Product Characteristics & Advantages
Micro-Compact Battery for Board-Side Placement: Why Evaluate the 401012C LiPo Battery?
The 401012C is the smallest-capacity reference in this group and is selected primarily for its compact envelope. Its 4.0mm profile and 450mΩ resistance mean that duty-cycle and peak-load review must be handled carefully.
The 401012C is the smallest-capacity reference in this group and is selected primarily for its compact envelope. Its 4.0mm profile and 450mΩ resistance mean that duty-cycle and peak-load review must be handled carefully. The calculated electrical references provide a structured starting point for charger, load and protection discussions, while the final battery remains a configurable OEM design.
10mm × 12mm for Micro Placement
The short plan area can fit beside a sensor, PCB edge or miniature control board when the device cavity is extremely limited.
4.0mm for Small Stack-Ups
Use the thickness to check the housing, cushioning, lead route and any compression risk in a tiny assembly.
0.11Wh for Very Low-Duty Devices
The calculated energy is a starting point for standby and occasional-use products, not a guarantee of runtime.
450mΩ for Conservative Peak-Load Review
The listed resistance calls for careful comparison with wake current, voltage margin, connector loss and cutoff behavior.
Approx. 0.6g Family Reference
The derived cell mass supports miniature product weight planning, while the finished battery will include connection and protection details.
Battery Calculation
Check 401012C Energy and Estimated Runtime
Use the prefilled 401012C 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. 15mA is the approximate standard-charge reference for 30mAh.

How to Use the Result
The 401012C reference values are prefilled: 3.7 V, 30mAh and a standard-charge reference of approximately 15mA. 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 401012C Battery at Board Level
For 401012C, the battery pocket may be smaller than the surrounding connection hardware. Review the 4.0mm thickness, 10mm × 12mm outline, lead route and 30mAh duty cycle together.
Protect the Small Pouch
Keep the 10mm × 12mm outline away from sharp PCB edges and housing ribs, and plan cushioning and retention before assembly.
Reserve Room for the Connection
In a micro enclosure, the lead exit and connector can occupy more space than the cell itself. Confirm the cable route and service access early.
Match 0.11Wh to the Duty Cycle
Use the calculated energy to compare standby and wake events, then validate usable capacity at the device cutoff.
Check Peak Load with Margin
The 450mΩ reference makes voltage-drop review important. Confirm current bursts, wires, connector and protection on the finished assembly.
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 401012C Micro LiPo Battery
The 401012C can be evaluated in miniature products where the physical battery pocket is extremely small and the operating duty cycle is correspondingly limited.
01Hearing Aids
The 4mm × 10mm × 12mm envelope is suited to an early hearing-aid feasibility review where every millimetre around the acoustic and charging assembly matters.
