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 capacity at 11.1 volts for 37.74Wh total energy. The 146.0g unit matches the factory dimensions of 66.50 x 55.00 x 21.20mm. A decoded chip ensures the speaker recognises the pack exactly like the original.

Physical and electrical limits of the pack

The battery fits only devices that accept the 66.50 x 55.00 x 21.20mm form factor and the 11.1V three-cell layout. Capacity is fixed at 3400mAh; runtime scales with the speaker's actual draw. The protection circuit guards against overcharge, over-discharge, over-voltage and short circuit. Storage above 60 Celsius or 140 Fahrenheit is not permitted.

Upgrading from a depleted or failing original cell

When the factory pack no longer holds charge or the speaker shuts down prematurely, this unit restores the original 3400mAh specification. It is not a higher-capacity alternative, so owners seeking longer playtime will not gain extra hours. The jump is worth it only when the existing battery has degraded below usable performance.
