FAQs About Buying and Using 18650 Batteries in Bulk

Learn more about buying and using 18650 batteries in bulk through our frequently asked questions.

What’s the difference between protected and unprotected 18650 batteries?

Protected 18650 batteries include a built-in circuit for overcharge, over-discharge, and short-circuit protection. Unprotected cells offer raw performance but require external battery management systems.

Can I get 18650 batteries with specific discharge ratings?

Yes! Voltaplex offers 18650 battery cells with various discharge rates to support different system requirements.

How should I store 18650 batteries in bulk?

Store 18650 batteries in a cool, dry location away from metal objects, direct sunlight, or heat sources. Keep them partially changed and use protective cases for long-term storage. 

Do 18650 battery cells have a shelf life?

Yes, most 18650 cells maintain optimal performance for 2 to 3 years if stored properly. Gradual capacity loss can occur over time due to natural chemical aging. 

How Cylindrical Form Factors Benefit Custom Battery Designs

The uniform shape and standard dimensions of 18650 batteries simplify the custom battery pack assembly layout process. 

Engineers can scale systems easily by aligning multiple 18650 cells in fixed arrays without adjusting for variable dimensions. 

This form factor allows precise capacity planning, simplifies connection points, and supports automation in high-volume builds. 

Voltaplex offers 18650 battery cells in bulk to meet the needs of teams developing modular, repeatable designs.
