Never heard of a 14 volt battery. *12 volt batteries are normally
charged at 13-14 volts, so you normally see 14 volt "systems"
utilizing a 12 volt battery.

This is old school. Some radios designed for 13.8V nominal (which is
what a "12V" alternator provides) and did poorly on 12 and quit
entirely at 11.something, hence the 14V setup for gliders. It was
fairly common in the 1980s and I suspect my 20B was set up that way by
the original owner. Mine had a 10AH 14V pack consisting of two 6V 5
AH batteries plus two 4V 10AH batteries. Creative. Heavy. So when
they got tired, I switched to 12. Modern radios, by and large, work
just fine on 12V.
