Introduction
In scenarios such as real-time smoke alarm triggering, instantaneous response of car alarms, long-term metering of water and gas meters, and continuous communication of IoT devices, batteries, as the "power hub", must overcome three key technical bottlenecks: tolerance to extreme environments (wide temperature range of -40℃ to 85℃, protection against moisture and dust), long-term performance stability (low self-discharge, no voltage fluctuations), and dynamic adaptation to scenarios (balancing high-current pulses and long battery life). Wuhan HCB Battery Co., Ltd., a leader in the field of primary lithium batteries, has launched the fully sealed CR17450 battery and semi-sealed CR17450H battery. With the technical innovation of the lithium-manganese dioxide system, it has become the benchmark power solution for the above scenarios and redefined the performance standards of industrial-grade batteries.
Product Matrix Positioning: Precise Scenario Targeting of Fully Sealed vs. Semi-Sealed Designs
Both HCB CR17450 and CR17450H belong to the 3.0V lithium-manganese dioxide system, categorized as 4/5A size power-type batteries. However, their sealing characteristics and performance boundaries create differentiated positioning, covering all scenario needs from basic to complex:
CR17450 Fully Sealed Battery: Focused on "high-frequency response + complex environment" scenarios. With an operating temperature range of -40℃ to +85℃ and a maximum continuous discharge current of 1500mA, it is suitable for medical devices, GPS, radio communication, CNC machine tools, underwater equipment, and other terminals requiring high response speed and strong environmental adaptability.
CR17450H Semi-Sealed Battery: Targeting "conventional scenarios + extended needs". Boasting an operating temperature range of -40℃ to +70℃, a high capacity of 2400mAh, and a more flexible sealing design, it delivers long service life and is ideal for smoke detectors, car alarms, water/gas meters, and other terminals prioritizing capacity and multi-scenario compatibility.
Together, these two products form a product matrix that "covers all basic scenarios and penetrates deep into complex scenarios", providing tiered power options for industrial intelligent terminals.
Core Technological Breakthroughs: Four Innovative Dimensions Supporting High Performance
The outstanding performance of CR17450 and CR17450H stems from HCB Battery's in-depth research and development in three key areas: material science, structural design, and process optimization. Four core technologies together form the product's competitive barrier, making it stand out among similar batteries.
High Specific Energy Material System: Breaking the Limits of Energy Density
CR17450 and CR17450H adopt a highly active lithium-manganese dioxide (Li-MnO₂) chemical system. Through innovations in cathode materials and separators, they enhance electrode reaction activity and electron conduction efficiency, achieving an energy density of 830Wh/L—far exceeding the average level of traditional primary lithium batteries.
High energy density means CR17450 and CR17450H can store more energy in the same volume. For example, in the standard 4/5A size (only 80% the volume of a regular AA battery), they deliver 1.5 times the energy output of traditional batteries, perfectly adapting to miniaturized, highly integrated modern electronic devices.
Optimized Structural Design: Leapfrog Improvement in Discharge Capacity
The battery cells feature a wound design, enabling CR17450 and CR17450H to achieve dual breakthroughs in "high-current discharge" and "low internal resistance." This design increases the electrode reaction area and reduces ion transmission resistance, resulting in a maximum continuous discharge current of 1500mA and a peak pulse discharge current of 3000mA.
This characteristic allows the batteries to easily power devices requiring instant high power, such as RFID reader signal transmission and high-frequency communication of wireless modules. Meanwhile, the optimized structure minimizes voltage fluctuations during discharge, achieving "no voltage lag" and ensuring stable device operation.
Wide Temperature Range Adaptation Technology: Reliable Operation in Extreme Environments
Tailored for outdoor and industrial complex environments, CR17450 and CR17450H achieve an ultra-wide operating temperature range through improved electrolyte formulations and upgraded shell materials. The power-type fully sealed battery operates stably between -40℃ and +85℃, while the power-type semi-sealed version works reliably from -40℃ to +70℃, covering most application scenarios in conventional use.
In low-temperature environments, the special electrolyte maintains excellent ionic conductivity to prevent sudden capacity drops. In high temperatures, heat-resistant shell materials and advanced sealing technology prevent electrolyte leakage, ensuring consistent performance.
Low Self-Discharge Control Technology: Core Guarantee for Ultra-Long Lifespan
CR17450 and CR17450H utilize high-purity electrode materials and precision sealing processes, controlling the annual self-discharge rate to less than 1% when stored at +25℃. This means the batteries require no frequent replacement after delivery; even after long-term storage (theoretically over 10 years), they retain over 80% of their initial capacity.
For "maintenance-free" devices such as buried smart water meters and remote monitoring terminals, this low self-discharge feature significantly reduces maintenance costs, extends device lifecycles, and creates greater economic value for users.
