I use an Odyssey battery charger for my PC680 to maintain the battery. Occasionally I turn on the Garmin avionics while the charger is connected. I recently heard that the desulfurization circuitry is bad for an internal fuse in the avionics. Does anyone know about this?

Most desulfurization circuits send an occasional high voltage spike down the

charger leads.  This only lasts for a few milliseconds.  However, the high

voltage spike could lead to a couple of milliseconds of high current.   This

should not damage most fuse/circuit breakers, however, there might be some

out there that could be damaged.
