The pack uses an INR18650-3S1P cell configuration and includes a fully decoded chip for correct communication with the speaker.

Suits owners needing a direct swap

Buyers who want a drop-in replacement for a worn-out DOCKIN speaker battery will find the matching voltage, capacity and connector. Users whose speaker uses a different part number or physical layout should look elsewhere, as this pack is built to the exact dimensions of 69.40 x 55.10 x 19.40mm for the listed models only.

Verify model and part number first

Before ordering, confirm the speaker model is D Fine, D Fine 2 or D Fine+ 2 and that the original battery carries part number INR18650-3S1P. Check that the existing pack measures 69.40 x 55.10 x 19.40mm and weighs approximately 146.0g. Ensure the connector orientation matches the replacement.

Questions about this item

Which DOCKIN speaker models accept this 2600 mAh 11.1 V lithium-ion pack?

It is a direct replacement for the DOCKIN D Fine, D Fine 2 and D Fine+ 2 when the original part number is INR18650-3S1P.

Will the battery fit if my speaker still uses the factory connector and mounting points?

Yes — the pack measures 69.40 × 55.10 × 19.40 mm and uses the same connector, so it slots into the existing compartment without modification.

How can I confirm the new cell is operating correctly after the first few charge cycles?

After two or three full charge-and-discharge cycles the speaker should reach its normal playtime and the pack voltage will settle at 11.1 V under load.
