Power Glory CR2450: A High-Capacity Button Cell Solution—From Electronic Price Tags to the Internet of Everything
Power Glory CR2450: A High-Capacity Button Cell Solution—From Electronic Price Tags to the Internet of Everything
Walk into a new-retail supermarket, and you’ll see that paper price tags on the shelves are being replaced by electronic displays. These electronic shelf labels (ESLs) can be updated remotely in real time, display promotional information, and track inventory status; each label requires an independent power source and operates at low power consumption for 5 to 8 years.
In this application, the CR2450 button cell battery, with its high capacity and high pulse discharge capability, is becoming a key power solution for ESLs and a wider range of IoT devices.
The Physical Characteristics and Capacity Advantages of the CR2450
The meaning behind “CR2450” is actually quite simple: “CR” stands for the “lithium-manganese dioxide” chemical system, “24” refers to a diameter of 24.5 mm, and “50” refers to a thickness of 5.0 mm.
Compared to the most common CR2032 (Φ20.0 × 3.2 mm), the CR2450 is approximately 85% larger in volume, and its nominal capacity has nearly tripled.
Comparison of Key Specifications for the Power Glory CR2450 Series:
Parameter | CR2450(Standard Type) | CR2450PH(High-Capacity Type) | CR2450HT(TPMS Wide-Temp) | CR2450D(Low-Temp Type) |
Nominal Voltage | 3V | 3V | 3V | 3V |
Nominal Capacity | 600mAh | 620mAh | 550mAh | 600mAh |
Standard Current | 0.4mA | 0.4mA | 0.4mA | 0.4mA |
Max. Continuous Current | 7mA | 8mA | 7mA | 7mA |
Max. Pulse Current | 25mA | 28mA | 20mA | 25mA |
Operating Temperature | -20°C to +70°C | -20°C to +70°C | -40°C to +125°C | -55°C to +60°C |
Pulse discharge capability is a key metric that distinguishes the CR2450 from the CR2032. The Power Glory CR2450PH delivers a maximum pulse current of 28 mA, nearly twice that of a standard CR2032 (approximately 10–15 mA). For IoT operating modes that involve “remaining in sleep standby mode during normal operation and instantly waking up to transmit upon triggering,” the pulse current directly determines the device’s response sensitivity and RF transmission reliability—and this is one of the core reasons why the CR2450 series excels in applications such as ESL, BLE beacons, and TPMS.
Electronic Shelf Labels: Large-Scale Validation of the CR2450
A large supermarket can deploy tens of thousands of ESLs, each of which requires an independent power supply and must operate at low power consumption for 5 to 8 years. The CR2450’s continuous power output perfectly matches the ESL’s operating mode of “sleep mode during normal operation and instant wake-up during refresh.” The ultra-low annual self-discharge rate (no more than 2%) ensures virtually maintenance-free operation after deployment, significantly reducing operational costs associated with manual battery replacement.
For retail chains, the stable operation of hundreds of stores and millions of price tags across a single city relies on the consistent quality of this battery—a standard guaranteed by Power Glory’s fully automated production lines and vision inspection systems, which enable a monthly production capacity of 66 million units.
More Than Just ESL—The CR2450’s Wide-Ranging Applications in the IoT Field
The CR2450’s applications extend far beyond retail shelves.
Smart Home: Low-power nodes such as temperature and humidity sensors, motion sensors, and door/window magnetic sensors can operate maintenance-free for 5 to 10 years on a single CR2450 battery.
Asset Tracking and Location: The CR2450 provides stable power for BLE beacons and LoRa location tags. Its 25mA/28mA pulse current drives periodic burst transmissions from RF modules, delivering a battery life of 3 to 5 years under standard transmission intervals.
Smart Meters: Remote transmission modules for water and gas meters use the CR2450 to meet peak current demands during communication.
In-Vehicle TPMS: Tire pressure sensors utilize the CR2450HT wide-temperature variant, which operates reliably in environments ranging from -40°C to +125°C.
With Power Glory’s CR-HT high-temperature series (125°C) and CR-D low-temperature series (-55°C), as well as IATF 16949 automotive-grade certification, the CR2450 in a leaded package addresses diverse IoT power supply needs—ranging from smart home applications to industrial sensing, and from asset tracking to in-vehicle safety.
