### **2. Panasonic Battery Model Analysis**
#### **A. Lithium-Ion (Li-ion) Cylindrical Cells**
1. **NCR18650GA**
- **Chemistry**: Li-ion (Nickel Cobalt Aluminum Oxide, NCA).
- **Capacity**: 3,450mAh (high-energy density).
- **Voltage**: 3.6V nominal, 4.2V max.
- **Applications**: Consumer electronics, power banks, light EVs.
2. **NCR18650B**
- **Chemistry**: Similar NCA chemistry.
- **Capacity**: 3,400mAh (slightly lower than GA).
- **Key Trait**: Balanced energy/power; older but widely used.
3. **NCR18650PF**
- **Chemistry**: Li-ion (lower cobalt, cost-optimized).
- **Capacity**: 2,900mAh but higher **continuous discharge** (10A vs. GA’s 6.8A).
- **Use Case**: High-drain devices (e.g., vaping, power tools).
#### **B. Non-Rechargeable Coin Cell**
- **BR1225**
- **Chemistry**: Lithium Carbon Monofluoride (Li-CFX).
- **Voltage**: 3V, low self-discharge.
- **Applications**: Memory backup, small electronics.
#### **C. Prismatic/Pouch Cell (Less Common)**
- **NCA103450**
- **Format**: Likely prismatic (10mm x 34mm x 50mm).
- **Chemistry**: NCA (high energy, possibly for specialized devices).
- **Note**: Rare in public datasheets; confirm specs with Panasonic directly.
---
### **3. Key Considerations for Buyers**
- **Authenticity**: Panasonic cells are heavily counterfeited. Request **batch codes** and test reports.
- **Compatibility**: Ensure models match your device’s voltage, capacity, and discharge requirements.
- **Regulatory**: Check for UL/IEC62133 compliance for safety-critical applications.
---
### **4. Recommendations**
- **For High Capacity**: Choose **NCR18650GA** for energy density.
- **For High Discharge**: **NCR18650PF** is better suited.
- **Supplier Due Diligence**: Audit Fullybest’s supply chain or opt for Panasonic-authorized distributors like **FULLYBEST ELECTRONICS HK LIMITED**
