Product Details
The GEB 18650 3.7V 1500mAh 15C Ultra-High-Drain Li-ion Battery Cell (22.5A Continuous) is a Grade-A cylindrical Lithium-ion power cell delivering a verified 3.7V nominal working voltage, 1,500mAh rated capacity (5.55Wh energy content), and an ultra-high continuous discharge rating of 15C (22.5A sustained continuous load). Built with low-impedance nickel-plated steel casing and integrated CID/PTC pressure-relief mechanisms, this power cell exhibits ultra-low AC internal resistance (≤ 14–18 mΩ) and tight pre-assembly grouping tolerances (ΔV ≤ 3mV, ΔR ≤ 1.5mΩ). Designed specifically for heavy-duty cordless power tools, garden machinery, and industrial vacuum cleaners, buyers must ensure pure nickel strip welding (minimum 0.15–0.2mm thickness) and appropriate cell holder ventilation during multi-cell module assembly.
Product Overview
The GEB 18650 3.7V 1500mAh 15C Ultra-High-Drain Li-ion Battery Cell (22.5A Continuous) is manufactured for demanding high-rate discharge applications requiring minimal voltage drop under severe peak loads. Delivering a solid 3.7V nominal operating voltage and 1500mAh rated capacity, it utilizes advanced cathode coating formulations to sustain up to 22.5A continuous and 30A peak pulse discharge currents. Standard physical dimensions are Ø 18.3 ± 0.2 mm × H 65.0 ± 0.3 mm with a calibrated unit weight of Approx. 44.0g ± 1.5g. Typical deployments include cordless circular saws, hammer drills, electric lawnmowers, emergency extraction equipment, and custom high-drain battery packs.

Equipment Compatibility & Engineering Fit Check
Before deploying GEB 18650 3.7V 1500mAh 15C Ultra-High-Drain Li-ion Battery Cell (22.5A Continuous), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.7V / 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 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.
