The 502030 is positioned around a thin package and a same-plan-area capacity comparison. Its 5.0mm thickness, 250mAh target and 100mΩ listing help design teams decide whether the device values lower depth or additional energy. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
20mm × 30mm for Compact Placement
The fixed outline can simplify comparison with the 582030 and preserve a concentrated battery bay near the PCB.
5.0mm for Shallow Integration
The thinner profile can create more room for board components, housing features or user-facing surfaces.
0.93Wh for a Defined Reserve
The calculated energy supports early runtime and recharge comparison for compact tracking, handheld and medical products.
100mΩ for Power-Path Planning
The listed resistance gives the electrical team a direct input for startup and voltage-drop questions.
Approx. 5.0g Family Reference
The derived mass supports a preliminary portable-device budget; final leads, protection and connector details remain configuration-specific.
Battery Calculation
Check 502030 Energy and Estimated Runtime
Use the prefilled 502030 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. 125mA is the approximate standard-charge reference for 250mAh.

How to Use the Result
The 502030 reference values are prefilled: 3.7 V, 250mAh and a standard-charge reference of approximately 125mA. 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
Compare the 502030 and 582030 in the Same Pocket
The 502030 is most useful when the product team can hold the 20mm × 30mm plan area constant and decide whether a 5.0mm, 250mAh configuration or a 5.8mm, 300mAh configuration better fits the product.
Keep the Plan Area Constant
Use the 20mm × 30mm outline to compare the two capacity configurations without redesigning the battery bay.
Protect the 5.0mm Depth Advantage
Reserve cushioning, retention and connection space so the thin cell is not compressed by the enclosure.
Set the Energy Tradeoff Explicitly
Approximately 0.93Wh is lower than the 582030 reference, so compare the capacity difference with runtime and recharge expectations.
Use the Resistance Listing Carefully
The 100mΩ value supports early voltage-drop screening, but the final current path must include the device load, wires, connector and protection.
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.
Applications & Solutions
Applications for the Thin 502030 LiPo Battery
