Advice 1: How to charge a magnet

The magnet eventually loses its properties. In addition, it can be demagnetized by heating. Of course, it is easier to buy a new magnet, but, if you cannot find the product the desired shape, you can try to charge it.
How to charge a magnet
You will need
  • - powerful magnet;
  • - low magnet;
  • - wire of PEV;
  • - thin copper conductor;
  • - fuse Meringue;
  • network 220;
  • the high - voltage battery or battery pack;
  • - capacitor.
Instruction
1
If you want to restore the magnet temporarily, place it near a powerful current permanent magnet, paying attention to polarity. Leave the design for a month or two, and then assess the state of charge of the products – you will see that it began to work better. Thus it is possible to magnetize any metal object, such as a screwdriver, but its properties will disappear pretty quickly.
2
If you want to charge the magnet more thoroughly, collect the installation from the coil and magnet. To do this, wind the reel in coils of 50-200 (its size must exceed the core sizes by 30-40%) of the copper wires and place inside the magnet. Note that between the wire and the magnet should be insulator – to-air, paper, duct tape or other material, not conductive current. If the magnet is already polarity, Orient it in the coil the right way, you can use an ordinary compass.
3
Take a capacitor with a capacity of at least 5000 UF and charge it from the mains. Then connect the terminals to the coil (via the switch) and press the button to discharge it. Formed inside field to charge the magnet. Instead of the capacitor you can use regular batteries or rechargeable batteries with a voltage of 5-12 volts.
4
To charge or restore the properties of the magnet, is made industrially, use voltage of 220 V. For this to wind through the insulating layer coil of copper wire, the size 400-600 turns.
5
Take the fuse with a maximum current of 1-1. 5 amperes, it can be a thin copper conductor with a thickness not exceeding 0,05 mm or the Bose fuse in a glass tube (it is more safe, as rasplava wire remains within the tube).
6
Take a normal network plug wires and connect consistently to the coil and fuse. Turn the unit to the network, the fuse will burn, but the electromagnetic field formed inside the coil will magnetize the metal.
7
Be very careful during the last way, as you will be working with deadly voltage. Remove from the room of women, children and animals, and themselves stay away from the installation, as sparks of hot metal flying from the fuse, can get into eyes and skin.

Advice 2: How to charge the capacitor

When you install the car audio system powerful, sometimes it is necessary to connect the capacitors of large capacity. Each time, after removing the car battery, procedure must be performed to charge the capacitor. Also charging is required for initial installation of the capacitor.
How to charge the capacitor
You will need
  • A constant current source (vehicle battery). Resistor, supplied with the condenser or a 12V light bulb if it is not.
  • Wires for connecting the capacitor of the same section, and wires for power connection.
Instruction
1
Make sure that:
terminal of the capacitor " + " connected to the power wire of the amplifier;
terminal of the capacitor " - " is connected not to the amplifier and to ground of the car.
2
Gently remove the audio fuse.
Disconnect the wire from the terminals of your capacitor is marked with "+"
Connect your power source to the network (we have a car battery).
Connect the supplied capacitor resistor one terminal to the capacitor terminal marked "+".
Repeat the above step, if you connect it through a 12V light bulb.
The other contact "-" connect to the power cord.
Repeat the above step, if you connect it through a 12V light bulb.
3
Reconnect the audio fuse.
Wait at least two minutes, after which the resistor is required to disconnect, and the wire feeding the capacitor, to connect to "+" terminal directly.
When connecting through a resistor, the charging time of a capacitor determine its technical documentation.
Note
Do not tighten the clamps very tight.
Do not use the condenser from mechanical damage.
Useful advice
When connected via the light bulb the charging process of the capacitor becomes more obvious.
While charging through the bulb, it should light. After the light gradually goes out, this will be the signal that the capacitor is fully charged.

