Protected vs Unprotected Cells
Protected batteries include an internal protection circuit designed to monitor voltage and current conditions. Unprotected cells do not include this circuitry and are typically used in applications with external battery management systems.
Compatibility
Button top protected batteries are often longer than standard cells due to the added protection circuit. Always verify compatibility with your device, including size and terminal requirements.
Important Note
Use only with compatible devices and chargers designed for lithium-ion batteries. Ensure your device supports protected cells before use.
