CR2450 and CR2032 are button batteries used to small portable electrical devices like pocket calculators, remote controls, , wristwatches, implantable cardiac pacemakers, hearing aids, and other medical devices. Most electronic devices that use a require very little , which gives a longer service life. Both CR2450 and CR2032 batteries hold their charge for a long time if not used. They also have a low self-discharge. Here we will focus on the differences between the CR2450 vs CR2032 batteries, features, capacity, , and brands.
Even though these batteries are in the same CR-series family, they have different purposes.
Are there any safety concerns when using either battery type?
Next, we’ll begin with a comparison table and then show their features, and explain if the two batteries are interchangeable.
|Capacity||486 mAh||240 mAh|
|Voltage||3 V||3 V|
|Thickness||5.0 mm||3.2 mm|
|Diameter||24 mm||20 mm|
|Rechargeable||Not rechargeable||Not Rechargeable|
CR2450 vs CR2032 Capacity
The capacity of a is the amount of charge the can store. The chemical composition of and the size of the has a role to play in its capacity.
The has a capacity of 486 mAh. Using this on a that requires as little as 2mA , it can last for up to 243 hours . Meaning, this can last for more than ten days on a 2mA load.
The , on the other hand, has a capacity of 240 mAh. When we connect this to a load of 2 mA, it can last for up to 120 hours . Meaning, this can last around 5 days on a 2mA load.

CR2450 vs CR2032 Voltage
The voltage of a battery means a difference in charge between the two terminals of the battery, or the potential of the cell. The higher the potential of the cell, the higher the voltage.
The CR2450 is a 3 V button battery.
The CR2032 is a 3V button battery.
CR2450 vs CR2032 Thickness
The distance from the top to the bottom of the battery is the thickness of the cell. Another way to know how thick a CR-series battery is, with the name.
The last two digits of a cell’s name represent the thickness of the battery in a tenth of a millimeter.
The CR2450 is 5.0 mm thick.
The CR2032 battery is 3.2 mm thick.
CR2450 vs CR2032 Diameter
The diameter of a button battery is the distance of the cell from one end of the battery to the other end, passing through the middle. It is essential to know the diameter of a button battery because not all button battery comes with the same width.
The CR2450 is 24 mm wide.
The CR2032 cell is 20 mm broad
Not all button batteries are rechargeable. But there are claims that non-rechargeable batteries can be recharged by removing them from the device and inserting it in a battery charger. But take note that this process is not safe.
Are the CR2450 and CR2032 batteries rechargeable?
The CR2450 is not rechargeable, it is a disposable battery.
The CR2032 is not rechargeable either, it is a disposable battery.
CR2450 vs CR2023 FAQ
Are CR2450 and CR2032 interchangeable?
No, the CR2450 and CR2032 button batteries are not interchangeable. They have the same chemical types and output voltage.
However, despite being very similar to CR2032, the CR2450 batteries are wider and cannot be replaced interchangeably with CR2025 and CR2032 batteries.
CR2450 is also thicker and higher in capacity.
Alternatives and Equivalents to the CR2450 Battery
Instead of the C2450, you can also use rechargeable LiR2450 batteries. There are several subtypes of such button batteries depending on the voltage – 3.0V LiR2450, 3.2V LiR2450, 3.5V LiR2450, 3.7V LiR2450. As long as your device supports all the voltage levels (based on its technical description), you can use all the rechargeable LiR2450 batteries interchangeably with CR2450
The capacity of the rechargeable LiR2450 batteries is around 100-125 mAh. They can be recharged over 500 times.
Non-rechargeable alternatives to CR2450 include CR2430 and CR2477 button batteries. The three batteries all have the same diameter but different thicknesses – 3.0, 5.0, and 7.7 mm (which you can find out from their names).
Here are the capacities of the three possible alternatives:
- CR2430: 270-290 mAh,
- CR2450: 600-620 mAh,
- CR2477: ~1000 mAh.
Alternatives and Equivalents to the CR2032 Battery
Some possible alternatives to CR2023 button batteries are BR2032, ML2032, and LiR2032.
The BR2032 button battery has a Lithium Carbon Monofluoride chemistry. Carbon monofluoride is the positive electrode, while lithium is the negative one. It has a similar voltage to CR2023 of around 2.6-2.8 V. A substantial difference is that BR2032 doesn’t tolerate high discharge currents as well as CR2032 chemistry.
LiR2032 is a rechargeable lithium 3.6 V button battery of the same dimensions as CR2032.
ML2032 is also a based on chemistry. It is a Maxell’s , but other brands also produce it. One disadvantage is that it may overheat or even explode.
Good CR2450 & CR2032 battery brands
Some good brands producing CR2450 and/or CR2032 button batteries are Energizer, Duracell, Panasonic, Philips, EmazingLights, LiCB. Amazon Basic is also a good enough option.
