Fit, protection and charging

This protected cell includes a protection circuit. Protected assemblies can be longer than bare cells of the same nominal size. Check the complete dimensions and terminal shape against your device.

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.

Technical documents

Where a document describes the underlying bare cell, its dimensions and electrical limits do not automatically apply to the protected assembly. Match the complete protected battery and its protection-circuit limits to your equipment.
