Archived from the original (PDF) on 12 March 2012. {{ cite web}}: Missing or empty |title= ( help)This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. This battery contained two independent 4.5V batteries, and had a four-pin connector. 9V with a center tap was available by wiring in series. There were two ⌀3.2mm negative pins spaced 9.5mm apart and two ⌀4.0mm positive pins spaced 14.3mm apart. Negative and positive pins were spaced 18.1mm apart. It was used in some early transistor radio amplifiers with a Class B output stage, allowing the loud speaker to be connected between the amplifier output and the battery center tap.
