n the architecture of enterprise hardware and connected IoT devices, a system is only as reliable as its baseline memory backup. The Omnergy CR1620 3V 70mAh Lithium Manganese Dioxide (LiMnO2) Coin Cell Battery represents the “Goldilocks zone” of micro-power geometry: an ideal balance of a compact footprint and high capacity.

With a standardized dimension of 16.0*2.0mm, this cell leverages a highly concentrated chemical payload to deliver a substantial 70mAh capacity. It serves as the unyielding data-security anchor for high-tier laptops, commercial payment networks, and precision automated instrumentation.

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.
