Why Choose the CR1620T (70mAh)?
1. Maximized 70mAh Energy Density
The CR1620T features an optimized internal structure that squeezes 70mAh into a 2.0mm thin profile. This extra capacity allows IoT devices and medical wearables to operate longer between maintenance cycles, reducing the total cost of ownership for end-users.
2. Advanced Leak-Proof Technology
Built with a reinforced stainless-steel shell and a high-performance sealing gasket, the CR1620T offers superior resistance to leakage and corrosion, even in fluctuating humidity and temperature environments.
3. Low Self-Discharge
Utilizing high-purity electrolytic manganese dioxide, this battery retains over 95% of its capacity after 5 years of storage. It is ideal for emergency backup and low-frequency "on-demand" devices.
4. Stable Discharge Platform
Maintains a consistent 3.0V output throughout the discharge life, ensuring that sensitive logic circuits and RF (Radio Frequency) modules function without signal dropouts.
