Mono (battery)
Mono, mono cell and D are common names for a standardized size of batteries and accumulators . With a diameter of 32.3 to 34.2 mm and a height of 59.5 to 61.5 mm, it is the largest of the common cylindrical round cells. The second value is the permissible maximum according to the IEC 60086-1 standard . The volume is about 49 to 56 cm³.
Monocells are manufactured with different electrochemical systems, which can differ significantly in nominal voltage , electrical capacity and load capacity. Depending on the system, other, often manufacturer-specific terms are used for non-rechargeable and rechargeable mono cells.
Monocells were mainly used in larger, portable electrical devices with relatively high energy requirements. Examples are toys , flashlights , portable cassette recorders , transistor radios and portable device combinations (especially radio recorders with a relatively high volume, so-called “ghetto blasters”). Due to the increased performance of alkaline-manganese batteries and the lower energy requirements of newer devices, smaller and lighter baby cells are often used today.
