Mainly two things about laptop battery maintenance

Now, people increasingly use the laptop as a laptop, one of the main components of lithium batteries will also increase the problems. So how should make good use of laptop batteries to lithium? Mainly to take two things:

   (1)  An appropriate charge-discharge;

   (2) To minimize the discharge less than the load or discharge. While the Laptop battery is a consumable, lithium-ion is no exception. But nobody wants the durability of the battery, following the battery began to speak. Firstly, to explain who is limited to lithium-ion battery.

The general literature and the country on standard lithium ion lithium-ion batteries on said load current must be between 0.2C to 1C. This is expressed by the load capacity of the battery current, such as your battery is 4AH, then the 0.2C charge current is 0.2 × 4 = 0.8 A, which is the load current must be between 0 8 to 4A.

In general, the charging current to the extent permitted by the smaller the better, rechargeable lithium, ion VGP-BPS2B battery should be the beginning of a constant current charge to IBM R31, for example, the current is 2.8A or more equivalent to 0.7 ° C, is charging circuit to control their own and can not set ourselves.

Although such a charge indicator does not exceed the requirements of the standard, but not relatively significant, especially when the battery capacity decline for some time after the load current may be more than 1C. Now the length of time users load laptop have also become targets regardless of the manufacturers were forced to charge current set so high, so the first step is to reduce the current load.

Lithium-ion batteries is very precious, good circuit load control is required. With this method of pricing can reduce the load current to prolong battery life while using the notebook’s original charging circuit controls the charge current to achieve them is also relatively simple, just buy a sheet of power (that is, food in a sort of book, it is better to buy two, followed by the methods referred to another use, should be of good quality), and resistance can be, and note heads resistance should be greater, after all the above, there are about 2W of power Otherwise, it would be more resistant to heat, the best use of a constant resistance over me, this resistance wire resistance and temperature independent basis. However, the shortcomings of this approach is also very clear is that, while not charging the work with the laptop lighter load current problem is solved, and now pay problems. In fact, it is difficult, after all, the laptops are used at work, the discharge current varies with the serviceability, the method mentioned here is the limited capacity of the VGP-BPS2C battery is designed specifically for the restore operation.

To start the machine, within the parameters of power management will never go into standby mode (standby) and hibernation (hibernation), others are made more energy saving modes, including including processor speed, turn off hard disks, turn off the screen, so also in TP management process of closing some unused material, such as sound cards and so on, then open the status window battery display, and allowed to run in the foreground. Close other programs, including screen saver and other regular programs running. Do not use the machine, do not close the lid, let the battery discharge is completed (not to discharge the minimum value is set to 0 can be set at 3%). Display and hard drive after closing the discharge current of approximately 0.5 A (IBM R31 can be performed on a minimum discharge current), the battery discharge to a minimum value determined after the machine s ‘automatically stops.

The discharge lasted about 4 hours, depending on the capacity of your battery may be different in different.

Finally stressed that the above method is not dead, and in particular, discharge, or 10 times what can be done once and elsewhere also

Battery does? Charge is best done with a low load current, of course, if the need to use the sony VGP-BPS2A battery directly to the power plug inserted into a laptop on it.

Several problems on the mobile phone battery

Mobile phone battery maintenance

Mobile phone battery is preferable to have two or more of rotation, each time you use must be fully charged and also run out before charging, the charger is also very particular about it is better assembled. Or buy a good quality. Better not use mobile phones during the lateral load, so the cell phone VGP-BPS2C battery, but pretty good. Is preferable to use mounting the battery, or use the Scud, Desai, and the battery to go to specialty stores or supermarkets to buy, guarantees to buy the real thing. A battery is best to reuse as much rest as possible.

Mobile phone battery How to Repair

1. If prolonged use of the universal rechargeable battery for mobile phones, so a result of Universal charge current is too small <80-150mA> affect the battery life to normal play, the normal load current 300 -800mA, recommended a week of continual use after the universal support using a direct charge or go home right filling with special charger to activate once great course, use more of the battery capacity of the normal room and prolong life.

2. Handset batteries for over 2 months does not use electricity shall be guilty of placing too long subject to current standard load and normal use of this cycle calls 2-3 times for best results.

3. If the use of batteries for mobile phone contacts Mobile battery found in the oxidation of the metal has rusted. Please forward to other things with alcohol or cleaning.

