Battery calculation
Check 103040 Energy and Estimated Runtime
Use the prefilled 103040 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 is an estimate, not guaranteed product performance.

How to Use the Result
The 103040 values are prefilled: 3.7V and 1200mAh. Adjust the load power and efficiency to compare different operating scenarios.
- Energy is estimated from nominal voltage and capacity
- Runtime estimate = energy × efficiency ÷ load power
- Actual runtime depends on load profile, cutoff, temperature and system losses
- Use sample testing to validate the final battery and device combination
Use the result as an initial estimate, then discuss charger validation and the final battery specification with ZERNE.
Integration guidance
Plan the 103040 Battery Around the 10mm × 30mm × 40mm Envelope
Reserve the stated battery pocket, allow for the 10mm thickness, review cable and connector access, and validate the charger, protection and finished load profile before production. Check the 30mm width against the PCB edge and the 40mm length against the connector exit; review cushioning and housing clearance around the full 10mm stack.
Reserve the 30mm × 40mm Battery Area
Allow space for the pouch cell, enclosure walls, cushioning, retention features, cable exit and service access around the listed footprint.
Check the 10mm Profile
Review compression risk, enclosure tolerances and adjacent components around the battery before finalizing the mechanical design.
Confirm Electrical and Protection Requirements
Use the calculated 600mA standard-charge, 1200mA rapid-charge, 240mA standard-discharge and 1200mA maximum-discharge references for early review, then validate the finished battery assembly.
