AA batteries (R6) - fingers are different
Cheap AA batteries , with prices starting from a few dozen groszy each, are most often ordinary zinc-carbon batteries . R6 batteries have a relatively low capacity and are suitable for low-power devices. Low capacity directly translates into short operation time of powered devices. Typical examples of such applications are clocks and alarm clocks (mechanical or with LCD screens) and remote controls.
Alkaline batteries - the most important information
In the case of devices with a current consumption of several hundred milliamps, alkaline sticks will be a much better choice. Products of this type are characterized not only by a much higher capacity, but also by a longer shelf life. For this reason, if we sometimes forget to replace the batteries, it is better to use alkaline batteries which, despite their higher price, will last longer in devices with lower power consumption. In the case of toys powered by electric motors, flashlights or some cameras and radios, the only right choice will be LR6 batteries, an alkaline version of AA batteries.
R6 AA battery - Parameters worth remembering
Most users know the nominal voltage of AA batteries, which is 1.5V. A much smaller percentage of us usually remember about other, equally important parameters. For example, not all batteries are able to operate within a wide enough temperature range. If we are photography enthusiasts and use a camera or accessories (e.g. external flash) that are powered by R6 batteries, it is worth purchasing good alkaline batteries, e.g. from the Duracell Industrial series.
AA batteries - Batteries for professionals
The Duracell Industrial series sticks are perfect for ambient temperatures ranging from -20oC to +54oC, a range that exceeds the operating capabilities of many cameras. Low internal impedance at a frequency of 1 kHz predisposes the batteries to work in applications with high current consumption (also impulse). Please remember that using any type of battery in conditions that exceed the manufacturer's specifications may result not only in limited life and efficiency of the power source, but also with the risk of battery damage. Our store also offers AAA batteries packed in, among others: 4 pieces each, lithium batteries (pills), Li-Pol batteries and many others.
