Product Details
The GEB ICR14650 3.7V 1200mAh Cylindrical Li-ion Battery Cell (14×65mm) is a Grade-A slim cylindrical Lithium-ion cell delivering 3.7V nominal operating voltage and 1,200mAh rated capacity (4.44Wh total energy). Engineered in a slender 14mm diameter steel canister with integrated CID/PTC pressure-relief mechanisms, this 14650 cell offers a continuous discharge capability of 1.0C–1.5C (1.2A–1.8A) with low internal resistance (≤ 35–50 mΩ) and a calibrated unit weight of approximately 28.0g. Specifically tailored for slender cylindrical cavities such as sonic electric toothbrushes, facial beauty devices, LED inspection penlights, and handheld medical instruments, engineers should verify battery compartment dimensions (Ø 14.2mm × H 65.0mm) and ensure proper insulation sleeves during assembly.
Product Overview
The GEB ICR14650 3.7V 1200mAh Cylindrical Li-ion Battery Cell (14×65mm) provides significantly higher energy capacity than standard 14500 (AA-size) cells by utilizing an extended 65mm body height while maintaining an ergonomic 14mm slim diameter. Delivering 3.7V nominal voltage and 1200mAh rated capacity, it features physical dimensions of Ø 14.2 ± 0.2 mm × H 65.0 ± 0.3 mm and a calibrated lightweight mass of Approx. 28.0g ± 1.5g. It is widely adopted across OEM personal grooming devices (sonic toothbrushes, electric shavers, skin massagers), tactical LED penlights, wireless presentation pointers, and handheld diagnostic meters.

Equipment Compatibility & Engineering Fit Check
Before deploying GEB ICR14650 3.7V 1200mAh Cylindrical Li-ion Battery Cell (14×65mm), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.7V / 1200mAh 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.
