 +===== Accumulator / battery operation =====
 +In the early days of radio heaters and plate batteries were almost the only usable voltage source in the field; in military thus, this situation remained the same for years to rund the equipment independant from mains power sources.
 +The old sets used accumulators for valve heating, usually high current and a voltage of 6.3 volts were used. Furthermore,​ the vlaves required different plate voltages, which could be delivered by anode or plate batteries, or care battery or mains operated converters.
 +Poprtable military equipment of the sixties mostly used heater batteries (1.5 volts as standard) and anode or plate batteries (special format, usually 51 or 103 volts).
 +The solid state sets from the seventies are battery operated and usually require standard battery types, with the exception of the widely used handheld Swiss "​walkie-talkie"​ SE-125 which requires a 7.5 volt battery; after these special batteries were out of stock, an adapter for use with standard UM3 / AA batteries has been developed. ​
