How do I confirm this battery fits my Dell model?

Check your current battery label and part number by opening the laptop’s bottom cover or reviewing system hardware information. Match one of the listed compatible part numbers (for example DWVRR, 817GN, 0NR6MH) and ensure your Inspiron 16 7620 2-in-1 uses the 6-cell DWVRR variant rather than a different TN70C 4-cell type.

• Open the back panel to read the battery sticker part number.
• Compare to compatible numbers: DWVRR, 817GN, 0017GN, 0NR6MH, etc.
• Confirm physical battery shape and connector match the bay.
• If unsure, check your service manual or contact ZTHY support.
