Why Evaluate the 321447 Format?
A 3.2mm thickness gives the mechanical team a concrete depth boundary, while the 14mm × 47mm plan area follows a long internal channel in a compact product.
3.7 V Lithium Polymer Battery
The 321447 LiPo battery places a 180mAh rated capacity in a 3.2mm × 14mm × 47mm linear envelope. Its approximately 0.67Wh energy reference gives compact OEM products a clear starting point when length is available but cell depth is tightly limited.
Product Snapshot
The 321447 format is defined by its thin profile and 47mm length rather than by capacity alone. It can help a design team compare a narrow battery route, lead exit and 180mAh energy target before the housing is finalized.
A 3.2mm thickness gives the mechanical team a concrete depth boundary, while the 14mm × 47mm plan area follows a long internal channel in a compact product.
The 180mAh rating is a starting point for low-power duty cycles. Compare it with reporting frequency, active sessions and the available charging interval instead of treating capacity as a runtime guarantee.

Product Characteristics & Advantages
The 321447 is a thin linear reference for products where a long pocket is easier to provide than additional enclosure depth. The configuration keeps the selection discussion centered on depth, cable routing, energy planning and the listed 170mΩ resistance.
The 321447 is a thin linear reference for products where a long pocket is easier to provide than additional enclosure depth. The configuration keeps the selection discussion centered on depth, cable routing, energy planning and the listed 170mΩ resistance. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
The thin cell profile can preserve room for a board, display or housing wall, provided the finished assembly also has cushioning and retention clearance.
The long plan dimension can follow an enclosure edge or internal rail, with the lead exit placed to protect the board-side connection path.
The calculated energy supports early comparison of standby time, periodic communication and short active sessions.
The listed resistance gives the electrical team a reference point for startup behavior and voltage-drop discussion; the finished assembly still requires validation.
The calculated mass is useful in a preliminary portable-device budget, while final weight depends on leads, protection and connector details.
Battery Calculation
Use the prefilled 321447 values or enter your own load assumptions for a quick energy and runtime estimate.
Energy is calculated from nominal voltage and capacity. Runtime uses the entered load power and an adjustable efficiency assumption.
Approx. 90mA is the approximate standard-charge reference for 180mAh.
The 321447 reference values are prefilled: 3.7 V, 180mAh and a standard-charge reference of approximately 90mA. Adjust the load power and efficiency to compare operating scenarios; the calculator does not infer safe limits from capacity alone.
Use the result for early comparison, then confirm the charger, protection, connector and final battery specification through sample testing.
Integration Guidance
The 321447 should be checked as a long, shallow battery assembly. Review the 3.2mm depth, 14mm width, 47mm length and lead path together with the 180mAh operating target.
Reserve more than the 3.2mm cell dimension for cushioning, tolerance and the finished protection arrangement; avoid compression from housing ribs.
A 47mm channel may allow the cell to sit beside the PCB, but confirm end retention and cable bend radius before the enclosure is released.
Use approximately 0.67Wh to compare reporting intervals and active load. Cutoff voltage, temperature and system losses determine the usable window.
The listed 170mΩ value can guide early voltage-drop questions, but peak current, connector resistance and final protection must be checked on the complete battery.
Applications & Solutions
The 321447 format can be evaluated in compact products that provide a narrow, elongated battery route and need a modest energy reserve without adding much depth.
01The 3.2mm profile and 47mm length are a useful starting point for GPS card products that need a slim, elongated battery pocket and scheduled location updates.

The 321447 reference is specified as 3.2mm × 14mm × 47mm in thickness × width × length order. Allow additional room for cushioning, retention, leads, connector and protection.
The rated capacity is 180mAh at a nominal voltage of 3.7 V. The calculated energy is approximately 0.67Wh before cutoff, load, temperature, resistance, protection and system losses.
Using the 3.7 V LiPo family weight reference, the 180mAh configuration is approximately 3.6g. Finished weight depends on leads, connector, protection and assembly details.
The calculated current references are approximately 90mA standard charge, 180mA rapid charge, 36mA standard discharge and 180mA maximum discharge. Confirm the final safe limits for the completed battery.
The 321447 reference is only 3.2mm thick and 47mm long, so it is most useful when the device offers a narrow linear channel but limited depth.
ZERNE can review connector, cable, protection and assembly requirements around the 321447 envelope as part of a custom OEM discussion.
