    HCB ER34615 Li-SOCI2 Battery precisely matches the new power supply requirements of IoT modules
    19 Sep, 2025
    HCB ER34615 Li-SOCI2 Battery precisely matches the new power supply requirements of IoT modules
    In the IoT era, the intensive application of "communication standard modules", "sensor integration modules", and "function expansion modules" has made the power consumption characteristics of devices diverse more - some require instantaneous high load support for data transmission, some need long-term low power consumption to maintain monitoring, and some rely on the parallel expansion of multiple batteries. Single balanced batteries are no longer able to meet the segmented demands. HCB Battery keenly identified and took the lead in making strategic plans. After launching the "Silver Bullet" series in 2020, it immediately initiated the research and development of lithium-ferrous batteries and capacitor combination batteries. In 2024, the "Direction" series passed the medium and long-term tests. We have developed the ER34615 (Silver Bullet), ER34615D (Direction), and ER34615DH (Direction-High Capacity) series of products, adhering to the concept of "tailoring to specific needs", to strengthen the power supply defense line for IoT devices.

    Key Differences: CR123A vs CR2 - How to Choose the Suitable Battery Solution?
    Lithium batteries power many modern electronic devices, ranging from security systems to industrial sensors. The most commonly used 3V primary lithium batteries include the CR123A and CR2. Both of these batteries are cylindrical lithium batteries, and both have an output voltage of 3V. However, they differ significantly in terms of size, capacity, and application scenarios. Understanding the differences between CR123A and CR2 batteries helps engineers, device manufacturers, and procurement teams select the right power source for their devices.
