Key Performance Advantages
1. Medical-Grade Reliability & Voltage Stability
When deployed in critical health-monitoring hardware, voltage drops are not an option. Our CR1025 utilizes an advanced LiMnO2 chemical composition that maintains a flat 3.0V discharge curve throughout most of its operational lifespan, ensuring precise data transmission and sensor accuracy.
2. Extreme Thermal Resilience (-20°C to 70°C)
From outdoor industrial asset trackers to cold-chain medical transport sensors, this battery is built to survive harsh environments. The optimized organic electrolyte formula prevents crystallization at freezing temperatures and resists degradation in high-heat scenarios.
3. Decaded-Long Shelf Life (Low Self-Discharge)
Featuring a high-integrity leakage-proof seal and premium raw materials, our CR1025 boasts a self-discharge rate of less than 2% per year. This makes it an ideal choice for emergency backup systems and products that sit in distribution channels for extended periods.
Primary Applications
Medical Devices & Wearables
The ultra-lightweight and compact footprint makes the CR1025 the go-to power source for minimally invasive medical hardware, including:
