Integration & System Design Guidelines
Hot Lamination & Mechanical Integration: Compatible with low-temperature card hot-lamination processes (short-duration ≤ 130°C, ≤ 30 seconds). Tab ultrasonic spot welding or conductive epoxy bonding is recommended for PCB connection.
Operating Temperature Envelope: Standard charge operating range is 0°C to 45°C; continuous discharge operating range is -20°C to 60°C. Long-term storage target should be maintained at 3.80V–3.85V per cell in a dry, climate-controlled environment.
B2B Procurement & Lead Times: Available for wholesale OEM/ODM procurement with customized tab dimensions and flexible substrate layouts. UN38.3 test summaries, MSDS, and RoHS certification provided for export clearance.
Equipment Compatibility & Engineering Fit Check
Before deploying GEB 052026 3.7V 10mAh Ultra-Thin Flexible LiPo Battery Cell (0.5×20×26mm), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.7V / 10mAh power curves.
- Commercial designs requiring high volumetric energy density and predictable discharge curves.
- Projects requiring batch consistency with automated barcode impedance sorting.
⚠ Operational Constraints & Limits:
- Do not discharge below minimum cutoff voltage or charge beyond 4.2V.
- Maintain operational surface temperature within -20°C to +60°C discharge (0°C to +45°C charge).
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
