Jauch Introduces the New CR2450J – Optimized Coin Cell for Electronic Shelf Labels (ESL)

What Are electronic shelf labels (ESL)?

Electronic shelf labels, or ESLs, are digital price tags that automatically and centrally update pricing and product information. Their primary use is in retail environments, where price changes can be implemented in real time — without the need to manually replace paper labels.

Beyond pricing, ESL systems offer a wide range of additional functions:

• Advanced retail features such as promotional displays, inventory information, LED indicators for employee guidance, or QR/NFC interactions for customers
• Applications outside retail, including room and occupancy displays in conference areas, patient or room identification in healthcare, or warehouse and logistics processes where ESLs guide staff to specific shelf locations

To operate reliably across these varied applications, ESL systems require a long‑lasting and stable energy source — which is where the new CR2450J becomes essential.

CR2450J – Precise Power Supply for Digital Price Tags and Other Digital Displays

The new CR2450J is based on lithium manganese dioxide chemistry and provides a stable 3 V terminal voltage, a key requirement for E‑Paper displays. With a capacity of 620 mAh — approximately 10–20% more than standard cells of the same size — it is designed for multi‑year ESL operating cycles.

Additional Technical Features

• Ultra‑low self‑discharge (< 2% per year) for extended maintenance intervals
• Low internal resistance and high pulse‑current capability for reliable wireless burst currents (e.g., 2.4 GHz BLE/Zigbee), maintaining stability even at low temperatures
• Robust performance from –30 °C to +85 °C, making it suitable for refrigerated and deep‑freeze environments

With its combination of high energy density, stable voltage, and long service life, the CR2450J provides a reliable power supply for digital price tags as well as other IoT devices with low standby current and periodic radio‑frequency demands.
