Product Overview
The GEB CR2354 3.0V 480mAh Primary Li-MnO2 Button Cell Battery with Solder Tabs is an industrial-grade, non-rechargeable lithium manganese dioxide coin cell engineered for ultra-long service life in low-power electronics and critical backup applications. Featuring a high nominal energy capacity of 480mAh (1.44Wh) and an ultra-low self-discharge rate of less than 1% per year at 20°C, this cell provides stable 3.0V voltage plateau output across a wide ambient temperature range from -30°C to +70°C. Encased in a hermetically sealed stainless steel housing measuring Ø 23.0 × 5.4 mm with pre-welded nickel-plated solder pins, it is widely utilized for smart water/gas metering, real-time clock (RTC) data retention, automotive TPMS systems, and medical IoT nodes. Prior to PCB layout, verify solder pin pinout spacing and polarity orientation.

Equipment Compatibility & Engineering Fit Check
Before deploying GEB CR2354 3.0V 480mAh Primary Li-MnO2 Button Cell Battery with Solder Tabs, verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Utility meters, IoT telemetry nodes, and remote tracking devices requiring 3.6V long-life power.
- Sub-zero or high-temperature deployments (-55°C to +85°C) where rechargeable chemistries fail.
- Autonomous sensors demanding microamp standby combined with scheduled RF pulse bursts.
⚠ Operational Constraints & Limits:
- Do not recharge: Connecting to external chargers risks thermal runaway or internal pressure venting.
- Avoid dead-shorting terminals during installation; maintain cell insulation integrity.
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
