Product characteristics & advantages

Why Evaluate the 701238 280mAh Curved LiPo Battery?

The 701238 model brings together a 1.04Wh calculated energy budget, 7.0 mm profile, 12 mm × 38 mm footprint, 280mAh capacity and 120mΩ internal resistance. Its main design value is a balanced compact format for applications that need more energy than a micro cell without moving to a long battery strip.

The 701238 lithium polymer battery is intended for OEM teams that need a compact but useful energy reserve within a small enclosure. Its approximately 1.04Wh calculated energy supports early comparisons of sensor activity, intermittent wireless communication and short-to-moderate operating cycles. The 12 mm × 38 mm footprint keeps the battery pocket relatively compact, while the 7.0 mm thickness defines the enclosure-depth discussion. The listed 1C charge rate and 120mΩ internal resistance provide starting points for charger matching and voltage-drop evaluation. Confirm the final battery construction, connector, protection design and curved-device requirements.

01 / CAPACITY STEP

280mAh for Compact Runtime Planning

The 280mAh capacity and approximately 1.04Wh calculated energy provide more reserve than micro-capacity formats while keeping the product footprint suitable for smaller OEM devices.

02 / SHORT FORMAT

12 mm × 38 mm Area for Small Battery Pockets

The compact footprint supports early mechanical comparisons for small devices. Review retention, cable exit, enclosure tolerance and the available clearance around the cell.

03 / PROFILE

7.0 mm Thickness for a Defined Stack-Up

The 7.0 mm profile helps establish available depth around the pouch cell. Include cushioning, protection components and nearby parts in the enclosure review.

04 / LOAD REFERENCE

120mΩ for Voltage-Drop Evaluation

The listed internal resistance provides an initial reference for load and voltage stability discussions. Test the finished battery configuration under the intended operating conditions.

05 / CURVED INTEGRATION

Curved Battery Category for Shaped Product Concepts

701238 is included in ZERNE's curved lithium polymer battery range. Confirm the suitable construction, assembly method, protection and final device integration requirements.

How to Use the Result

The 701238 values are prefilled: 3.7 V, 280mAh and an approximate 280mA current derived from the listed 1C charge rate. Adjust the load power and efficiency to compare different operating scenarios.

  • Use the displayed energy reference for an initial runtime comparison.
  • Compare the estimate with measured device load and system efficiency.
  • Review charger settings and protection limits for the finished configuration.
  • Temperature, resistance growth and cutoff conditions affect actual performance.

Use the result as an initial estimate, then discuss sample testing, charger validation and the final battery specification with ZERNE.

Integration guidance

Plan the 701238 LiPo Battery Around a Compact Enclosure

The 701238 battery should be evaluated as part of the finished device: reserve the 12 mm × 38 mm footprint, allow for the 7.0 mm depth, match the 1C charge rate and review the construction requirements for the curved product design.

01 / POCKET

Reserve the 12 mm × 38 mm Battery Area

Allow space for the pouch cell, enclosure walls, cushioning, retention features, cable exit and service access around the compact battery footprint.

02 / DEPTH

Integrate the 7.0 mm Profile Into the Enclosure

Check enclosure depth, compression risk and adjacent components around the pouch cell before finalizing the mechanical stack-up.

03 / CURVED ASSEMBLY

Confirm the Final Curved-Device Construction

Discuss the required form factor, bend or contour conditions, protection, connector exit and assembly method with ZERNE before freezing the product enclosure.
