How to Use the Result
The 902551 values are prefilled: 3.7V and 1350mAh. 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 902551 Battery Around the 9.0mm × 25mm × 51mm Envelope
Reserve the stated battery pocket, allow for the 9.0mm thickness, review cable and connector access, and validate the charger, protection and finished load profile before production. Use the 25mm width and 51mm length to test placement beside the PCB. Review 9.0mm thickness and 60mΩ resistance with retention, peak load and temperature.
Reserve the 25mm × 51mm Battery Area
Allow space for the pouch cell, enclosure walls, cushioning, retention features, cable exit and service access around the listed footprint.
Check the 9.0mm 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 675mA standard-charge, 1350mA rapid-charge, 270mA standard-discharge and 1350mA maximum-discharge references for early review, then validate the finished battery assembly.
