Product Details
The GEB IFR18650 3.2V 1500mAh LiFePO4 Cylindrical Battery Cell (18×65mm) is an industrial Grade-A Lithium Iron Phosphate (LiFePO4) cylindrical cell delivering 3.2V nominal operating voltage, 1,500mAh rated capacity (4.80Wh total energy), and extreme cyclic endurance exceeding 2,000–3,500 cycles at 80% DoD. Utilizing intrinsically safe olivine-structure LiFePO4 cathode chemistry and a heavy-duty steel casing with pressure-relief venting, this cell provides superior thermal runaway immunity up to 270°C. With a continuous discharge capability of 3C (4.5A) and peak pulse of 8C–10C (12A–15A), it is the premier selection for solar street lighting, commercial emergency power units, UPS backups, and light electric mobility. Before pack assembly, verify charger cutoff voltage calibration strictly at 3.65V per series cell.
Product Overview
The GEB IFR18650 3.2V 1500mAh LiFePO4 Cylindrical Battery Cell (18×65mm) is manufactured for applications requiring uncompromising safety, wide temperature tolerance, and long multi-year service life. Featuring a stable 3.2V nominal voltage plateau and 1500mAh rated capacity, it features physical dimensions of Ø 18.3 ± 0.2 mm × H 65.0 ± 0.3 mm and a calibrated unit weight of Approx. 43.0g ± 1.5g. Unlike cobalt-based chemistries, LiFePO4 exhibits zero oxygen release under overcharge or physical puncture. Key applications include solar LED street lamps, lawn lighting, telecom backup stations, electric power wheelchairs, and marine navigation aids.

Equipment Compatibility & Engineering Fit Check
Before deploying GEB IFR18650 3.2V 1500mAh LiFePO4 Cylindrical 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 / 1.5Ah 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.
