Bose SoundLink Color I / Color II Battery Replacement Guide – 064541

Bose SoundLink Color speaker losing charge sooner than it used to, or refusing to power on after charging? Check the power supply and model-specific troubleshooting before deciding the battery needs replacement.

Aging batteries can shorten playback time, but charging cables, USB ports, firmware, and internal electronics can cause similar symptoms. This guide helps SoundLink Color I and Color II owners plan a repair without assuming the two models have identical internal construction.

Replacement Option: STARNOVO 3.7V 2600mAh Replacement Battery for Bose SoundLink Color I / Color II, listed with references R-41027073, 01701-9168, and 064541. Confirm the original pack and electrical connections before ordering.

1. Technical Specifications & Compatibility

The STARNOVO product lists these replacement specifications:

  • Listed Applications: Bose SoundLink Color I and SoundLink Color II Bluetooth speakers
  • Listed Battery References: R-41027073, 01701-9168, 064541
  • Nominal Voltage: 3.7V
  • Rated Capacity: 2600mAh
  • Chemistry: Lithium-ion
  • Protection: The listing specifies an integrated PCM for overcharge, over-discharge, overcurrent, and short-circuit protection.
  • Package Contents: One replacement battery

This is a third-party STARNOVO battery, not an original Bose product. The references above are those listed for this replacement; check the markings and configuration of your actual pack rather than relying on a reference alone.

The current product description does not provide numeric dimensions. Before installation, compare the complete assembly's size, insulation, mounting arrangement, leads or tabs, polarity, and any additional connections. Do not assume a generic 3.7V cell is equivalent to a complete replacement assembly.

Model Identification Note: SoundLink Color I and Color II require their own repair information. Do not apply these battery listings or procedures to SoundLink Mini, Revolve, Flex, or other Bose speakers.

2. Battery Aging or a Charging Fault?

Reduced runtime may be consistent with battery aging, but a speaker that will not charge needs further diagnosis before a battery is purchased.

  • Check the Cable and Power Source: Use a suitable known-working cable and supply according to the manual for your speaker.
  • Inspect the Charging Port: Look for visible damage or contamination without inserting metal tools.
  • Observe Color II Charging Indicators: Bose describes a flashing amber battery indicator during charging and solid green when charging is complete.
  • Review Official Troubleshooting: Bose has documented a Color II software-related charging and power issue addressed through its updater. Follow the applicable official instructions before assuming the cell is faulty.

If the battery becomes unusually hot, leaks, swells, or pushes the enclosure apart, stop using and charging the speaker. Do not compress or puncture it. Seek qualified repair assistance.

3. SoundLink Color Battery Replacement — Repair Planning Checklist

This is not necessarily a connector-only swap. If the repair requires soldering or work on a battery assembly, use a qualified electronics technician. Do not solder directly to a bare cell, bypass protection components, or substitute an unverified generic cell.

  1. Confirm the Speaker: Identify Color I or Color II using the actual model label and review the matching repair guide.
  2. Check Support Options: Consult Bose support before choosing an independent repair. Battery removal instructions intended for disposal must not be treated as installation instructions.
  3. Disconnect Power: Turn off the speaker and unplug charging and audio cables before internal work.
  4. Follow the Correct Access Sequence: Do not assume both models have the same covering, fasteners, or internal layout. Avoid pulling housing parts against attached wires.
  5. Document the Original Assembly: Photograph battery markings, connection positions, insulation, cushioning, and cable routing before disturbance.
  6. Compare Before Installation: Verify voltage, dimensions, terminal arrangement, polarity, protection, and all leads. Stop if a forced fit or unexplained wiring change would be required.
  7. Protect the Cell and Connections: Do not cut into the battery wrap, pry metal tools against the cell, or apply heat directly to it. Have soldered or tabbed connections handled by a qualified technician.
  8. Reassemble Carefully: Restore appropriate insulation and secure mounting without compressing the battery. Keep wires clear of fasteners and seams, and check that the enclosure closes without force.

Color II Seal Warning: The independent guide warns that opening the covering can affect protective microphone foam and water resistance. Reassembly alone does not verify restoration of the original protection. Do not test the repaired speaker by exposing it to water.

4. What to Expect After the Swap

If battery aging caused the fault, a suitable replacement may improve usable runtime. It will not fix a faulty USB port, damaged charging circuit, firmware problem, or defective speaker driver.

  • Charge After Reassembly: Follow the instructions for the exact model and stop if unusual heat, odor, swelling, or unstable behavior occurs.
  • Check Controls and Indicators: Verify normal startup, buttons, and charging behavior.
  • Test Audio: Pair with a familiar device and listen at moderate volume for stable playback or unexpected rattles.
  • Check Unplugged Operation: Confirm the speaker operates after external power is removed.
  • Measure Actual Runtime: Compare similar volume and use conditions. A 2600mAh rating does not by itself guarantee all-day playback or a fixed number of hours.

5. Common Mistakes to Avoid

  • Confusing SoundLink Models: Color I and Color II are not interchangeable teardown instructions.
  • Expecting Every Battery to Plug In: Inspect the actual connection method before starting.
  • Replacing an Assembly with an Unverified Bare Cell: Capacity and nominal voltage alone do not establish suitability.
  • Reversing Polarity or Omitting Connections: Document the original electrical arrangement and stop if anything is unclear.
  • Damaging Insulation or Cushioning: Restore appropriate protection rather than leaving the assembly loose.
  • Assuming Water Resistance Is Restored: A closed enclosure is not a verified seal.

6. Choosing Your STARNOVO Replacement Battery

The STARNOVO replacement is listed for SoundLink Color I / Color II with a nominal voltage of 3.7V and capacity of 2600mAh. Confirm the full assembly configuration and fit against the original before installation.
