Key Performance Advantages
1. Optimized 50mAh Capacity
While standard CR1225 cells often provide 48mAh, our CR1225T is chemically optimized to deliver a consistent 50mAh. This ensures longer maintenance cycles for your devices and reduced Total Cost of Ownership.
2. Stable Discharge Platform
Maintains a steady 3V voltage throughout 90% of its discharge cycle. This precision is critical for sensitive medical sensors and ICs that require constant voltage to maintain data accuracy.
3. Long Shelf Life
Utilizing high-purity electrolytes and advanced sealing technology, the CR1225T retains over 90% of its capacity even after a decade of storage, making it ideal for emergency backup systems.
4. Leak-Proof Industrial Design
The "T" series features an upgraded stainless steel casing and heat-resistant gasket, preventing electrolyte leakage even under fluctuating environmental pressures and vibration.
