Troubleshooting Neptune Processor Water Leak | Battery Compartment

By Eric Sherman

My son uses an Advanced Bionics Neptune sound processors daily.  We have a white battery cap for the left side, and red battery cap for the right.  This was the easiest way for us to know which processor was programmed for which side of the head.

We found over time water leaked into the battery compartment, and the battery would begin to rust.  This was very concerning to us.  We thought how could the seal start breaking down so quickly?  What we discovered was the battery cap was cracked. 

We found the cap had developed a micro crack on the end.  You could only see it when you pulled outward on the sides of the cap (pictured). The crack most likely developed over time from daily use, and from attaching the processor clip.

We decided to replace the daily use caps with new caps dedicated just for swimming. We picked a different color not to mix up the caps.  Ever since we started changing caps for swimming, we have not had any problems with water leaks.

If you find water getting into your battery compartment, check for small cracks and make sure the gasket around the processor is free of debris.  Also, consider using different caps when swimming if you use the Neptune processor for everyday use.   

The great thing about the Neptune processors, they are waterproof and  very durable.  After we wiped dry the battery compartment, we  inserted another battery and it worked just fine. We do recommend, as the manufacturer suggests, to use the dehumitifer to  dry out the processors after water use.
