Replacement Battery for Bowers & Wilkins T7

This lithium-ion pack replaces the original J271/ICR18650NQ-3S cell in the Bowers & Wilkins T7 speaker. It delivers 3400mAh at 11.1V for 37.74Wh of energy storage. The physical footprint measures 66.50 x 55.00 x 21.20mm and weighs 146.0g. A fully decoded chip ensures communication with the speaker matches the factory unit.

Sustained playback performance

The 3400mAh capacity supports extended listening sessions between charges rather than brief bursts. Integrated protection circuits guard against overcharge, over-discharge, over-voltage and short-circuit events during continuous use. The pack is designed to reach its best runtime after two or three complete charge and discharge cycles. Operating or storage temperatures above 60°C or 140°F are not supported.

Compatibility and installation limits

Fit is confirmed only for the Bowers & Wilkins T7 with part number J271/ICR18650NQ-3S; other models or part numbers are not supported. The connector must be seated correctly during installation for the decoded chip to function. A low-quality third-party charger can reduce the pack’s service life. Disassembly, exposure to fire or water, and storage above the stated temperature ceiling are prohibited.

Questions about this item

Does the 11.1 V lithium-ion pack run hot or draw extra power when the Bowers & Wilkins T7 plays all day?

The replacement cell matches the original 11.1 V 3400 mAh specification, so thermal behaviour and power draw remain the same as the factory battery.

What must I already own to install this 66.50 x 55.00 x 21.20 mm pack in my T7 speaker?

You need the Bowers & Wilkins T7 speaker itself and basic tools to open the battery compartment; the pack includes a pre-fitted connector and decoded chip.

Will this 37.74 Wh battery work alongside the original charger and circuitry I already use with my T7?

Yes, the fully decoded chip communicates with the existing charging circuit exactly like the original J271/ICR18650NQ-3S pack.
