18650 button top unprotected batteries are lithium-ion rechargeable cells featuring a raised positive terminal without an integrated protection circuit. These cells are commonly used in devices designed for button top batteries and applications requiring direct control of battery performance.
Button top designs provide improved contact in devices that require a protruding terminal, while unprotected cells are typically used in applications where external protection or device-level controls are in place.
Key Features
✔ Button Top Design – Raised positive terminal for reliable contact
✔ Unprotected Cells – No built-in protection circuit
✔ Lithium-Ion Chemistry – Rechargeable cells with consistent voltage output
✔ Standard 18650 Size – Compatible with devices designed for button top cells
Common Applications
✔ Flashlights & Portable Devices – Used in equipment requiring button top contact
✔ Battery Packs – Used in configurations where protection is handled externally
✔ High-Performance Applications – Suitable for devices requiring controlled output
✔ DIY & Custom Builds – Used in advanced battery setups
Unprotected vs Protected Cells
Unprotected batteries do not include an internal protection circuit. They are typically used in devices or systems that provide their own battery management or protection. Protected cells include built-in circuitry to help manage voltage and current.
Compatibility
Button top batteries should only be used in devices designed for button top cells. Always verify compatibility with your device, including size and terminal requirements.
Important Note
Unprotected lithium-ion batteries require proper handling and should only be used in compatible devices. Ensure your application includes appropriate safety and battery management measures.
