Product characteristics & advantages

Why Evaluate the 503033 500mAh High-Temperature LiPo Battery?

The 503033 model brings together a 1.85Wh calculated energy budget, 5.0 mm profile, 30 mm × 33 mm footprint, 500mAh capacity and 80mΩ internal resistance. Its main design value is a thin, moderate-capacity format for compact products that need more energy than a miniature cell.

The 503033 lithium polymer battery is intended for OEM teams that need to increase available energy without immediately moving to a much thicker battery format. Its approximately 1.85Wh calculated energy supports early comparisons of reporting intervals, standby demand and short active-load periods in compact products. The 5.0 mm thickness and 30 mm × 33 mm plan area provide a defined mechanical reference for slim enclosures and handheld electronics. The listed 1C charge rate and 80mΩ 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 BUDGET

500mAh for Longer Compact-Device Operation

The 500mAh capacity and approximately 1.85Wh calculated energy help compare standby demand, sensing intervals and active operating periods when a 230mAh-class format is not sufficient.

02 / THIN PROFILE

5.0 mm Thickness for Shallow Battery Pockets

The 5.0 mm profile helps define available enclosure depth. Include cushioning, protection components, thermal paths and nearby heat sources in the assembly review.

03 / FOOTPRINT

30 mm × 33 mm Plan Area for Compact Layouts

The 30 mm × 33 mm footprint gives designers a small rectangular battery reference. Review cable exit, retention, enclosure tolerance and service access around the pouch cell.

04 / RESISTANCE

80mΩ 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

503033 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 503033 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.

Runtime and charge time are estimates, not guaranteed product performance.

How to Use the Result

The 503033 values are prefilled: 3.7 V, 500mAh and an approximate 500mA 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 503033 LiPo Battery Around Thin Assembly and Heat Exposure

The 503033 battery should be evaluated as part of the finished device: reserve the 30 mm × 33 mm footprint, allow for the 5.0 mm depth, match the 1C charge rate and test voltage stability across the intended temperature range.

01 / POCKET

Reserve the 30 mm × 33 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

Protect the 5.0 mm Thin Profile

Check enclosure depth, compression risk, nearby components and thermal paths around the thin 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 503033 500mAh High-Temperature LiPo Battery

The 503033 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 5.0 mm × 30 mm × 33 mm envelope and 500mAh capacity.
