    • Turn the earpiece over, and expose the battery by folding the microphone and cover plate away from the battery housing.

    • Desolder battery connections to disconnect the three colored wires from the old battery. Make note of corresponding colors/locations for installation of new battery.

    • Carefully remove the old battery by wedging a plastic opening tool or spudger underneath the battery to release the adhesive.

    • Do not bend or puncture the battery housing.

    • For reassembly, follow steps 1-4 in reverse order:

    • Take care to ensure battery wires are soldered correctly with each color on its corresponding pad.

    • Use minimal amounts of adhesive to re-attach the speaker foam to avoid glue making a mess.

Conclusion

Be sure to test your new battery to make sure the fix succeeded.

Could you post the dimensions of the battery itself? Seems like it's hard to find one that may or may not fit. That or could you recommend where to get a battery?

So, which battery is the best replacement for the original? Is it possible to put some bigger batteries inside with some modding?

Battery sizes are mAH, just by a 900 or more and that should do the trick. The actual size of the battery must be identical for a perfect fit and confortable headsets. Just make sure you get the correct voltage and size.

The battery comes with a cable, instead of soldering, can I tie those cables in? Also, what is the best way to remove and reattach foam cushions without damaging them?
