18350 Battery & Charger – Compact High-Power Li-ion Cells + Dedicated Chargers, Small but Mighty Power Combo
Welcome to our 18350 Battery & Charger collection. The 18350 lithium-ion cell (approx. 18mm diameter × 35mm length) is the "short sibling" of the 18650, reducing length by nearly half while maintaining the same 18mm diameter. This compact design fits space-constrained devices while retaining the core advantages of cylindrical cells: robust construction, excellent heat dissipation, and superior consistency. This collection offers a full range of 18350 cells—including high-drain NMC/INR and inherently safe LiFePO₄—with capacities from 700mAh to 1200mAh and high-drain models supporting 10A–15A continuous discharge. Paired with dedicated Li-ion chargers compatible with 18350/18650/16340 and more. Ideal for mini flashlights, compact vape mods, headlamps, laser rangefinders, portable medical devices, and micro RC models.
Core Advantages of 18350 Batteries
- Ultra-Compact Form Factor: At just ~35mm long—30mm shorter than an 18650—the 18350 fits into extremely tight spaces, enabling device miniaturization.
- High Power Density: Despite modest capacity, high-drain 18350 cells deliver 10A–15A continuous discharge, offering power-per-volume rivaling larger formats.
- 18650 Ecosystem Compatible: Shared 18mm diameter allows charging in many 18650 chargers (verify length compatibility).
- Flexible Chemistry Options: Available in high-drain NMC/INR and inherently safe LiFePO₄ formulations.
- Rechargeable – Economical: Supports 500–1,000+ cycles for low long-term cost.
Core Advantages of 18350 Dedicated Chargers
- Precision Charging Management: CC/CV profile with automatic battery type detection and auto-termination.
- Multiple Safety Protections: Overcharge, over-discharge, overcurrent, short-circuit, reverse polarity, and overheat protection.
- Wide Size Compatibility: Supports 18350, 18650, 18500, 16340, 14500, and more—one charger for multiple formats.
- Independent Charging Channels: Multi-bay chargers control each slot independently—mix cells of different charge levels.
- LCD Digital Display: Real-time monitoring of voltage, current, and charged capacity.

⚠️ 18350 Battery & Charger Safety Guidelines
- Voltage Platform Awareness: 3.2V LiFePO₄ and 3.7V NMC cells cannot be mixed or charged with the same settings. Verify charger mode before charging.
- Length Compatibility: 18350 cells are shorter than 18650s. Some 18650 chargers may not hold them securely—use a universal multi-size charger.
- Limited Capacity – Plan for Runtime: 18350 capacity is only 1/4 to 1/3 that of 18650s. Consider carrying spare cells for high-drain devices.
- Use a Quality Charger: Always use a reliable charger designed for Li-ion or LiFePO₄ chemistry.
- Avoid Over-Discharge: Stop discharging when voltage drops below 2.5V–2.8V (NMC) or 2.0V–2.5V (LiFePO₄). Recharge promptly.
- Avoid Short Circuits and High Temperatures: Do not short the terminals. Keep away from fire, heat, and moisture.
- Discontinue if Damaged: Stop using cells with torn wraps, dents, or leakage. Recycle responsibly.
