Charging, protection and fit
Use a charging system specified for this cell’s lithium-ion chemistry and 4.2V maximum charge voltage. Follow the cell documentation for current, temperature and discharge limits. Battery size alone does not establish compatibility: check the complete cell dimensions, flat-top contact and protection requirements.
Keep individual cells in an insulating battery case. Do not use a cell with a damaged wrapper or insulator, or carry loose cells with metal objects.
