issues in such battery compartment - for short, no!
Long Story Short: If You are looking for a lithium non-rechargeable 24.5 x 5.0 mm battery, go for the CR2450 battery from reputable brands with many positive reviews - such batteries have already been tried and tested by many users in various real-life situations.
Only if You have a very specific application, check exactly what battery You need and go for BR2450 or LiR2450 battery/batteries, with or without soldering tabs.
