2. Core Advantages of ER34615+1520 Composite Battery Pack
Compared with single lithium batteries and ordinary battery packs on the market, SERUI’s ER34615+1520 high-current primary lithium battery pack has multiple industrial-grade advantages in working performance, environmental adaptability, service life and safety, which is the core reason why it is widely used in smart water meters, IoT sensors, flow meters and PLC servo equipment.
2.1 Dual Complementary Design, Solve High-Current Pulse Pain Points
Most single LiSOCl2 Battery products have stable low-current discharge performance, but their instantaneous pulse discharge capacity is limited, which cannot meet the high-current instantaneous startup and signal transmission needs of smart meters and industrial control equipment. When the equipment collects data remotely, uploads signals and starts the servo system, it needs instantaneous large current support. Insufficient pulse current will lead to slow equipment response, data upload failure, and even system crash.
The Li-SOCl2 Battery with Super Capacitor 1520 adopts an optimized composite parallel design. The ER34615 main battery provides stable bottom voltage and long-term energy reserve, while the 1520 super capacitor instantly bursts out 2000mA high pulse current, which can quickly respond to equipment startup and signal transmission actions. This ER34615 With 1520 dual-power structure realizes the perfect cooperation of "slow energy storage and fast discharge", ensuring that the equipment has both ultra-long standby time and sensitive high-current response capability, which cannot be achieved by ordinary single batteries.
2.2 19Ah Large Capacity & Ultra-Low Self-Discharge, 10-Year Ultra-Long Service Life
Industrial IoT equipment and smart meters are usually installed in remote locations, wall interiors and equipment cabins, which are difficult to disassemble and replace batteries. Therefore, battery life is the key factor affecting equipment operation cycle. The main cell of the ER34615+1520 High Current Primary Lithium Battery Pack is high-purity LiSOCl2 Battery, with ultra-high energy density and extremely low self-discharge rate. The annual self-discharge rate is less than 1%, and the long-term storage life is up to 10 years.
The 19000mAh super-large capacity provides sufficient energy reserve for low-power equipment. Under the daily low-current standby and intermittent pulse working mode, the battery pack can continuously supply power for several years without replacement, which greatly reduces the after-sales maintenance pressure of smart water meters, flow meters and IoT monitoring equipment. For industrial users and property operation enterprises, it effectively reduces the overall operation cost and improves the stability of equipment operation.
2.3 Zero Voltage Hysteresis & Ultra-Wide Temperature Adaptation
Ordinary industrial lithium batteries are prone to voltage hysteresis after long-term low-current standby, resulting in insufficient instantaneous voltage when starting the equipment, which affects the normal collection and transmission of monitoring data. SERUI’sLi-SOCl2 Battery with Super Capacitor 1520 has excellent voltage response performance, zero hysteresis in the whole working process, stable and straight discharge voltage curve, and no sudden voltage drop.
At the same time, this ER34615 With 1520 battery pack breaks the temperature limitation of ordinary batteries. It can work stably in the ultra-wide temperature range of -40°C to +85°C. In low-temperature environments, it will not have insufficient discharge power; in high-temperature working conditions, the battery structure is stable, no bulging, no liquid leakage, and no thermal runaway. It is fully suitable for outdoor unattended monitoring, underground pipeline metering, factory high-temperature workshop equipment and other harsh working scenarios, ensuring all-weather stable operation of the equipment.
2.4 High Safety & Industrial-Grade Sealing Structure