Advice 3: How to charge a agm battery

The so-called gel batteries, referred to as AGM or VRLA are lead and method of charging a little different from the usual liquid electrolyte. But they are maloobsuzhdaemyj.
How to charge a agm battery
Instruction
1
Remember that gel lead accumulators require practically the same security measures when using, as usual. When charging they can release hydrogen, although the probability of this is small. So close to charging the battery (even if it is installed in, say, an uninterruptible power supply or a cash register) you can not smoke, use open flame, any source of sparks. In any case can not be dismantled AGM, to close their short. However, unlike conventional lead-acid batteries, they allow work in any position, not just vertical.
2
Because the capacity of gel battery is usually small, in any case, do not use for charging car chargers. They stabilize the charge current is too high.
3
The simplest method of charging the AGM battery is used as the charger of the UPS is designed for use battery with the same parameters as the one you are going to charge. Purchase a second-hand source, which is out of order its own battery. When de-energized and turned off the source, connect to it instead of the regular battery, the one that you want to charge with the correct polarity. Remember that in most such devices the charge circuit has a galvanic connection with the mains supply, so while charging do not touch any wires. The device itself will tell you when charging is complete.
4
When charging AGM battery from a source of constant current (not stable voltage!) use the same technique as for the conventional lead battery. First, keep the battery under a current equal to one tenth of its capacity, as long as the voltage on the pins is equal to 2.4 V in terms of one Bank (for example, if a six-pack - 14.4 V). Then reduce the current to one-twentieth of the capacity, and will hold him under the current two hours. If the capacity is expressed in milliampere hours of current after the conversion will be expressed in milliamperes, and if the capacity is expressed in ampere-hours amperes.
Note
Battery technology AGM (Absorbent Glass Mat). AGM batteries are made by new technology Absorbent Glass Mat, which is based upon the principle of nettechcity of the electrolyte. These batteries are efficient, vibration resistant, increasing cycles of charge/discharge and easy to install.
Useful advice
The AGM batteries. Bosch HighTec. Over the past ten years consumption of electricity in the car has increased significantly. AGM batteries have already confirmed their cyclic stability in the conditions of the original equipment: they can withstand up to 300 charge-discharge cycles, or three times more than conventional starter batteries.

Advice 4: How to charge your headset

For example, Nokia uses only two colors – green and red; the first to identify the full charge of the device, and the second to indicate a lack of energy to continue operation of the device.
2
Connect your headset to a power source, use the special charger that goes with it are usually included. If it is absent for any reason, purchase a new. You can also try to use the charger of your phone, but in this case, the best option would be to not only match the connector size, but also the name of the manufacturer. For example, produced at the moment, the Nokia phones have a thin connector for connecting the cable szu, which suitable for almost all Bluetooth headsets this manufacturer, at least, modern. The Apple wall charger is also suitable for headsets by default.
3
If you have a car, purchase a special charger for the phone and the headset, which will charge them from the battery, thus helping you to stay connected even away from your home or office.
4
In order to understand what the headset runs out of power, pay attention not only on indicators but also on the quality and overall audibility of the subscriber. Despite the fact that talking about the safe use of wireless devices, try to reduce the mobile calls to a minimum. While driving, always use hands-free in order to avoid the creation of an emergency on the road.
Note
Battery of the headset should last about all day with frequent calls and conversations.
Useful advice
Buy original Bluetooth headset.

Advice 5: How to charge the old battery

Advice 7: How to charge ordinary batteries

Is it possible to charge ordinary batteries, that they have served some time? The answer is simple: you can, and make it easy enough. However, some methods can be dangerous.
How to charge ordinary batteries
To recharge ordinary batteries, can be used as charger and handy tools. It is important to know how to do it correctly. There is an opinion: if batteries are good to knock on the wall, they will last another couple of hours. And indeed it is. But there are other interesting and proven ways.

The conventional methods of charging batteries at home



Charge batteries at home, in the following way. With batteries you need to remove the wrapper, and then in the body done a few holes. This can be done with an awl or a Gypsy with a needle. Prepared for charging the batteries fall in a pot of well-salted water. Then the pot is put on the gas, and the batteries boil for a short time. Then you need the batteries removed from the water, dry, wrap well with electrical tape. So, as a result of the process of the battery charged and ready for a new job.

It is also possible to charge ordinary batteries with an awl. So, awl is required to make two holes all elements of the supply near the graphite rod. The depth of the puncture should take about ¾ of the height of the batteries. In the hole you need to drop either water or a 10% solution of hydrochloric acid, either double vinegar. After the liquid dripped to the top, the holes are sealed well with a slice of rye bread or clay. Ordinary batteries charged so that can serve for some time.

The methods of charging ordinary batteries by using special devices



Today there is a special device (device), for example, Battery Wizard, which can fully charge ordinary batteries up to 10 times or more. Many people consider it quite a bargain, which will allow in the future to save a decent amount of money.

You can charge regular batteries using a special charger. Batteries should be placed in the device and put on charge. As soon as the batteries are a bit warmer, they must be immediately removed. If the battery overheats, becomes hot, the charger may come in unsuitability, fire, or the battery to explode. Try, warmed up the batteries or not, just by hand.

Of course, to resort to the assistant drugs and Amateur experiments possible, but very carefully and very rarely, if the situation requires it. It is best to use special devices to charge conventional batteries or buy new batteries.
