Fit, protection and charging
This is an unprotected cell. It requires appropriate protection in the equipment or battery pack. It is intended for suitable applications designed to manage charging, discharge current and cell voltage.
A matching cell size alone does not establish compatibility. Follow the cell and equipment documentation for charging voltage, current and temperature limits. Do not use damaged cells or carry loose cells with metal objects.
Compare battery chargers, then confirm the exact chemistry, charging voltage and physical fit in the charger manual.
