CR1620T 3V 70mAh High-Density Lithium Manganese Dioxide (Li-MnO2) Battery Slim Profile.

The CR1620T is a precision-engineered 3V lithium coin cell designed for applications where space is at a premium but power demand is high. With an upgraded 70mAh nominal capacity, this “T” series variant provides a significantly longer service life than standard CR1620 batteries. It is the ideal choice for OEM/ODM manufacturers requiring stable power for miniaturized high-tech electronics.

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.
