Product Characteristics & Advantages
Small Footprint with Low Listed Resistance: Why Evaluate the 401224 LiPo Battery?
The 401224 is a compact 80mAh reference with a notably low listed 85mΩ resistance. Its page angle connects the small pocket with voltage-drop review rather than presenting the capacity as a standalone runtime promise.
The 401224 is a compact 80mAh reference with a notably low listed 85mΩ resistance. Its page angle connects the small pocket with voltage-drop review rather than presenting the capacity as a standalone runtime promise. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.

Battery Calculation
Check 401224 Energy and Estimated Runtime
Use the prefilled 401224 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. 40mA is the approximate standard-charge reference for 80mAh.

How to Use the Result
The 401224 reference values are prefilled: 3.7 V, 80mAh and a standard-charge reference of approximately 40mA. 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
Integrate the 401224 Battery Around Voltage Margin
The 401224 combines a compact pocket with an 85mΩ resistance reference. Review the 4.0mm × 12mm × 24mm envelope, load peaks, cable path and 80mAh energy target together.
Keep the Short Outline Accessible
Reserve the 12mm × 24mm area and avoid placing a connector or housing rib where it creates pressure on the pouch.
Use the Resistance as a Screening Input
Compare 85mΩ with the device peak current, cable length, connector and cutoff voltage when checking startup margin.
Match 0.30Wh with Actual Use
Use the calculated energy to compare standby and active sessions; usable energy changes with load and system losses.
Confirm the Final Charging Path
The capacity-based currents are planning references. Validate charger, protection and thermal behavior on the complete configuration.
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.
