- Can accommodate an approximately 18.5mm × 67.5mm battery
- Is designed to operate safely with an unprotected 18650 cell
Important Safety Information
These are UNPROTECTED 18650 Li-ion cells and do not have a built-in protection circuit.
These cells are intended to be installed in compatible equipment or a protective enclosure that prevents user access to the cells and associated circuitry during charging and discharging.
Use only with equipment that provides the appropriate battery protection and charging controls required for Li-ion cells.
Do not use these batteries as replacements for protected 18650 batteries unless the device is specifically designed for unprotected cells.
Do not short-circuit, puncture, crush, disassemble, expose to excessive heat, or use a damaged battery. Use only a compatible Li-ion charger or charging system.
