Replacement Battery for Bowers & Wilkins T7

This lithium-ion pack replaces the original J271/ICR18650NQ-3S cell inside the Bowers & Wilkins T7 speaker. It delivers 2600mAh at 11.1 volts and matches the factory dimensions of 66.90 x 55.46 x 21.55 mm. The integrated decoded chip communicates with the speaker exactly like the original battery.

Owners needing a direct-fit T7 power cell

Suitable for users whose T7 no longer holds a charge and who can follow a disassembly guide. Not for buyers who want a higher-capacity upgrade, a different voltage, or a battery for another speaker model. The pack is a one-to-one replacement only.

Simple swap with basic tools

Installation videos are widely available and show the connector plugging straight into the speaker board. The main risk is seating the connector incorrectly or damaging the ribbon cable during reassembly. A few full charge-discharge cycles settle the capacity to its rated 28.86 Wh.

Questions about this item

Do I need the original Bowers & Wilkins J271/ICR18650NQ-3S battery to match the connector on this 11.1 V replacement?

Yes, the replacement uses the same connector as the original J271/ICR18650NQ-3S pack, so the speaker must accept that exact plug.

Will the 66.90 x 55.46 x 21.55 mm dimensions fit the existing T7 battery compartment?

The pack measures 66.90 x 55.46 x 21.55 mm, matching the original T7 cavity, so it sits in the same space without modification.

How can I confirm the 2600 mAh pack is working correctly after the first few charges?

After two or three full charge and discharge cycles the battery reaches its rated 2600 mAh capacity and the speaker runs for the expected playback time.
