🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Restore the reliable battery performance of your WH-1000XM6 noise-cancelling headphones with this 633741 1050mAh replacement battery.

Its battery is designed to provide up to 30 hours of playback with ANC enabled, making it a critical component for daily commutes and long listening sessions. After regular charging cycles, the original cell may show signs of aging, such as shorter runtime, sudden shutdowns during use, slower charging, or a swollen battery compartment. This 1050mAh Li-ion battery with a 3-pin connector is a direct replacement designed to bring back full wireless playback time.
Wiring Polarity Note: This battery comes with a 3-pin connector featuring colored wires. Please note that the red wire is the positive (+) terminal and the black wire is the negative (-) terminal. Ensure you connect the wires with the correct polarity during installation to avoid damaging the battery or your device.

It is factory-tested and carries CE, RoHS, and UN38.3 certification.

Compatibility Note: This 633741 1050mAh Li-ion battery is a direct replacement for the WH-1000XM6 headphone. It features a 3-pin connector that matches the original battery interface. Please confirm your original battery label shows 633741 before ordering. Because third-party replacement batteries can vary by batch, professional installation is recommended for this sealed headphone housing. Using an incorrect battery may cause improper fit or charging issues.
Battery Care Tips: Use a compatible charger, avoid extreme heat or cold, and try not to drain the battery to 0% often. For daily use, keep the battery level between 20% and 80% when possible. If you store the headphones for a long time, keep the battery at around 50%. After replacing the battery, check that the earcup housing is reassembled correctly. If you are not confident, ask a professional technician to do the replacement.
