Replacement Battery for Bowers & Wilkins T7

This 3400mAh lithium-ion pack is built to replace the original J271/ICR18650NQ-3S cell in the Bowers & Wilkins T7 portable speaker. It delivers 11.1V and 37.74Wh to restore full runtime for owners whose factory battery no longer holds a charge.

Compact 66.50 x 55.00 x 21.20mm housing

The pack fits the T7 battery compartment without modification and the fully decoded chip communicates with the speaker electronics exactly like the original. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuit for safe daily use.

Direct swap for a depleted OEM cell

It replaces the worn-out factory battery when runtime has dropped noticeably or the speaker shuts down unexpectedly. The upgrade is worth it when the T7 otherwise functions perfectly but can no longer sustain portable playback.

Questions about this item

What voltage and capacity does this 11.10 V lithium-ion pack deliver?

The pack is rated at 11.10 volts and 3400 milliamp-hours, giving 37.74 watt-hours of energy.

Will the 66.50 x 55.00 x 21.20 mm case fit inside my Bowers & Wilkins T7?

Those are the exact dimensions of the original J271/ICR18650NQ-3S pack, so it matches the T7 battery compartment.

Which way round does the connector go when I slot the new pack in?

Align the plug with the socket — forcing it backwards is the common mistake that bends pins.
