Panasonic 18650 Battery 3500mAh: The Quest for Maximum Capacity

Many corporate clients ask for the Panasonic 18650 battery 3500mAh version. While Panasonic officially lists batteries up to 3400–3450mAh (NCR18650B and NCR18650GA), it's important to note that any 3500mAh-labeled Panasonic battery should be verified for authenticity, as counterfeit products are common in the global supply chain.

Choosing the Right Panasonic 18650 Battery: Key Considerations

Criteria	NCR18650GA	NCR18650B
Capacity	3450mAh	3400mAh
Max Discharge Current	10A	~4.9A
Primary Use Case	High-drain devices	Long runtime, low-drain devices
Certified Performance	Yes	Yes

When sourcing Panasonic 18650 batteries, ensure you’re buying from reputable distributors with traceability and documentation (RoHS, UN38.3, MSDS). Counterfeit cells may not deliver stated capacity or current and can pose safety risks.

Conclusion

Companies seeking to integrate lithium-ion solutions into their product lines should evaluate these cells based on current draw, pack design, safety certifications, and lifecycle cost. When in doubt, consult with an experienced battery integrator for proper configuration and validation.
