What Are the Different Types of Battery Voltage?


Quick Answer

Battery voltages typically range from 1.2 to 67.5 volts, depending on the size, configuration and number of cells included. Most moderate-sized, commonly available battery-powered consumer electronics use the low end of this scale, utilizing nickel cell cylindrical batteries. The Energizer number 416 battery comprises the upper end of the range, consisting of 45 zinc-manganese power cells.

Lead-acid car batteries, though considerably larger in size than many types of household batteries, commonly provide 12.6 volts of electricity. The large size of these batteries is necessary due to their continuously rechargeable design. The relatively moderate voltage output is due to a balance that maximizes the life of the unit.

Common noncylindrical batteries provide voltages ranging from 4.5 to 9 volts, depending on specific model. The capacity of these batteries, measured in milliampere-hours, varies as a function of the size, material and number of power cells. The widely used 9 volt battery, often found in smoke detectors and radios, has a current capacity of 120 milliampere-hours with a nickel-cadmium cell and a capacity of 1,200 milliampere-hours for a lithium core. A lithium-polymer 9 volt battery, rechargeable for a number of cycles, has a capacity of 500 milliampere-hours.

A 6 volt lantern battery has among the highest capacities of nonautomotive or marine batteries, typically between 10,500 and 26,000 milliampere-hours depending on cell material.
