When there are two or more competing companies on the battery market, the consumer naturally asks about their advantages and disadvantages. From this article, it will be possible to obtain detailed characteristics and indicators of the two companies and find out the answer to the question of which batteries are better - Duracell or Energizer.
Batteries: what are they?
We turn on the TV without hesitation, find out the time from a working wall clock, use a desktop calculator, and for us it comes naturally. But these devices work with the help of small elements, the existence of which greatly facilitates life and saves our time.
And, of course, talk about the battery. It is a power source that generates electricity. And this happens under the influence of an ongoing chemical process. The principle of operation is based on the use of a chemical reaction of twometals (possibly - their oxides) in the electrolyte with the simultaneous occurrence of an electromotive force. Since such reactions are irreversible, they are called "primary".
Types of batteries
Marking of chemical power sources occurs in accordance with the composition of the electrolyte and the active metal used in their device. According to this parameter, there are five types of round (cylindrical) batteries, but two can be considered as the most common and frequently used:
1. S alt. Produced from inactive carbon. The peculiarity lies in the fact that when a break in activity is made, the batteries are recreated. This helps prolong battery life.
2. Alkaline (alkaline). Here, an alkaline electrolyte acts as a chemical element. This type of battery can be stored for a very long time. During use, the voltage on the electrodes changes to a much lesser extent than with s alt.
Battery types
In everyday life, when you have to choose batteries, confusion often arises, and the question is often whether AAA batteries are finger or little fingers? To clarify this point, let's look at the difference between them:
- Type AA (finger type) - AA standard products have a diameter of 13 - 15 mm and a length of 60 mm. This type of galvanic battery is very common all over the world.
- Type AAA (little finger) - these batteries have such dimensions as: length44.6 mm, and the diameter is up to 10.5 mm. The weight is approximately 12 g and the voltage is 1.5 V. This type is used in various small-sized electronic devices that consume a small amount of current (all kinds of remote controls, portable audio players, cameras).
Having got acquainted with the main types of power sources, let's move on to the main topic of this article. To find out which batteries are better - Duracell or Energizer, you should talk about these competing companies and their products.
Energizer batteries, specifications
One of the most famous companies in the field of creating batteries - "Energizer". The logo of this company is known all over the world. The manufactured products are divided into the following groups: Ultimate Lithium, Maximum, Plus and Alkaline.
Alkaline batteries work stably at low temperatures, have high charge capacity. They also have a very low degree of leakage and a long storage time. Plus class features is an innovative PowerSeal technology, characterized by the fact that it retains a charge up to 10 years. This long period allows you to be sure of the reliability of the source used.
Maximum batteries are engineered with PowerBoost technology and are characterized as the longest lasting Energizer alkaline battery range, lasting up to 70% longer. Available in all five sizes.
Batteries"Durasel": characteristics
The American company "Duracel" in many respects received the title of world leader in the production of high-quality batteries and accumulators. Mercury sources acted as the initial batteries produced by it. They were more often used in military affairs. In the future, the company "Duracel" regularly created batteries using innovative technologies, which were to a large extent ahead of competitors in terms of their performance.
Duracel holds about one-fourth of the market in this area, but their popularity has declined over time due to the increasing proliferation of competitor rechargeable devices. This company produces three main classes of alkaline batteries (alkaline): Basic, Professional and Turbo Max.
Comparison of Duracel and Energizer batteries at the price
If we talk about the pricing policy of these firms, they are in the same segment - "above average". The high cost of the products of these firms is due to certain points, such as:
1. The manufacturer itself. Yes, we are forced to pay for well-known brands with a long and high-profile history. And this applies not only to shoes, clothes and jewelry, but also to batteries.
2. High quality materials used to manufacture products. This is undeniable, both firms do not skimp, and apply the mostmodern technology using the highest quality materials.
So, the average cost per item is:
- Battery "Energizer", AA (LR3) - 40-50 rubles.
- Battery "Durasel", AA (LR3) - 60-65 rubles.
- Battery "Energizer", AAA (LR6) - 40-50 rubles.
- Battery "Durasel", AAA (LR6) - 60-65 rubles.
As you can see, the price of Duracell batteries is higher. And we have to find out how justified it is.
Comparison of batteries by technical specifications
After examining all the tests that have been carried out on the power supplies of these companies, it can be noted that a high price does not necessarily mean high quality. Which batteries are better, Duracell or Energizer, cannot be answered without considering them according to their technical characteristics.
For a fair assessment, it is necessary to evaluate the operation of batteries of the same type from both companies. This will be the most common type - alkaline, type AA.
- The first metric to evaluate is how quickly batteries drain when they are continuously discharged. For greater clarity, we can cite as an example the work of a powerful player or a radio-controlled tank. In this test, both companies show far from the best results compared to batteries of a cheaper price category: Duracel - 0.72 hours, Energizer - 0.64 hours.
- The second indicator for evaluation is how quickly the batteries run out when a powerful, but short-term (impulse) occursdischarge. This is an imitation of the work of any gadgets that are characterized by such discharge, for example, a digital camera with a flash. In this test, the undoubted leader is the Duracel battery, which worked in this mode for 4.72 hours. "Energizer", as in the first test, showed itself not from the best side - 3.58 hours of work.
Reviews and Conclusion
So, which batteries are better - "Durasel" or "Energizer"? As you know, the opinion of people is mostly subjective due to the fact that it is based solely on personal experience. And this experience may turn out to be sad only because, for example, a person came across an initially defective product. Therefore, blindly trusting reviews when choosing batteries is not worth it. But after reading what people write on the most famous review sites, one thing can be argued - there are fewer disappointments with the operation of Duracel batteries than with Energizer power supplies. None of those who left a review denies the fact that the price of Duracell products is high, but most tend to believe that it is justified.
As for the practical experiments and tests carried out on batteries, there are also many points that do not allow for a 100% correct assessment. After all, it is impossible to test and compare all power supply options from the entire line represented by both companies. The average test score for a single battery may not look very competitive. But this does not exclude the fact that in the same series of batteries of the same company there is a type that will work much more efficiently.
