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.
Professional Applications
The CR1620T is the preferred power solution for:
• Smart Wearables: Ultra-thin health trackers, digital watches, and fitness monitors.
• Automotive: Slim-profile Smart Key Fobs and Remote Keyless Entry systems.
