As a rule, when buying new batteries, we ask the seller the only question: “Do they last long?”. Although most often we manage even without this, but simply buy the first ones that come across. However, the battery is different. Different types of these compact energy sources have different characteristics, their own advantages and disadvantages. Separately, I would like to talk about such a human invention as alkaline batteries.

They are alkaline. The closest to them in terms of characteristics are alkali-manganese, as well as manganese-zinc energy carriers.

First, consider the main advantages of this type of battery. Among them, the following should be highlighted:

• 

  low cost;

• performs much better than Heavy Duty or LeClanche (batteries that use other types of electrolytes) in conditions of high current and low temperatures;
• spread almost everywhere, produced in large quantities;
• keep the impedance value when discharging.

Of course, there are also disadvantages: high mercury content and a sloping charge curve. However, with proper operation, these shortcomings do not play.crucial.

The use of an alkaline electrolyte in such batteries opens up prospects for a significant increase in electric capacity (for example, for AA and AAA batteries, it doubles). The life of an alkaline battery depends on how often you use the device, where it is installed, and how much power is needed for normal operation. However, with small and intermittent loads, an alkaline battery can last up to seven (!) Years. That is, the battery life of this type also significantly exceeds that of other disposable cells.

Alkaline batteries win in many ways against the background of mercury and lithium options that are no less popular today. The situation with mercury batteries becomes clear already by their very name. As you know, mercury is very dangerous for the human body. If handled carelessly, these batteries can bring a lot of problems to the user. As for lithium, they are certainly much safer than mercury. But even here there are drawbacks: for a few advantages, you have to pay an exorbitant price. Constantly buying lithium batteries is not a cheap pleasure. That is why alkaline ones are most often used to solve everyday problems.

Alkaline batteries can be of various sizes, and you can easily find exactly what you need. There are several main battery sizes:

• AA(standard "finger");
• AAA ("little finger");
• С ("keg");
• D ("barrel").

Alkaline batteries of non-standard shapes, such as push-button batteries, can also be found on sale.

When choosing, of course, preference is given to eminent manufacturers whose products are well known in the market and have been trusted by customers for many years.
