How can I verify this is the correct battery before buying?

• Check the existing battery label for matching part numbers and voltage.
• Confirm the connector shape and screw positions match your laptop’s battery bay.
• When in doubt, reference your laptop’s exact model number (e.g., 15-CC1XX) for compatibility confirmation.
