We use compact power sources more than ever in today’s technology-driven world. From small-sized electronic gadgets to more advanced wearables, batteries are the devices that keep our lives powered and connected. Out of so many coin cell batteries available in the market, Sealed Energy’s CR2430 lithium coin battery holds a prominent position due to its high capacity, long shelf life, and stable performance.
What is a CR2430 Coin Cell battery?
The CR2430 Coin Cell battery is a 3V lithium coin cell known for its powerful and long-lasting performance. The “CR” in its name refers to its chemical composition—lithium manganese dioxide (Li-MnO₂)—which provides a stable voltage output and excellent energy density.
This makes it slightly thicker than smaller variants like the CR2032 or CR2025, offering more internal space for active materials and therefore a higher capacity.
Why choose the CR2430 Coin Cell battery?
Due to its balance between size and capacity, and voltage stability, the CR2430 battery has been a favorite for many manufacturers and users. Here are some of the reasons why it is outstanding:
a. High capacity for extended use
With a capacity of roughly 270–300 mAh, the CR2430 contains more energy compared to coin cells like the CR2032. This, in turn, allows devices to run longer in between replacements, and it becomes most suitable for applications needing constant power over longer durations.
b. Stable 3V Output
The 3-volt output maintains a consistent energy supply to prevent any sudden drops that may make your device malfunction. This stability is important for sensitive electronics, like medical instruments and cameras.
c. Wide Operating Temperature Range
From cold outdoor to warm indoor applications, the CR2430 provides consistent performance. Operating over a wide temperature range from -30°C to +60°C, it works in various conditions and applications in consumer and industrial devices.
d. Long Shelf Life
The low self-discharge rate of the CR2430 battery allows it to retain most of its charge for up to 10 years in storage, which of course makes it perfect for devices that are used intermittently or kept as emergency backups.
e. Leak-Resistant Design
With a sealed stainless-steel construction, leakage is minimal, hence ensuring safety for both the device and users.
Common Applications for the CR2430 Battery
The versatility of the CR2430 lithium coin cell makes it appropriate for a wide variety of everyday and specialized devices. Common applications include:
a. Cameras and Photography Equipment
Internal power for many compact cameras and light meters comes from the CR2430. The stable voltage ensures that light meters, exposure meters, and camera memory functions operate with accuracy.
b. Calculators and Measuring Instruments
From scientific calculators to digital measuring instruments, the steady power from a CR2430 delivers long-running, reliable operation.
c. Handheld Game Consoles
The high capacity of the CR2430 lets portable game consoles and their accessories run longer, ensuring reliable performance.
d. Computer Motherboards (CMOS Battery)
The CR2430 battery is used by some computer motherboards to retain system settings and a real-time clock while the computer is turned off.
e. Fitness trackers and wearables
As wearable technology starts to become a part of daily life, applications like smartwatches, heart-rate monitors, and fitness bands give rise to a strong need for small and powerful batteries like CR2430.
f. Automotive Devices
Car remotes, tire pressure sensors, and keyless entry systems use CR2430 batteries because of their reliability and long shelf life.
g. Medical Devices
Examples are specific medical instruments, including glucose meters, digital thermometers, and portable health monitors that use the CR2430 for continuous performance.
