subject: An Aa Battery [print this page] An AA battery is a dry cell-type of battery and commonly used in portable electronic devices. AA batteries have found a wide application in consumer electronics and they also satisfy energy demands, which is what the consumer looks for. The standard operating voltage for standard non-rechargeable AA batteries is 1.5 volts and for rechargeable batteries is 1.2 volts. This is understood as rechargeable batteries are designed to last a life time. Since these batteries produce 1.5 volts they are designed for products with high energy requirements.
There are different types of AA batteries namely, LR6 (alkaline), R6 (carbon-zinc), KR157/51 (nickel-cadmium), HR6 (nickel-metal-hydride), and FR6 (lithium-iron-disulphide). Out of these the LR6 (alkaline), R6 (carbon-zinc) and FR6 (lithium-iron-disulphide) are standard non-rechargeable AA batteries or they are also known as dry cell batteries and the KR157/51 (nickel-cadmium) and HR6 (nickel-metal-hydride) are rechargeable AA batteries.
AA batteries are variedly used in Stampers toys which are battery-powered vehicles that ran on a single AA battery and featured all-wheel drive. They are driven by a single motor that turned both axles. It is used in penlight which is a small, pen-sized flashlight, usually containing two AA batteries or AAA batteries. A number of different designs are common in this. In some an incandescent light bulb has an integral lens that focuses the light, thus no reflector is built into the penlight. It is also used in a digital camera that runs on and consequently devours AA batteries, it is figured out very quickly that AA rechargeable batteries are they way to go. Thus, AA batteries are a good solution for power hungry devices.
