Cylindrical cells: KR or HR followed by a letter indicating discharge rate (L, M, H or X for low, medium, high and very high, respectively); then another letter may be added to indicate use at elevated temperatures (T or U) or rapid charge (R); then maximum diameter in mm / maximum height in mm. E.g. KRL 33/62, HRHR 23/43
This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. In Switzerland as of 2008, 4.5-volt batteries account for only 1% of primary battery sales. [89] PP3, 9-volt, or E [90] Radio battery Smoke alarm battery Square battery Transistor battery 006P MN1604

The design for U-Battery was created at Delft University of Technology in the Netherlands and Manchester University in the United Kingdom basing it on high temperature reactor (HTR) technology which was already available in Europe. [3]
For a circuit using a battery source, the emf is due solely to the chemical forces in the battery. For a circuit using an electric generator, the emf is due solely to a time-varying magnetic forces within the generator. Both a 1 volt emf and a 1 volt potential difference correspond to 1 joule per coulomb of charge.
