Alkaline batteries — true friends in life
Usually when you purchase new batteries, we ask the seller one question: "did they keep?". While most of the cost even without that and just buying the first. However, the battery is the battery different. Different types of these compact sources of energy have different characteristics, their advantages and disadvantages. Separately want to talk about this idea of man as alkaline batteries.
They belong to alkaline. Closest to them on the characteristics of alkaline manganese and zinc-manganese carriers of energy.
To begin, consider the main advantages of this type of battery. Notable among them are:
- low cost
- in conditions of high current and low temperatures show much better than the Heavy Duty LeClanche or (batteries that use other types of electrolytes)
- common almost everywhere, are produced in large quantities
- retain the value of the impedance during the discharge.
Of course, there are also disadvantages: the high content of mercury and flowing curve of the charge. However, with proper maintenance, these disadvantages do not play a decisive role.
The use of alkaline electrolyte in such batteries offers the prospect of a significant increase in capacitance (for example, for batteries AA and AAA, it increased in two times). The lifetime alkalinovh the batteries depends on how often you use the appliance where it is installed, and how much energy is needed for normal operation. However, small and irregular loads, the alkaline battery is able to last for up to seven (!) years. That is, the lifetime of batteries of this type also significantly exceeds the same indicator of other disposable items.
Alkaline batteries largely win against a no less popular today mercury and lithium variants. The situation with mercury batteries it becomes clear even on their names. As you know, mercury is very dangerous to the human body. Rough handling such batteries can bring many problems to the user. With regard to lithium, they are by far safer than mercury. But there are some disadvantages: several benefits have to pay the exorbitant price. Always buy lithium batteries – not a cheap pleasure. Therefore, to solve everyday tasks most often used alkaline.
Alkaline batteries can be of different sizes, and you'll be able to find exactly what you need. There are several basic sizes of batteries:
- AA (standard "AA")
- AAA ("mizinchikov")
- D ("barrel").
Also in sale you can find alkaline batteries irregular forms, for example a push-button.
When you select the preference, of course, renowned manufacturers whose products are well known in the market and enjoys the trust of customers for many years.
