We Power Your Technology!
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 Li-SOCI2 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.
Panoramic comparison of core parameters: Understand the adaptation logic at a glance
The ER34615 series batteries from HCB are all based on a base capacity of 19000mAh, a nominal voltage of 3.6V, and a wide operating temperature range of -55℃ to 85℃. Relying on the multi-cathode formula technology, they form precise stratification in terms of loss control, discharge performance and lifespan, and are suitable for different module application scenarios.
Capacity loss: The percentage of capacity loss of the battery when placed upright and horizontally.
Usable Capacity under Low-Rate Discharge: The usable capacity obtained under room temperature through a 4mA cross-current discharge.
Expected Operational Life: The recommended service life under certain usage conditions is provided for preliminary evaluation only. The specific service life must be calculated based on specific power consumption conditions. This table is not to be used as a warranty basis.
Delving into Differences: How Does the Technical Core Determine Application Segmentation?
Behind the parameter differences in the above form HCB's profound technical optimization for various application scenarios. Understanding these differences is the key to making the right choice.
The name "Direction" comes from its perfect compatibility with UPC (Battery Capacitor) - just like a compass magnetic spoon and a bronze plate complementing each other, achieving an efficiency greater than the addition of "battery + capacitor". It is specifically designed for devices with large working currents, communication functions, and high communication frequencies.
(1) ER34615D (Direction) : Expert in pulse applications, with a 15-year long lifespan commitment
Technical advantages: The unique patented positive electrode and current collector structure ensures high capacity at low current. There is no capacity loss when placed horizontally or vertically. Below 25℃, the average annual self-discharge rate is as low as less than 0.7%, making it safe and reliable. The battery pack can reach the T4 explosion-proof grade. When combined with the UPC series, the 15-year ultra-long design life and no orientation installation restrictions significantly reduce the maintenance cost and usage flexibility throughout the entire life cycle.
Scenarios: Smart cities, smart fire protection, smart parking lots, industrial sensor networks and other communication module devices that require frequent and high-intensity pulse currents.
(2) ER34615DH (Direction-High Capacity) : The king of ultra-long-term maintenance-free operation, with an ultra-long lifespan of 20 years
Technical advantages: Based on maintaining all the advantages of the "Direction" series (no loss, high pulse, ultra-low self-discharge), it improves the utilization rate of active materials by optimizing the internal structure of the carbon cathode carrier. Under low-rate discharge, it can release 5.9% more available capacity than the standard version, meeting the IEC60086-4, EN60079-11, and T4 explosion-proof standards.
Scenarios: Targeted at all high-end applications with extreme requirements for lifespan and reliability, especially those scenarios that are completely impossible or extremely difficult to maintain after deployment. Such as underground pipeline monitoring systems, container trackers for ocean shipping, deep soil monitoring stations for smart agriculture, remote monitoring for oil fields, and monitoring devices for key nodes of State Grid, etc.
RFQ High-frequency Questions: No Blind Spots for Procurement Decisions
1. What are the nominal voltage and rated capacity of the ER34615 series batteries?
The nominal voltage of the HCB ER34615 series battery is 3.6V, which is a stable high working voltage platform. With a rated capacity of up to 19000mAh (under standard load conditions), it is one of the products with the highest energy density among disposable lithium batteries at present, capable of providing over ten years of ultra-long battery life for IoT devices.
2. Which UPC is usually recommended for the ER34615 Direction series?
Depending on the usage scenario, the ER34615+UPC1520 and ER34615+UPC1550 combinations are usually recommended.
3. Can product certification cover the global demand for IoT module devices?
All HCB batteries have passed UN38.3 transportation certification and RoHS environmental protection certification. The Direction series has also obtained CE certification, which can be directly adapted to module equipment in the EU and North America regions. For the gas meter module scenario, ATEX explosion-proof certification can also be customized.
4. Can the HCB ER34615 directly replace the same model of other brands?
Definitely.The HCB ER34615 series is compatible and directly replaceable with the same models of other brands in terms of size, voltage and capacity. The advantages of HCB lie in offering a diverse product range (D/DH), competitive cost performance and faster technical service support.
5. How to apply for samples for testing? Does it support customized requirements?
