Installation Notes

The pack uses a fully decoded chip so the device recognises it immediately. Many online videos demonstrate the swap, which typically involves opening the battery compartment and disconnecting the old connector. Take care not to puncture the soft pouch and verify the polarity before seating the new cell.

Pre-Order Checks

Confirm your instrument is an EXFO FIP-425B or FIP-435B and that the original battery carries one of the listed part numbers. Measure the available space against the 50.80 x 30.00 x 23.50mm dimensions to ensure the compartment lid closes properly.

Questions about this item

How do I confirm the replacement battery is working correctly after installing it in my EXFO FIP-425B?

The package includes the lithium-polymer cell measuring 50.80 x 30.00 x 23.50 mm with protective foam; no additional components are required for installation.

Which part numbers does this 3600mAh cell replace for the FIP-425B and FIP-435B?

It replaces EXFO 880X268, GP-2226 and XW-E416 across both models.
