D Size Batteries

A large-size battery, also called a D battery, is a cylindrical battery size with a markedly higher capacity than AA batteries. It is used in devices that draw high current or run on batteries for a long time, such as large flashlights, radios, water heater ignition units and toys. This category lists the Varta 1.5 V alkaline D battery; the IEC code of the alkaline D battery is LR20. Choose the battery size according to the D or LR20 marking in the device's battery compartment, the chemistry according to the device's current consumption, and the quantity according to the number of battery slots in the device. The D battery should not be confused with the C (medium-size) battery, which gives the same 1.5 V but is thinner and shorter; the two do not fit the same battery compartment.
