Product Details
The GEB 18650 3.2V 1800mAh Cylindrical LiFePO4 Battery Cell (18×65mm) is a professional-grade, high-reliability Lithium Iron Phosphate (LiFePO4) cylindrical cell delivering a verified 3.2V nominal working voltage and 1,800mAh rated capacity (5.76Wh energy). Built with chemically stable olivine LiFePO4 chemistry and an integrated pressure-relief safety vent, this cell delivers extraordinary thermal stability, resistance to thermal runaway, an ultra-flat 3.2V voltage plateau, and prolonged service endurance (≥ 2,000–3,500 cycles at 80% DoD). It is engineered for solar street lighting modules, electric mobility packs, and commercial backup energy storage.
Product Overview
The GEB 18650 3.2V 1800mAh Cylindrical LiFePO4 Battery Cell (18×65mm) is an industrial cylindrical cell manufactured to strict electrochemical tolerances for high-reliability cyclic applications. Featuring a 3.2V nominal voltage and 1800mAh rated capacity, this cell incorporates a heavy-duty nickel-plated steel canister, PTC thermal element, and safety vent. With physical dimensions of Ø 18.3 ± 0.2 mm × H 65.0 ± 0.3 mm; unit weight is confirmed for the selected configuration. 42.0g ± 1.5g, it is engineered for solar street lighting, cordless power tools, electric scooters, AGVs, and modular energy storage systems. Before pack spot-welding, verify nickel tab thickness, cell spacing holders, and charger cutoff calibration (3.65V LiFePO4 CC/CV algorithm).

Equipment Compatibility & Engineering Fit Check
Before deploying GEB 18650 3.2V 1800mAh Cylindrical LiFePO4 Battery Cell (18×65mm), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.2V / 1.8Ah 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 3.65V.
- 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.
