Product Details
The GEB 14500 3.7V 800mAh Cylindrical Lithium-ion Battery Cell (AA Size) is a compact rechargeable lithium-ion cell sharing standard AA dimensions (Ø 14.5 × 50.5 mm) while delivering 3.7V nominal output—over 2.4 times the operating voltage of standard 1.5V alkaline/NiMH batteries. Weighing approximately 20g (±1g), it delivers 800mAh rated capacity (2.96Wh), 1C–2C continuous discharge capability (0.8A–1.6A), and integrated safety vent protection, engineered for tactical LED flashlights, smart door locks, wireless audio equipment, laser pointers, and portable medical diagnostic devices.
Product Overview
The GEB 14500 3.7V 800mAh Cylindrical Lithium-ion Battery Cell (AA Size, 14×50mm) is an industrial-grade cylindrical cell manufactured to strict electrochemical tolerances for high-reliability electronic hardware. Featuring a 3.7V nominal voltage and 800mAh rated capacity (2.96Wh total energy), this cell incorporates a pressure-relief safety vent, precision steel can packaging, and low internal resistance (≤35 mΩ). With physical dimensions of Ø 14.5 ± 0.2 mm × H 50.5 ± 0.3 mm (AA Size); unit weight is confirmed for the selected configuration. 20g ± 1g, it is engineered for high-intensity LED flashlights, smart security locks, wireless microphones, laser rangefinders, and portable medical instruments. (Note: Due to its 3.7V nominal voltage, verify circuit compatibility before replacing standard 1.5V AA cells).

Equipment Compatibility & Engineering Fit Check
Before deploying GEB 14500 3.7V 800mAh Cylindrical Lithium-ion Battery Cell (AA Size, 14×50mm), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.7V / 800mAh 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.
