The Engineering Edge: Why Specify the Omnergy CR1620?
1. Extended 70mAh Energy Density
By maximizing the internal vertical profile to 2.0mm, this cell provides up to 40% more capacity than its slimmer counterpart (the CR1616). For design engineers, this translates to an extra 3 to 4 years of field operation before routine maintenance cycles are required.
2. High-Performance Internal Kinetics (-20°C to 70°C)
Commercial and industrial environments expose electronics to diverse ambient climates. Our proprietary electrolyte formula maintains low internal resistance across extreme thermal fluctuations, ensuring a flat 3V discharge line whether deployed in an outdoor utility instrument or a tightly enclosed, heat-generating server chassis.
3. Anti-Corrosion Hermetic Seal & 10-Year Lifespan
Designed to safeguard high-value circuitry, our CR1620 features a heavy-duty stainless-steel casing paired with an innovative, leak-proof crimped insulation structure. With an annual self-discharge rate below 1%, it can remain passive for up to a decade while maintaining full data-retention readiness.
Core Application Ecosystems
Notebooks (NB) & Enterprise Computing
In modern computing infrastructure, maintaining the system BIOS configuration and Real-Time Clock (RTC) synchronization is crucial. The Omnergy CR1620 provides stable, long-term CMOS backup power to prevent data corruption during primary power disruptions or main battery swaps.

Frequently Asked Questions
Can I upgrade a device from a CR1616 to a CR1620 battery?
Both batteries share an identical diameter of 16.0mm and output a nominal 3.0V. However, the CR1620 is 2.0mm thick, while the CR1616 is 1.6mm thick. If your device's battery terminal slot has the vertical clearance to accommodate the extra 0.4mm, upgrading to the CR1620 is highly recommended, as it expands your capacity from 50mAh to 70mAh, increasing your device's operational lifespan by approximately 40%.
Why is the Omnergy CR1620 preferred for industrial POS terminals?
Industrial POS terminals require highly reliable, low-drain current to maintain volatile RAM encryption keys. Our CR1620 utilizes ultra-pure manganese dioxide and a specialized electrolyte that resists thermal degradation, guaranteeing the terminal never loses its encryption properties across years of continuous operation.
What is the shelf life of this factory-direct coin cell?
Thanks to our precision sealing technology and raw material purity, the internal self-discharge rate is kept under 2% annually when stored at standard room temperatures. This yields a highly dependable shelf life of 10 years.
