The S2 owner's book lists a battery charger as "optional", and says it
is "activated from the 100v switch panel". Mine is an after market
installation for sure. My battery charger is a Ray Jefferson model
"15-3"? Regulated D.C. Battery Guard, for mounting on a vertical
surface. It's hung on the back of the bulkhead behind the head,
starboard side, and has a simple three prong cord to plug into the
duplex outlet in the head. I'm on a mooring so it hardly ever gets used.
