CR2450 vs. CR2032: Are they interchangeable?

Lithium 3.0V CR2450 battery is a non-rechargeable button/coin cell battery commonly used in watches, computer motherboards, medical devices, LED flashlights, toys, remote controls, car remote keys, security systems, wearable electronics, and among others.

CR2450

A CR2032 battery is a 20mm diameter x 3.2mm thickness non-rechargeable (primary) lithium coin or "button" cell battery. Depending on the manufacturer, the CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh. The CR2032 is the most widely used lithium coin cell battery today. The CR2032 battery is used in a variety of commercial applications, including automobile key fobs, motherboards, security system panels, and weapons sighting systems. The CR2032 battery can also be fitted with connecting tabs, allowing it to be installed in practically any position.

The following is the specification between CR2450 and CR2032.

The benefits and features are shown in the following.

CR2450 Equivalent:

CR2032 Equivalent:

The CR2025 battery is a very common lithium coin cell battery that is used in the same quantities and for the same purposes as the CR2032. The CR2025 is marginally more suited for goods with limited mounting space than the CR2032.

CR2450 Battery:

The Lithium Coin CR2450 batteries have several advantages in applications where standard batteries are ineffective. Calculators, digital watches, laser pens, vehicle keys, medical devices such as a clinical thermometer and a tensiometer, and workout equipment can all be stored in them.

CR2032 Battery:

Lithium Coin CR2032 has some advantages for devices that can't use regular batteries. Memory backup, digital watches, car keys, laser pens, fitness gadgets, and medical devices such as tensiometers and clinical thermometers can all benefit from this battery.

If swallowed, the CR2450 battery, like all other lithium batteries, can be extremely dangerous, not because of the toxic elements (CR2450 batteries are typically free of mercury, lead, cadmium, and other heavy metals), but because of the electrolysis, which can cause severe internal injuries and burns.

If a battery, whether a CR2450 or another, is ingested, contact your local emergency center and follow their instructions, such as inducing vomiting.

As a result, most manufacturers package CR2450 and comparable batteries in 'child safe' packaging. But, just in case, keep batteries out of reach of children and dogs.

The CR2450 is frequently compared to the widely used lithium 3.0 volts CR2032 battery. For the same chemistry types, the output voltages of these batteries are the same.

The CR2450 battery uses the same type of storage as the CR2032 battery. As a result, the energy density is the same, but the capacity of the CR2450 cell is greater due to its bigger size. The capacity varies by manufacturer and is typically around 620 mAh.
