Due to a prolonged period of non use the 24V battery went flat on my
C172N. Is there any way a charger can be connected through the
external power point rather than the hassle of removing cowls to
connect battery charger alligator clips. It could be handy to connect
a trickle charger ocassionaly during long periods of non use? Arthur

Not positive about the 172N, but most external power plugs are designed to
deliver current to the starter, not the battery. I've seen a few different
designs. With some you need to leave the master off to start, some you don't.
One thing they did have in common is that they typically bypassed the battery,
making the connection unsuitable for battery charging. There should be a
schematic for the external power plug in the flight manual. You should have
a look.
