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 2600mAh at 11.1 volts and measures 66.90 x 55.46 x 21.55 mm. The pack weighs 145.2 g and includes a fully decoded chip that works like the original.

Practical Limits of the Lithium-Ion Pack

Capacity is fixed at 2600mAh and 28.86 Wh, so runtime matches the original specification. The chemistry requires operating temperatures below 60 °C / 140 °F and must not be disassembled or exposed to fire or water. A low-quality charger will shorten the usable life of the pack.

Installation and Common Issues

The pack fits the T7 enclosure using the existing connector; many online videos show the straightforward swap. The main risk is an improperly seated connector, which prevents charging or power delivery. The battery reaches its best performance after two or three full charge and discharge cycles. Buyers who need a different form factor or higher capacity cannot use this pack.

Questions about this item

Which capacity matches the original Bowers & Wilkins T7 J271/ICR18650NQ-3S battery?

This replacement delivers 2600mAh at 11.1V, matching the original 28.86Wh specification for the T7 speaker.

What does the 11.1V rating mean when the battery is inside the speaker?

It supplies the nominal voltage the T7's amplifier expects, so volume headroom and playback time stay as designed.

Does the pack use a standard 18650 interface or a proprietary connector?

The pack is built from 18650 cells with a fully decoded chip and the original connector, so it plugs straight into the T7 without adapters.
