Many pieces of amateur radio equipment run on 12-volt DC automotive voltage, which is also called 13.8-volt DC. The voltage delivered by a lead–acid battery with six-cells used as an automotive battery will vary depending on various electrical loads in a vehicle. Without loads the battery will float from 11.7 to 12.8 volts, and while charging ...
