Torches with C batteries
C
— 1.5-volt cylindrical batteries with dimensions of 50x26.2 mm; approximately equal in length to "finger" AA, but much thicker, due to which they have a much larger capacity. Some time ago they were quite popular, but now they are used extremely rarely — mainly in devices where the dimensions of the case initially allow the installation of such power sources (a typical example is batons, see "Type").Cells of this type can be produced both in the form of disposable batteries and in the form of rechargeable batteries. At the same time, both of them can differ markedly in capacity; accordingly, the battery life of a flashlight with such a power supply will be different — depending on the brand of batteries (accumulators) used. Also note that this type of power supply — like other types of replaceable cells — is inevitably associated with additional expenses: you will either have to regularly buy fresh batteries, or spend money on a set of batteries with a charger.
