Product characteristics & advantages

Why Evaluate the 103249 1800mAh High-Temperature LiPo Battery?

The 103249 model brings together a 6.66Wh calculated energy budget, 10 mm profile, 32 mm × 49 mm footprint, 1800mAh capacity and 50mΩ internal resistance. Its main design value is a medium-capacity, linear format for products that need longer operating intervals within a defined enclosure.

The 103249 lithium polymer battery is intended for OEM teams that need more operating energy than compact 230mAh or 500mAh formats can provide while retaining a manageable rectangular battery envelope. Its approximately 6.66Wh calculated energy supports early comparisons of reporting intervals, standby demand and active operating cycles. The 10 mm thickness and 32 mm × 49 mm plan area provide a clear mechanical reference for handheld, tracking and diagnostic enclosures. The listed 1C charge rate and 50mΩ internal resistance provide starting points for charger matching and voltage-drop discussions. Because temperature affects resistance, voltage stability, available capacity and charging behavior, contact ZERNE to confirm the final high-temperature configuration.

01 / ENERGY RESERVE

1800mAh for Longer Operating Intervals

The 1800mAh capacity and approximately 6.66Wh calculated energy help compare longer standby periods, reporting cycles and active operating demands in compact OEM devices.

02 / LINEAR FOOTPRINT

32 mm × 49 mm Pocket for Rectangular Layouts

The 32 mm × 49 mm plan area supports a linear battery-pocket approach. Review cable exit, retention, enclosure tolerance and service access around the pouch cell.

03 / PROFILE

10 mm Thickness for Defined Enclosure Depth

The 10 mm profile helps establish the available depth around the battery. Include cushioning, protection components, thermal paths and nearby heat sources in the assembly review.

04 / RESISTANCE

50mΩ for Load and Temperature Testing

The listed internal resistance supports an initial voltage-drop reference for the intended load. Test voltage stability across the target temperature range rather than treating the listed value as a guarantee.

05 / HIGH-TEMPERATURE VALIDATION

High-temperature Category with Model-Specific Confirmation

103249 is included in ZERNE's high-temperature lithium polymer battery range. Contact ZERNE to confirm operating temperature, charging limits, capacity retention and long-term performance for the required configuration.

Battery calculation

Check Capacity, Energy and Estimated Runtime

Use the prefilled 103249 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.

How to Use the Result

The 103249 values are prefilled: 3.7 V, 1800mAh and an approximate 1800mA 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 complete high-temperature sample testing, charger validation and final battery-specification review before production.

Integration guidance

Plan the 103249 LiPo Battery Around a Linear Pocket and Heat Exposure

The 103249 battery should be evaluated as part of the finished device: reserve the 32 mm × 49 mm footprint, allow for the 10 mm depth, match the 1C charge rate and test voltage stability across the intended temperature range.

01 / POCKET

Reserve the 32 mm × 49 mm Battery Area

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

02 / DEPTH

Map the 10 mm Profile Into the Enclosure

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

03 / CHARGING

Match the 1C Charge Rate Under the Intended Conditions

Set the charger and cell protection around the listed 1C rate, then confirm charging limits and temperature control for the finished product rather than assuming the category rating applies unchanged.

Applications & Solutions

Applications for the 103249 1800mAh High-Temperature LiPo Battery

The 103249 format is best evaluated against application-specific pocket geometry, energy demand and heat exposure rather than a generic device category. These three paths reflect its 10 mm × 32 mm × 49 mm envelope and 1800mAh capacity.
