Product Characteristics & Advantages
Thin Broad-Pocket Reference for Mobile Tools: Why Evaluate the 503638 LiPo Battery?
The 503638 selection angle is thinness across a broad pocket, not maximum capacity. The 5mm profile can help when height is constrained, while the 36mm × 38mm area needs clear retention and assembly planning.
The 503638 selection angle is thinness across a broad pocket, not maximum capacity. The 5mm profile can help when height is constrained, while the 36mm × 38mm area needs clear retention and assembly planning. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
2.74Wh for a Defined Operating Target
Use the calculated energy to compare the product load, standby interval and desired recharge schedule.
5mm × 36mm × 38mm for Enclosure Planning
Review the cell envelope with cushioning, protection, retention and cable access before releasing the battery bay.
Capacity-Derived Current References
The table gives early charger and load inputs; final electrical limits depend on the approved battery assembly.
80mΩ for Current-Path Screening
Use the supplied value as an early reference and validate the complete assembly under the intended load.
Qualified Low-Temperature Evaluation
Confirm usable capacity, charging limits and cold-start behavior at the actual required operating condition.
Battery Calculation
Check 503638 Energy and Estimated Runtime
Use the prefilled 503638 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. 370mA is the approximate standard-charge reference for 740mAh.

How to Use the Result
The 503638 reference values are prefilled: 3.7 V, 740mAh and a standard-charge reference of approximately 370mA. 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
Keep the Thin Battery Clear of the Board and Housing
Reserve the 36mm × 38mm area, protect the 5mm profile, and keep connector and lead routing outside the active pouch boundary.
Shallow Bay
Use the 5mm value as a cell reference while leaving room for the full finished assembly and tolerances.
Board Adjacency
A broad pocket can simplify energy placement but may compete with the PCB, display or grip structure.
Temperature Testing
Low-temperature validation should include the charger, protection circuit, connector and actual device load.
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.
