High-Capacity 3V 1350mAh Ultra-Thin Primary Lithium Manganese Dioxide LiMnO2 Pouch Battery CP303555
When engineering small-footprint IoT hardware, asset monitoring equipment, or ultra-low-profile smart electronics, the vertical space inside your enclosure is often your tightest constraint. Cylindrical cells take up too much height, and standard coin cells lack the milliamps required to sustain years of remote data transmission.
The CP303555 3V 1350mAh Primary Lithium Pouch Battery effectively eliminates this design bottleneck. By combining advanced soft-pack lithium manganese dioxide chemistry with automated precision manufacturing, this cell packs an impressive 1350mAh capacity into a flat profile that is just 3.0mm thick. Weighing a mere 10.5 grams, it delivers long-term autonomous power without compromising thin industrial or commercial device profiles.

Core Engineering & Performance Advantages
1. High Energy Density in a Flat Form Factor
Measuring just 3.0mm × 35.0mm × 55.0mm, the CP303555 can be mounted directly against product walls, inside structural internal panels, or behind PCBs. It delivers a high 1.35Ah energy reserve while maintaining a slim physical profile.
2. Decade-Grade Operational Shelf Life
Featuring a low annual self-discharge rate of 2% or less, this cell minimizes internal chemical degradation. This stable shelf life ensures that long-interval standby equipment, backup tracking tags, and warehouse inventories remain fully charged and operational over extended cycles.
3. Reliable Performance Across Thermal Extremes
Industrial deployment environments can be unpredictable. The CP303555 maintains a stable 3V discharge plateau across an operating temperature range of -40°C to +60°C, performing reliably in freezing cold-chain logistics networks as well as warm industrial environments.
4. Optimized Pulse Discharge Response
The internal architecture of our soft-pack primary cells is engineered to handle the high peak current pulses required by modern wireless chipsets (including NB-IoT, LoRa, BLE, Sigfox, and cellular LTE-M) without experiencing debilitating voltage drop.
