Introduction
This bike-to-bike intercom system was given to me by a friend for repair. He is an avid bike rider and purchased this set a while ago but did not have time to ever use it. Once he did try to charge it it would not take a charge. I assumed that it was the batteries since they have never been charged. They may have been depleted below the threshold of where they would accept a charge. When he called the cardo support number he was told that "There is no out of warranty service for scala rider batteries." He would need to purchase a new scala rider headset in this case. Really? Lets check this myth about the "not user serviceable" battery.

Insert a small guitar pick or similar tool to separate the individual halves. Start by the charging port end since this seems to be a better entry and not quite as tight.