4. To bring the process to protect the device from the VGP-BPS10A battery, if installed in his pocket, or packed in their pockets because the pockets of metal and metal contact with the formation of a short - circuit the battery, the battery’s internal protection circuitry, a long time may damage the system battery circuit protection. Proposed to use special tools to protect the battery proceed to carry.

5. Acquisition of a new battery, first check the existing capacity is used, and then loads the normal use of electrical discharge saturated, cycle 3 to 4 times the battery can be delivered in a normal state, conducive to extend the life of Battery /

6. To buy a new battery when the battery sales the best place to get that measure voltage with a multimeter. The voltage is 3.6V above the normal. 3.6V below may be self-discharge is too large

7. The battery is best placed in the 15-25 degrees Celsius, the temperature setting is too high for too long causes the battery composed of fat drum, which seriously affects the battery life but also bring some risk factors.

8. Suggest that you never want to buy virtual capacity that exceeds the normal capacity of the standard battery capacity, which is a kind of irresponsible consumers. This is mainly used a number of low-quality batteries, has no intention of doing manufacturers long term battery, as only immediate, regardless of consumer safety and health. Suggest that you should not buy special VGP-BPS13 battery super-exaggerated capabilities.

Expansion of mobile phone battery

Batteries for a long time under normal circumstances would not be inflated due to the expansion of the battery charge time are too long causing the problem. It does not use, but the wait time is becoming shorter.

Battery heat expansion reasons:

When the power consumption in standby mode is very low, which means that it is the equivalent load resistance of the battery discharge current is very large so small it does not heat the battery, the battery of low internal friction.

Leaving aside a portion of battery power after the resistance increases, but the business needs of today’s mobile phones can be reduced, then much of the energy consumed in the battery internal resistance, which leads to mouth of the battery, accelerating the discharge, the acer-lcbtp03003-battery-p-16747.html”>LCBTP03003 battery thus quickly time use.

It is the prolonged use of mobile phone battery will cause fever.

Mobile phone battery fever hazards:

1. Mobile phone battery can cause prolonged fever heat parts inside the phone, making the new mobile startup or

Hang up the phone

2. Mobile phone battery heat will increase the long battery itself, the heat if it is sealed class (Nokia is not sealed, is mounted directly to the battery) battery will lead to the expansion spectacular air, causing the battery as the external process, the explosion from a severe case of the battery.

3. Mobile phone battery cell itself is a warm weather will accelerate the aging process and shorten its life.

This is the phone A1045 battery mobile phone and harm long-time heat.

Mobile phone battery to prevent fever and solutions:

1. Preventive measures:

Combined 1. In normal room temperature, the heat does not exceed 60 ℃ is a normal phenomenon, it will not damage the battery.

2. Using time high current charger should not be too long, too long to charge the battery will be damaged, but also generate heat.

3. Chargers preferable to use the reputation of origin or quality products.

4. If it is unwilling to use the words, it was suggested to the charger (trickle charge mode) load, and does not result in the heat of the battery.

5. Using the mobile phone to listen to MP3 or mobile phone battery charging time as feeling a little hot, you can use * # 0228 # to see the temperature exceeds 60 ℃, then immediately return to the standby or replacement of batteries to use, as in the charge, then immediately take part in the charger.

2. The solution:

1. If the handset battery has been charging the battery together, it would also have a solution. Is to use your fingers to find the battery first, the gap (near the cell phone charger for mobile phone batteries on the back electrode, by going to a place little soft), with a response drill a hole, so that the air inside ran on the list.

2. In addition to purchasing a battery.

What is fuel battery?

Fuel battery is a device used to generate electricity in order to understand the value, look at each combustible “and” batteries “that the two words.

To use coal or petroleum fuels to produce electricity, you have to burn coal or oil. They burn energy can be produced when water is heated by turning it into steam generator steam turbine can be used to rotate in a magnetic field. This produces a current. In other words, we are the chemical energy of fuel into heat, then heat energy is converted into electrical energy.

In this process of double conversion, fuel much of the chemical energy of lost origin, however, is very cheap, even if such a waste, does not prevent us from producing large quantities of electricity without the need for costly .

Also possible to directly convert chemical energy into electrical energy without first converted into heat energy. To this end, we use the Laptop battery. This battery consists of one or more chemical solutions, including the two rods of metal insert electrodes. Each electrode carried out specific chemical reactions, electronics are not released is being absorbed. An electrode to another electrode potential than the large, so if the two electrodes connected by a wire, electronic go through the wire from one electrode to another electrode.

