3.7 V Lithium Polymer Battery

3.7 V 180mAh Lithium Polymer Battery 321447

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

A 3.2mm Profile for Long, Narrow Battery Channels

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.

Use the Capacity with the Channel Design

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

Ultra-Thin Long-Channel Integration: Why Evaluate the 321447 LiPo Battery?

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.

01 / PROFILE

3.2mm for Shallow Enclosure Stacks

The thin cell profile can preserve room for a board, display or housing wall, provided the finished assembly also has cushioning and retention clearance.

02 / LENGTH

47mm for a Linear Pocket

The long plan dimension can follow an enclosure edge or internal rail, with the lead exit placed to protect the board-side connection path.

03 / ENERGY

0.67Wh for Low-Power Planning

The calculated energy supports early comparison of standby time, periodic communication and short active sessions.

04 / RESISTANCE

170mΩ for Voltage-Drop Review

The listed resistance gives the electrical team a reference point for startup behavior and voltage-drop discussion; the finished assembly still requires validation.

05 / WEIGHT

Approx. 3.6g Family Reference

The calculated mass is useful in a preliminary portable-device budget, while final weight depends on leads, protection and connector details.

Battery Calculation

Check 321447 Energy and Estimated Runtime

Use the prefilled 321447 values or enter your own load assumptions for a quick energy and runtime estimate.

LiPo Battery Capacity Calculator

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.

How to Use the Result

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.

  • Energy = voltage × capacity ÷ 1000
  • Runtime estimate = energy × efficiency ÷ load power
  • Ideal charge time = capacity ÷ entered charge current
  • Actual runtime depends on load profile, temperature, cutoff and system losses

Use the result for early comparison, then confirm the charger, protection, connector and final battery specification through sample testing.

Integration Guidance

Integrate the 321447 Battery Along a 47mm Pocket

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.

Protect the Shallow Stack-Up

Reserve more than the 3.2mm cell dimension for cushioning, tolerance and the finished protection arrangement; avoid compression from housing ribs.

Use the Length to Free Board Space

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.

Relate Energy to the Duty Cycle

Use approximately 0.67Wh to compare reporting intervals and active load. Cutoff voltage, temperature and system losses determine the usable window.

Review Resistance Under Load

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.

The stated dimensions and calculated values are reference inputs for design planning. Confirm the finished battery drawing, tolerance, protection, connector and test conditions before production release.
