Several ways to charge the laptop battery

In our time, no one is surprised by various mobile electronics. And laptops have spread for a long time and become satellites of many people. If you go out into the street, you will definitely get a person with a laptop in a cafe, park, metro, etc. Some use a laptop for entertainment, others use it to learn news and do the work. Many take a laptop to work, on vacation, business trip. The main advantage of the laptop is its mobility. It is provided by the laptop battery. To take the laptop with you, you need to charge the battery. And you need to do the charging correctly. In this article we will talk about correctly charging  laptop, as well as how to charge the battery without a regular charger.

In all modern laptops, there are either rechargeable batteries. They have long pushed back alkaline batteries like Ni-Cd and Ni-MH.

• High energy intensity;
• Low self-discharge;
• Absence of harmful substances in production;
• There is no memory effect;
• Compact size.

Thanks to these advantages, lithium batteries have become dominant in consumer electronics, as well as in some portable instruments. True, most of the mobile power tool still works on alkaline batteries. Lithium can not replace them, because they are not able to provide a high discharge current.

Laptops use batteries consisting of cylindrical battery cells. You can see them in the image below.

The average lifetime of the lithium battery is 400-500 cycles of charge. By the time this is 3 to 4 years. To ensure that the battery has fully worked its life, you need to comply with a number of requirements for charging it. So today we will understand how to properly charge the laptop battery.

How to properly charge the laptop battery?

The correct way to charge the battery, as you already guessed, is simply to connect it to the network through a standard power adapter. In the operating system Windows, which runs most laptops, it is possible to control the degree of battery charge. You can also set the power-saving mode and the battery discharge limit, at which the laptop will shut down. These settings can be made in the "Control Panel" -\u003e "Power Supply".

  In the system tray there is a battery icon. Clicking on it, you can always see the battery level of the laptop and information about its operation (from the network or offline). As for the level of charge, for lithium batteries it is better to maintain it in the interval of 50-80%. This ensures the longest battery life. It is clear that it is impossible to maintain such a level of charge continuously. But the rules set out below, to implement quite realistically:

• Do not discharge the battery before turning off the laptop. If you see that the indicator in the operating system shows less than 50%, connect the laptop to the network;
• Also, you do not need to constantly keep a laptop with battery connected to the network. If you often work at home from the outlet, remove the battery and store it separately. Do not forget to charge it by about 50-60%;
• Periodically (every 3 to 4 months), do a battery calibration of the laptop. This is a full charge of the laptop battery and its subsequent discharge. This cycle is performed 2-3 times. If there is no time to perform this procedure manually, you can use.

And one more tip, which does not apply to charging, but is very important. Do not overheat the battery. If you load your laptop with high-capacity applications and it gets very hot, buy a cooling pad for it. Otherwise, the heat inside the housing, allocated by the components, will heat the battery. This is highly undesirable for lithium batteries.

How to properly charge the laptop battery without a charger?

There are situations when you need to charge the laptop battery, but with you there is no charger or you are away from electrical networks. Below are described several ways to charge a laptop battery without a charger.

Charging the laptop battery in the car

This option to charge the laptop battery is suitable for those who spend a lot of time in the car. The car does not have an outlet and a generator in on-board network  generates no more than 14 volts. But the situation can easily be corrected by buying a portable inverter.

These devices are made for cigarette lighter convert the voltage into several options at the output. Ideally, take an inverter that can provide an output voltage of 20 volts (most common laptops have a 19-volt battery rating). There are inverters at 110 and 220 volts. It is better to take the device with an output under the power connector of the laptop. If you charge via USB, then due to the limitations of this current interface, the charging will be greatly stretched in time.

The disadvantages are also the fact that you can charge the laptop battery through the inverter only on a running engine. That is, the option is ideal for charging in transit.

Instructions

Check if your phone model supports charging via USB. To do this, go to the manufacturer's website and familiarize yourself with the characteristics of your mobile. For example, if you have phone Samsung, go to the website http://www.samsung.com/ua_ru/consumer/mobile-phones/mobile-phones/index.idx?pagetype=type_p2&. Most Nokia models do not support this feature, but some models are an exception. List of models with this feature: 3710 fold, 5630 XpressMusic, 6500 classic, 7900 Crystal Prism, 7900 Prism, 8600 Luna, 8800 Arte, 8800 Carbon Arte, 8800 Gold Arte, 8800 Sapphire Arte, E72, E75, N85, N900 , N97, N97 mini, X3.

Connect the phone with a cable to the USB port of your laptop. On the phone, select the connection mode, for example, "Media Transfer" or "Storage". Next on the screen laptop  select the phone and open the explorer window. Look at the mobile screen and determine by the status of the charge indicator, whether your phone has started charging. Wait until the phone is charging from the USB and disconnect the cable.

Use an extra battery for your laptop if you often have to charge your phone from laptop, for example, in a train, car. For example, connect APC Universal Notebook Battery to it. This is a universal battery that is suitable for all laptops. It is an alternative option for extending the operating time of the equipment for several hours, weighs this device 750 grams.

Note when charging your phone from laptop, that the Usb-connector is capable of providing only 500 mA charging current, while the usual network charger  feeds the phone with a current of about 800 mA. Therefore, the time of charging the phone from the computer will be more than from the outlet.

The laptop, first, is compact, and by functionality it can replace a stationary computer. Secondly, you can take it with you and work where you want. But in order for a laptop, disconnected from the network, to work for a long time, it is necessary that he had a good battery.

You will need

• Laptop with battery
• Electrical network

Instructions

note

Pay attention to a few nuances. If you do not use the battery for more than two weeks, it may be damaged. This is due to the process of loss of capacity in the battery. Therefore, take the rule of "preventive" charging of laptop batteries.

