How to distinguish the battery from the battery: external difference, if there is no labeling

Often came to the store for batteries for some devices, we find ourselves at an impasse and can not understand that we face in the window. It's just a battery or is it rechargeable. Their external appearance, color, size - everything is almost the same. If you do not understand some of the subtleties, it is quite easy to buy instead of the high-quality battery useless battery, then try to charge it. And then your luck - if all goes well, it will simply no effect, and if not our day, even before the fire is not far.

Unlike external battery from a battery

The first thing that will help us in the identification of the battery and simple battery - it is their label. Or rather, not themselves, and the information that is available to them:

1. First of all, looking at the case notes -

   rechargeable or do not recharge. The first inscription says that this is a device for recharging, and therefore - this battery. The second inscription warns that we should not even try to charge it, as it is a normal battery. Sometimes you can find information mark - Alkaline, it is also a simple battery, only alkaline, having a greater resource capacity.
2. Apart from the above inscriptions, you can pay attention to the numbers on the abbreviation mAh - it is just means that before we see a not a simple battery, namely the battery, the figures indicated it capacity. In a conventional battery capacity value is not specified.

And this is the most simple battery.

As a rule, these characteristic differences are more than enough to recognize the battery. In addition, there are such power supplies slightly more than simple.

But in the case may not be the label, and indeed any were inscriptions. How to be in this case? Then come to the aid of good old tester. voltage indicators at simple batteries are 1.6 Volts, while the battery is not more than 1.2 volts.

How can I tell if there is no labeling

Very often it happens that the labels may be damaged, and wrought marking may be erased. It turns out that the battery is left completely without any kind was unmarked. In this case, only the meter can help out.

Rechargeable batteries are always an indication of the capacity. This indicator allows us to know how long you can use the battery and charge it, and what equipment you can use it. In addition, it should be taken into account and stress.

characterized by two values ​​for the battery:

• 1.2 volts;
• 3.7 volts.

In batteries such values ​​a bit more:

• 1.5 volts;
• 1.55 volts;
• 3 volts;
• 3.6 volts.

If we look at the last lines in the first and second group, we can see that they do not differ. The only difference is 0.1 volts. Because of this, the battery can be taken as a simple disposable batteries. The converse is also true.

Define "who is who" in this situation can help a normal voltmeter. But as the differences can be miserable, then it is useful to read and to indicate the device.

Differences between different types of batteries

Between types of batteries as there is a difference.

Lithium-ion batteries

This type, in comparison with other, more "advanced", as the unit of mass has more power than his "colleagues". Therefore, in the smaller sizes it can provide the same operation time. Additionally, the distinguishing feature is its lower rate of spontaneous discharge. And it says that it can be stored for longer and thus maintain a charge.

Additionally, you can charge it when you need it, even despite the fact that the previous charge has not yet been completely consumed. This does not in any way a negative impact on capacity. Such batteries are more environmentally friendly than other types of rechargeable batteries. All of this suggests a clear advantage over their other batteries, but they cost a lot more. Although the materials used in the manufacture of this type of battery, virtually no harm to the environment, it does not mean that you can throw them wherever and however you want.

Batteries based on nickel and metal hydride

This allows the battery when its weight to stock more energy than the same weight, but based on nickel and cadmium. Therefore, it will last longer, do not require any additional charge. "Native" it with NiCd option that to charge it needs to be put not earlier than will be fully expended the previous charge. But if suddenly overlooked and began to charge before the charge zeroed out, they will lose less of their capacity than analogue-based nickel and cadmium.

Too bad that the battery very quickly loses its charge even when not in use. Hence the need to fully charge them before you clean up on a shelf for storage. The applied in the production of battery materials are less harmful to the environment than nickel-cadmium analog materials. But less harmful - does not mean that you can throw them in the street. There are special receiving points for recycling.

Batteries based on nickel and cadmium

If you observe the rules of operation, the battery is capable of operating for quite some time. To charge to put it is necessary only after a complete discharge, if it does not comply, the tank volume is significantly reduced. This leads to the fact that in the future it will need to be charged more often.

Despite this drawback, this type of battery the most durable and reliable of all, especially if used in warm or cold weather. Is capable of providing very high power at a time when it is particularly necessary. Very quickly lose their charge during storage, therefore, is not the fact that leaving behind a charged battery, and returned in a few weeks, will be able to use it without charge. Battery Materials heavily pollute the environment, therefore, have become unusable battery should be sent to the points of acceptance, rather than disposed of in general trash.
