The Engineering Edge: Why Specify the Omnergy CR1632?
1. Massive 120mAh Payload for Uninterrupted Lifecycles
By expanding the internal vertical volume to 3.2mm, this cell holds a significantly richer concentration of premium chemical active materials. For hardware design engineers, this means a massive drop in total cost of ownership (TCO) and field replacement costs, guaranteeing reliable background power for up to a decade.
2. High-Pulse Capability for IoT & Telemetry
Modern commercial hardware doesn't just store data; it transmits it. The internal architecture of our CR1632 is engineered for low internal resistance, allowing it to withstand sudden pulse current draws (e.g., RF mesh wake-ups, Bluetooth Low Energy bursts, or optical sensors) without suffering destabilizing voltage drops.
3. Industrial-Grade Thermal Survival (-20°C to 70°C)
From unventilated printing floors generating high ambient heat to outdoor security equipment exposed to freezing winter environments, the Omnergy CR1632 maintains stable internal chemical kinetics. The specialized organic electrolyte formula ensures structural integrity and zero cell swelling under high thermal strain.
Core Application Ecosystems
Notebooks (NB) & Motherboards
In enterprise laptops, servers, and embedded computers, maintaining the system BIOS configuration and Real-Time Clock (RTC) sync is crucial. The high capacity of the CR1632 ensures that system settings and network synchronization remain fully operational even during years of secondary power disconnection.
FinTech & Smart POS Terminals
Secure electronic payment terminals process sensitive encryption keys and compliance logs. Our CR1632 functions as the primary security backup cell, ensuring that anti-tamper mechanisms and volatile cryptographic memory stay fully energized to prevent hardware exploitation during main power shutoffs.

Frequently Asked Questions
Can I replace a CR1620 battery with a CR1632 battery?
Both batteries output a nominal 3.0V and share an identical diameter of 16.0mm. However, the CR1632 is 3.2mm thick, whereas the CR1620 is only 2.0mm thick. If your device's battery holder has the vertical physical clearance to accommodate the additional 1.2mm, upgrading to the CR1632 is an excellent engineering choice, as it expands your capacity from 70mAh to 120mAh, nearly doubling your device's service life.
Why is the Omnergy CR1632 preferred over standard consumer coin cells for POS terminals?
Industrial POS terminals require uninterrupted current over many years to preserve volatile RAM encryption keys. Our CR1632 uses ultra-pure manganese dioxide and a specialized electrolyte that resists thermal degradation, preventing the terminal from losing its cryptographic security data across years of continuous deployment.
What is the expected shelf life of this factory-direct battery?
Thanks to our precision sealing technology and raw material purity, the internal self-discharge rate is restricted to under 2% annually when stored at standard room temperatures. This yields a highly dependable shelf life of up to 10 years before deployment.
