BR3032 3V 500mAh Lithium Coin Cell: Wide Architecture, Deep Power Reserves, Flat Profile
When your hardware demands heavy-duty standby energy but faces tight vertical clearance, standard stacked or thick button cells will not fit the enclosure. The Omnergy BR3032 3V Lithium Carbon Monofluoride (Li-CFx) Coin Cell resolves this engineering bottleneck.
By spreading a robust 500mAh capacity across an expanded 30.0mm horizontal footprint, the BR3032 maintains a slim line of just 3.2mm. It is the ultimate "install-and-forget" standby power solution for low-profile enterprise hardware, sleek retail electronics, and ruggedized security systems that refuse to compromise on device lifespan.

Core Advantages: Engineering the Horizontal Space
1. Geometric Optimization (Φ30.0 × 3.2mm)
Why build taller when you can build smarter? The BR3032 leverages a wide surface area to pack double the capacity of a standard 2032 cell without adding a single millimeter of height. It is tailored perfectly for high-density server blades, compact mobile terminal payment systems, and flat sensor housings.
2. Flawless Extreme Temperature Performance (-40°C to +85°C)
Industrial computing and outdoor telemetry must endure severe environments. Our advanced Li-CFx chemical structure ensures a completely stable, leak-free, and fade-free voltage output whether operating in freezing sub-zero outdoor security grids at -40°C or baking inside heavily taxed enterprise server racks at +85°C.
3. Decade-Defying Standby Lifespan (<2% Annual Self-Discharge)
Frequent field maintenance drains profitability. Rigorously engineered for long-term B2B infrastructure deployment, the Omnergy BR3032 boasts a self-discharge rate of less than 2% per year. Your system configuration, transaction logs, and Real-Time Clocks (RTC) stay protected in standby mode for more than 10 years.
Target Applications: Powering Slimline B2B Ecosystems
The unique 500mAh profile of the BR3032 makes it the premier choice for sleek, mission-critical electronics:
Enterprise Servers & 1U Datacenter Blades: Fits seamlessly into ultra-thin server chassis to provide high-capacity CMOS and RTC backup, ensuring internal clocks and system logs survive prolonged power loss.
Point of Sale (POS) Terminals & ATMs: Safely secures offline transactional data, security logs, and financial encryption keys in low-profile smart registers and payment gateways.
Commercial Security & Smart Access Control: Delivers relentless, years-long power for slim electronic door locks, flat biometric scanners, and remote outdoor perimeter sensors.
Industrial Controls & Medical Tech: Acts as the ultra-reliable memory backup infrastructure for Programmable Logic Controllers (PLCs) and medical monitoring systems that require high energy density within a flat design.
Engineering Insight: Spreading the Power Footprint
Why choose a 30mm diameter cell over a thicker 24.5mm variant?
The decision comes down to Z-Axis Constraints vs. Energy Demands. When a hardware design requires a substantial 500mAh reserve to guarantee a 10+ year lifespan, engineers often look to thick cells like the BR2450 (5.0mm) or BR2354 (5.4mm). However, if your PCB sits in a slim enclosure where every fraction of a millimeter in height counts, the BR3032 allows you to capture that exact same 500mAh capacity while cutting vertical thickness down to a mere 3.2mm.
Additionally, shifting from consumer CR (Lithium Manganese Dioxide) chemistry to Omnergy’s industrial BR-series (Li-CFx) provides a perfectly flat 3.0V discharge profile. This eliminates the gradual voltage decay typical of CR cells, ensuring sensitive microprocessors receive continuous, unfluctuating voltage until the cell is entirely spent, even under continuous 85°C operational heat.
