The nine-volt battery, in its most common form was introduced for the early transistor radios. It has a rectangular prism shape with rounded edges and a polarized snap connector at the top. This type is commonly used in clocks and smoke detectors. They are also used as a backup power to keep the time in certain electronic clocks.This format is commonly available in primary carbon-zinc and alkaline chemistry, in primary lithium iron-disulfide.
Most nine-volt alkaline batteries are constructed of six individual cells enclosed in a moisture resistant wrapper. These cells are slightly smaller that AAA cells and can be used in their place for some devices, even though they are 3.5mm shorter. Duracell batteries provide long lasting dependable power and quality across a wide range of everyday appliances.
