Buying Guide
Confirm the exact part number
Bose batteries are often model-specific, and the same product name can hide different internal packs across revisions. Look for a part number printed inside the battery compartment or on the original cell, then match it against the listing. Owners frequently report that matching part numbers prevents most fit problems.

Capacity (mAh)
Listed capacity in milliamp-hours indicates how much charge the cell can hold. Higher numbers generally mean longer runtime between charges, assuming the voltage matches. Compare capacity only between batteries with the same voltage and form factor, since mismatched specs can affect performance.

Voltage match
Voltage should match what your headphones expect. Listings in this group specify 3.7V or 3.8V. Using the wrong voltage can cause poor performance or damage, so treat the voltage printed on the original battery as the reference point.

Pack size and spares
A single cell is enough for a one-time repair. Two-packs make sense if you want a spare on hand or manage more than one pair. Consider how often you travel or use the headphones daily, since a backup can prevent downtime.
Good picks for this: Fits 40228, 40229, PC40227, PC40229 and NTA2358 (2-Pack)
Installation difficulty
Most replacements require opening the earcup or housing, which usually involves small screws, adhesive, and fragile ribbon connectors. Plan for a clean workspace, small driver bits, and patience. If you are not comfortable with electronics repair, a professional repair service may be a safer route.

Safety and handling
Lithium-based cells can overheat or swell if punctured, overcharged, or stored improperly. Keep replacement batteries away from heat, do not charge unattended, and recycle damaged cells at an approved facility. The U.S. Consumer Product Safety Commission publishes guidance on lithium battery safety. Consult a qualified professional if a battery looks swollen or leaks.

FAQ
How do I know which replacement battery for Bose headphones I need?
Find the model name and part number inside your headphones, on the original battery, or in your Bose product documentation. Match that information to the compatibility details in the listing before ordering.
How long does a replacement battery usually last?
Lithium-based cells typically decline in capacity over hundreds of charge cycles. Runtime depends on the cell’s age, usage habits, and how the battery was stored. Results vary, and no listing can guarantee a specific lifespan.
Can I replace the battery myself?
Many owners do, but it requires opening the housing, handling small components, and working with a lithium cell. If you lack experience with electronics repair, a qualified repair technician is the safer option.
Will replacing the battery void my warranty?
Opening the housing may affect warranty coverage. Review your Bose warranty terms or contact Bose support before starting a DIY repair.
Is a higher mAh rating always better?
A higher listed capacity usually means longer runtime, but only if the voltage matches and the battery physically fits. Mismatched voltage or form factor can cause problems regardless of capacity.
What should I do with the old battery?
Do not throw lithium batteries in household trash. Take them to a battery recycling drop-off or a retailer with a take-back program. Damaged or swollen cells should be handled with extra care.
Conclusion
For most owners of QuietComfort 35 and QC45 headphones, the New Battery Replacement Battery for Bose QC35 QC45 QuietComfort 35 II offers the broadest model coverage. Owners of older QuietComfort 3 models should prioritize the listing whose part numbers match their own. The NC700 battery stands out for higher listed capacity, while the AOLIKES option suits budget-minded owners of older Bose headsets. Confirm the part number, match the voltage, and plan the installation carefully before ordering.
