In no way demonstrates the ending charging and does not make it clear how much it remains until its end. The time for charging varies depending on the novelty and the type of battery, and if you charge the battery for too long, he simply can spoil. In this sense, pulse chargers that have an indicator or timer, which are a charge limiter are much more convenient.
Pulse devices also have drawbacks - for example, a chargeless non-discharged battery, you risk recharging it and contribute to a decrease in battery life and its performance.
Also there are charging on the microprocessor control with the prevention of random recharge, but, despite their high reliability, there are practically no such chargers for cellular such charger. In addition, such chargers are very expensive and are not suitable for all types of batteries.
Purchase the charger corresponding to the power specified in the characteristics, the power required to charge your phone. Also, the charger connector must approach the phone to the phone to prevent damage to the machine.
If the use of several types of batteries are in use, for example, "Misinchiki" and "Finger", it is worth stopping their choice on combined charger.
In the case when it is often necessary to recharge not until the end of the batteries, it is better to purchase a device with the function of the full discharge of the battery before it is charging. In this case, the discharge process lasts only a few minutes, and you can monitor it on a liquid crystal screen that such a device is equipped. Thanks to this function, the battery life is extended. Such a charging model will suit the owners of energy-intensive cameras.
The price of charging devices largely depends on the charge rate and additional functions, such as liquid crystalline indicators, automatic shutdown and others.

You can charge only rechargeable batteries. They are usually indicated 1,2A.

Charger device For a car is a universal and useful thing for workshop or garage. With it, you can not only charge the battery, but also start the car. Each of the charging devices has its own shape and size. For example, small and light memory (charging devices) are perfect for unexpected situations when the battery sat down and need to be quickly charged to the very end. But there are very large sizes, which are located on wheels and used in technical and workshops.
Instruction
The variety of batteries is great, but the chargers for them are not suitable for all types. Therefore, it is necessary to accurately determine the type of battery, whether it is a dried or bombarded, maintenance-free or serviced, helium-chipped or lead-acid battery with a valve control.
After that, it is recommended to see the electrical volume of the battery, which characterizes the current size given by the battery for a while. Depending on this, the criteria must be selected with a certain power. For example, for an empty battery for 50 ammers, a memory of 10 amps is suitable. And in six hours of charging, a fully charged battery is obtained. This zoom charges completely battery per 100 ammers in 11 hours. For such calculations, it is necessary to simply divide the battery capacity to the power of the memory and add 10% to the result. The output is simple: For the speed of charging, it is recommended to use more powerful memory.
Now you should choose a convenient type of work: from the cigarette lighter, from the network or from the solar battery. In addition to the convenience, when choosing should consider that solar batteries can be carried with them and do not need to connect anywhere, which will exclude emergency situations, but they are slower than charge; Zray from the cigarette lighter is quickly charged, some even have regulators, but at the same time they can recharge the battery, so they need strict control during charging; A network memory is easy to use and easy to handle, the only thing that is needed to have electricity to connect to hand and the outlet.
From the newest types of memory for a car battery, you can view chargers with a chip that allows you to control the charging and even test the battery to the recharging level. Its special indicator is very convenient in such cases.
note
It should be remembered that the car memory may harm the battery if it is incorrectly used, so it is necessary to carefully study not only the characteristics of the battery, but also the instructions for the charger. It is not recommended to charge the battery in the premises without ventilation and next to the items that are afraid of acid. It is also necessary to monitor the life and shelf life of the battery, since wear models allocate malicious pairs and proceed.
The battery of the smartphone or tablet always sits down in time, and not in all cases there is a socket to charge the gadget. For such situations, there are portable chargers with which you can charge the battery anywhere. What do they differ from each other, and how to choose a portable charger?
Instruction
The most important technical characteristic for the portable charger (it is also called PowerBank) is its capacity. It is measured in milliamme aperture, and what they are more, the better. If, let's say, you use this smartphone charging device, it is desirable that the container of the portable battery was more capacitance of your gadget's own battery in two or three times. This will allow twice or three times fully charge the mobile phone again, which is especially convenient on the trip.
True, the greater the container of the portable charger, the more it weighs and occupies the place. So, if this moment is important for you, look for a balance between compactness and the number of milliamper-hours. For some devices, such as MP3 player or wireless headphones, too capable external battery may not be needed.
Charging speed can also be different, it depends on the strength of the current. Find out how much ampere is needed to charge your device and do not forget about this indicator when you choose a portable charger. For most modern smartphones that support the Quick Charge function, the current is 1 a or even 2 A, and if they charge them from the source with a current power of 0.5 A, a lot of time will go.
The number of connectors on the portable charger may also have a value. Suddenly you want to connect two gadgets at the same time, or even three!
Some portable chargers have a solar panel that allows them to replenish the energy reserve away from the outlet. This is an additional plus of such a device. However, you should not feed the illusions: the solar battery is not able to charge it quickly. If you are resting somewhere in nature and decide to take advantage of the opportunity to replenish the charge from sunlight, take care of this in advance and leave the memory for a long time in the light.
Also, the value when choosing may have the convenience of indoctors, the design of the body, the manufacturer and the availability of any additional features. For example, some models have built-in flash drives, lanterns, card readers.
The charger is an effective rescue tool for an experienced car owner, which allows you to reanimate the entry battery if necessary, and with it the car itself.
Instruction
Make a choice between conventional charging and more complex start-charging devices. The first of them serve solely in order to perform their nominal function - to charge the battery exhausted energy. The devices of the second type are also suitable for launching the car: this procedure requires a battery of large energy costs, so if it will be discharged, the car will not be able to start until the battery is filled to the required mark. A commissioning device reduces the waiting time, since it can be used to immediately start a car and get to the right place even with an almost empty battery.