This flow of electrons is the current, as long as the chemical reactions of the battery, this current will continue. Battery flashlight is an example of such a battery.

In some cases, when the battery runs low, forcing people to back current into the VGP-BPS2C battery, it will, in turn, in a chemical reaction, therefore, the battery can be chemical energy stored and used to produce electricity again. Car battery is an example of such a battery is reversible.

In a battery, the waste of chemical energy is much less because it will only be a step of chemical energy into electrical energy. However, the chemical battery is very expensive. The zinc used to make batteries flashlight. If you try to use enough zinc or similar metal to serve the whole city ready to energy, the cost of a day, it would take billions of dollars.

Fuel batteries are a kind of concept of fuel and batteries combine the two devices. This is a battery, but without using expensive metals, but only the least expensive fuel to produce chemical reactions. Of these fuels through a chemical energy into electrical energy becomes the stage than the usual two-step approach is much less loss of energy. Therefore, you can provide humanity with the power on the greatly increased.

The problem is difficult to prepare a really reliable way to work in fuel batteries. A product such a battery, which is based on a combination of hydrogen and oxygen to produce electricity, but hydrogen is still very expensive. Some people with carbon monoxide instead of hydrogen is much cheaper. Recently prepared using a combination of water and oxygen under the influence of bacterial activity in the battery that generates electricity. Without doubt, the idea of wastewater into electricity is encouraging, and can solve two problems: making energy and waste disposal.

In the fuel Dell RN873 battery can be useful indeed, before there is much work to do, but they represent a good future.

How to identify the quality of laptop battery

Laptop battery currently on the market varies greatly, a large number of low-quality products into the market, including many counterfeit original battery, these bring great risks to consumers. For non-professional consumers, we propose several ways to select a new battery according to the following Laptop battery:

1. Check the package

a.There should be a brand. Neutral non-branded packaging products easily lead to buy inferior products or second-hand refurbished products.

b.There should be a sealed anti-static bag, anti-static sponge, etc, these are the basic configuration to protect laptop Dell U4873 battery.

c.Should have a bar code. Barcode is authority of identity unified management standard recognized by the country.

2. Check the appearance

a.There should be no scratches or obsolete sense, or it may be second-hand refurbished goods.

b.There should be clear parameters, performance, application of model identification.

c.There should be no opened spoor on hp PB992A battery cover seams.

3. Check there is a formal guarantee notes and after-sales commitment

Qualified cylindrical batteries used for formal professional notebook battery products, from the date of the factory, will be guaranteed one-year warranty. If there has no such commitment, then its use of batteries and other materials are likely unqualified batteries, the secondary batteries. Currently on the market appeared with the proliferation of laptop batteries converted by waste batteries of Japan, Korea, and inferior VGP-BPS2C batteries, this seemingly cheap products are actually a profiteering products and devastating to the normal use of the notebook computer, and may also a serious explosion causing bodily harm to consumers.

Why do poor-quality laptop battery explosion

There are many factors cause the poor-quality laptop Li-ion battery explosion, but the principle is because of batteries produce large amounts of heat caused high temperature and high pressure which lead the Laptop battery to fire and explosion. Common reason of the explosion caused by the following categories:

1. Heating caused batteries decomposition, combustion, and explosion. The explosion temperature varies due to the battery components, such as batteries with LiCoO4 ingredients heated to 165 ℃ 45 minutes may explode (belonging to more heat-resistant). Although usually it’s difficult to put the Dell FK890 battery heated to such temperatures, but usually in use still have to be careful not to put the battery in a place near heat sources, such as a closed car under the sun exposure and close to the engine, do not close to the fire source either. 

2. Overcharge caused the explosion. If charge the battery with an unqualified charger, while the battery protection chip failure, when the charging voltage exceeds 4.5V, if the negative electrode capacity of poor Lithium, lithium-ion batteries will be deposited to make internal short-circuit; if negative Lithium capacity is relatively strong, then the solvent is rapidly oxidized to produce a lot of heat so that the hp PB994A battery temperature get higher and lead to more reactions and emit more heat. If the charging current is large, and the stability of the batteries is also very poor, batteries temperature rise rapidly, the battery will be fire, explosion. So, the friends who buy some cheap, non brand lithium batteries had better pay attention, you can ensure that your battery protection chip works? When the VGP-BPS2C battery charge, and if you feel unusual heat you should decisively handle that.