Helpful advice

If you work on a laptop often and continuously, purchase two batteries. While one will sit down, the second will be charged, which will allow you not to be nervous because the battery is discharged inappropriately, and there is nothing to replace it with. In this case, you will definitely need a stationary charger.

Sometimes there is a situation where phone  it is necessary to urgently charge, but there is no suitable charger nearby. How to act in this case? The answer to this question will help to give numerous folk tricks.

Instructions

The simplest solution is to charge phone  from the computer, but this is only possible if you have a USB cable and an on-board computer at hand. Charging will take longer than usual, but phone  can be charged at full power.

Use a universal charger, popularly called a "frog". Pull out the battery battery  and connect it to the appropriate places on the "frog". The most important thing is not to mix up the contacts: positive to positive, and negative to negative. Then insert the charger into the outlet and watch the indicators. Of course, the "frog" is not always there, but it will save you from having to look for a charger from your model phonea.

If you have a charger, but it is not suitable for your phonebut, you can solve the problem as follows. Cut off an unsuitable part of the charger with a knife or sharp scissors and cut the insulation cord along. Then peel them from the insulation for 1-2 cm. Take out phonebut the battery, connect the blue (black) wires to the contact with the "+" sign, and the red (white) to the contact with the "-" sign. Insert the charger into the wall outlet.

If you are in a place where there is no electricity at all, for example, in the forest, you can use a flashlight-expander that charges not from the battery, but from the generator. Such accommodation is popular with tourists. You will need such a flashlight and a piece of wire from the charger with a suitable connector. Disassemble the flashlight, peel the wire harness from the insulation and attach it to the flashlight generator, observing the polarity. Rotating the mini-generator knob, you can fully charge phone.

Today, the laptop is a great replacement for a cumbersome personal computer. Mobile device, equipped with a battery, can be used where there is no network. True, his charge is enough, as a rule, for one and a half to two hours. Then it is necessary to charge. But what if the outlet or charger is not around, but work on a laptop right now? In such cases, users are interested in how to charge a laptop, for example, through a laptop, and what alternative methods exist.

Can I charge my laptop through a laptop?

Unfortunately, laptops with all their advantages are considered to be a gentle technique that requires special treatment. So, for example, for each model of the laptop you need to use only your own, suitable charger. It converts the voltage from the network by the amount that this laptop requires, protecting it from failure. As a result, you will not be able to use the charger from another model. At the same time, many users are interested in whether it is possible to charge the laptop via USB from another PC. In general, this interface performs many functions, including data transfer or backlighting. But the charge for the laptop battery that can pass through the USB connector will not be enough. Although conventional phones, smartphones and tablets are easily charged when connected to a PC via a USB port. But judge for yourself - the port is able to miss the power of only 4.5 watts, and the laptop requires at least 30 watts.

Among the owners of portable PCs there are also those who are in search of information on how to charge the laptop via Wi-Fi. In fact, it is absolutely impossible to realize in reality. The fact is that Wi-Fi is a technology of connecting to the Internet   on a wireless basis due to radio signals. As you can see, there is no transfer of a charge of speech.

Similarly, without harm to the battery, it will not be possible to charge the battery from the laptop without the PC itself. The only option is to charge the battery through the laptop, and the absolute same model. It is inserted into the socket for the native battery.

In general, a great option for trips is the purchase of an external battery. It is connected as soon as the built-in battery starts to "sit down". If on warm sunny days you prefer to spend time outdoors, in the park or in the garden, buy special solar panels  for a laptop.

A rechargeable battery is the weak point of any laptop. The way it gets older, the faster the battery sits. Therefore, the issue of recharging it gets sharper and sharper, and the charger is not always at hand. Is it possible to charge the laptop via a USB port from another computer or from an external PowerBank battery? Let's try to understand this issue.

If I was asked this question several years ago, I would say with confidence that no, you can not! Indeed, before the USB port on the laptop was used exclusively for connecting peripherals. Yes, it was possible to recharge the phone or tablet, but he had no reverse action. A special power supply was used to charge the battery. Moreover, often each manufacturer had it with its own, individual connector, which was terribly inconvenient. Especially on the road.

But time flows and everything changes. On the latest models of laptops, netbooks and ultrabukov for power supply began to use a new USB 3.1 port. This is the so-called Type C connector. This is how it looks:

So thanks to technical progress, you can finally use the USB ports to charge the laptop.

What are the differences between ports

The fact that the USB standard itself has been developed quite a long time ago, back in 1994. And then the question of supplying pure food through this bus was not at all. In the future, that for more than 20 years, it was thought up quite a lot of types of connectors YUSB:

But only all of them were united by the fact that they could not provide transmission of power more than 4.5 watts. If for a smartphone or tablet this is at least enough, then for a laptop you need at least 30, and preferably 50 and above. Accordingly, charging the laptop via USB and speech could not be until the appearance of a more energy-intensive version. And it became Type C. In size, it is almost two times less than the already familiar 2.0 / 3.0 port:

But it is quite possible to provide a current transmission of up to 100 watts in both directions - that is, both to connected devices and from them to the host. This is enough not only for conventional models, but even for gaming laptops. You can take one or two powerful pour-pots along with you on the road and do not worry about the fact that there may not be an outlet at hand!

And what about the owners of old models?

Unfortunately, they will not be able to charge the laptop via USB-port under any circumstances. They just do not know how. How to be in this case? Just buy an extra battery and carry it with you. Well, or, as an option, save money to buy a new mobile computer. You can argue that you can not afford to pay any money! But if your work depends on it, then it can make sense to invest? You decide! Good luck!
