CR2450 Battery Features

Size and Dimensions

The CR2450 battery is round and flat. It is 24.5 millimeters wide and 5 millimeters thick. In inches, it is about 0.96 wide and 0.20 tall. This size is good for small devices that need a small battery.

Other coin cells have the same width, but not the same thickness. The CR2450 is thicker than the CR2430 and CR2032. It is not as thick as the CR2477. You can see the size differences in the table below:

The CR2450’s extra thickness lets it hold more energy. This means it lasts longer in devices.

Voltage and Capacity

The CR2450 gives 3 volts of power. This voltage stays steady most of the time. Big brands like Panasonic say it holds 500 to 620 mAh. Most CR2450 batteries have about 600 mAh. This high number means it can power things for a long time.

The CR2450 has a lot of energy in a small size. Its voltage stays steady and it has low resistance. This helps devices work well. Devices like medical tools and fitness trackers need this steady power.

Chemistry and Shelf Life

The CR2450 uses lithium manganese dioxide chemistry. This gives it 3 volts and helps it last a long time. It loses only about 1% of its power each year. So, it can sit unused for years and still work.

Note: The CR2450 can last up to 10 years in storage if kept at normal temperatures. Its special design and electrolyte help stop leaks and keep it safe.

The battery works in many places. It can work from -30°C to 60°C (-22°F to 140°F). This means it works in both cold and hot weather.

Some features that help the CR2450 work well are:

A strong case and special electrolyte to stop leaks.
Steady voltage when used.
Chemistry that gives a long shelf life and steady power.
It works in many temperatures.

The CR2450 is not rechargeable. You must replace it when it runs out.

Common Devices

Many small gadgets use the CR2450 battery for power. It gives steady energy and lasts a long time. Its high capacity and steady voltage make it popular. People use it in both daily and special devices. Here are some common things that use this battery:

Medical devices (like glucose monitors and health monitors)
Fitness trackers and wearable gadgets
Digital thermometers
LED flashlights and laser pointers
Watches and advanced digital watches
Keyless entry remotes and car keys
Computer motherboards (for memory backup)
Wireless sensors and smart home devices
Remote controls and garage door openers
Industrial tools and asset tracking systems

Note: The CR2450 battery is good for devices that need more power than smaller coin cells. Its bigger capacity means you do not have to change it as much. This helps with devices you use every day or ones that are hard to reach.

The table below shows how the CR2450 works in different devices compared to other coin cells:

Advantages in Applications

The CR2450 battery is great for devices that need steady power. Its high capacity, up to 620 mAh, lets things run longer before you need a new battery. This is important for medical devices, fitness trackers, and sensors that must always work.

The battery keeps a steady 3V output, so devices work well.
Its lithium manganese dioxide chemistry gives it a long shelf life, up to 10 years. It can sit unused and still work when needed.
The CR2450 resists leaks and works in very hot or cold weather. This makes it good for outdoor sensors, emergency gear, and car tools.
Makers pick this battery because it is strong and gives reliable power. It means fewer battery changes, which saves time and effort.
Its size lets it fit in small devices but still gives more energy than smaller coin cells like the CR2032.

The CR2450 often works better than other batteries in devices that use a lot of power. It lasts longer and gives steady voltage. This matters for things like medical tools, security systems, and smart home sensors. Its design also meets safety and environmental rules, so many people trust it.

Comparison and Safety

CR2450 vs. Other Coin Cells

The CR2450 stands out among coin cell batteries because of its size and power. It has a larger diameter and thickness than both the CR2032 and CR2430. This means it can store more energy and last longer in devices. The table below shows the main differences:

The CR2450 battery offers the highest capacity. Devices that need more power or longer life often use this model. The CR2032 and CR2430 are smaller and hold less energy, so they are not good replacements for the CR2450.

Compatibility

Most devices need a specific battery size. The CR2450 battery is not interchangeable with smaller coin cells like the CR2032 or CR2430. Using a smaller battery can cause the device to stop working or run out of power quickly. Some key points about compatibility include:

The CR2450 fits only in devices made for its size and thickness.
Using a CR2032 or CR2430 in place of a CR2450 can cause contact problems and shorter battery life.
Rechargeable versions, like LiR2450, have a higher voltage and should not be used unless the device allows it.
The CR2450 matches with other model numbers such as DL2450, ECR2450, and LM2450.
Always check the device manual before changing the battery.
