Laptop Battery Drop Vastly

This may often happen to your laptop computer, laptop battery charge drop very fast. If they are charged will fill and full very fast, then if we use the laptop just can stand for just 5 minutes. What happened on this laptop battery?

I have had my laptop for a year. I have it plugged in most of the time but generally let it completely cycle at least twice a week.

Now when I charge it to 100%, I unplug it and it instantly drops to around 70%. Does this mean that the battery is going bad?

If you have this similar problem like my own, its like the battery needs replacement. If you bought your laptop new, and it's only a "FEW" months old...that's way to early for the battery to be going bad. I'd try going to your laptop manufacturer's website and see if there's a recall on your specific battery. You'll need to take note of the battery's serial number so you can compare yours with any recall orders. Just to let you know, batteries aren't generally covered by the warranty unless it's deemed defective.

The problem actually will also happen to all laptop, but normally is not too fast. This can happen after your laptop age about 4 to 5 years, if you use your laptop and maintain in the right way. If you maintain in wrong way, your battery laptop will damage just in a few months. This indicate that your laptop battery has leakage so that they can’t keep the power anymore. See here about Battery Maintenance.

Solar Energy in Indonesia

Solar Energy in Indonesia still less to use, even Indonesian locate on the equator area. Solar energy can convert into electric energy using solar cells. Compare by solar energy that already use as the source energy in China, indonesia left behind, even this country is located in subtropical region  The simple scheme how to change solar energy into electric energy is as on the below flow diagram:

The world can not go on living by using all the fossil fuels that are currently available. In fact, years down the line they are simply not going to be available, which is why it is important to convert to solar energy systems.

The great thing about solar energy systems is that they offer people the chance to be self sufficient. A one off investment in solar technology means that the can utilize the energy that is produced by the sun; for ever! The great thing is that for they can instantly convert the energy from the sun and use the electricity that has been created to provide free power for their home.

Battery Maintenance Tips

In order for long battery life, whatever the brand it used to be supported with good treatments and charging (charge), to either wet or dry battery or Free Maintenance (MF) battery which are now widely used in new motors.

Dry battery have price quite expensive, it takes a special trick to getting long-lasting battery and not make trouble. And the easiest way to stun the battery does not come up short, after the motor is turned on with the current starter motor which absorbs up to 400~ 500 watts, good machines remain turned on for about 15 minutes.

Most importantly, if once the starter will not on, do not try to push the starter switch constantly. Released it until about 5 seconds, then squeeze again. Given pause 5 seconds so that the battery is stable first." And if already living, better get used road, instead of settling on the spot. At that time the stun has been used back to fill, "says Ajib Rosadi, the lecturer staff at the Polytechnic campus manufactur Astra (Polman).

Conversely, the battery is often used for the ignition but the motor is difficult to live or just turned on a moment. Stun available in battery will be reduced by watts that have been used. If you frequently do, do not be surprised if the battery even faster come up short and difficult to start the engine. If it were so, must immediately discharge not let worn out.

Special dry battery or MF, recharge with special tools. For dry battery charging system is very small and stable, amounting to 0.5 amperes. "I'll stun the battery can be full, it takes 5 to 8 hours depending on size of battery.

Make Laptop Battery Live Longer

Several tips to make your laptop battery can Stand longer:

• Turn off Wi-Fi and bluetooth. Use shortcut key to instantly disable wireless networking.
• Don't play games on computer, music or DVD movies. Multimedia activities drain laptop batteries.
• Disconnect all external device like card modems, firewire, USB devices and optical drives. Use notebook touchpad instead of an external mouse.
• Adjust screen brightness, dimming your display saves battery power.
• Tweek windows Power option. Choose laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes inactive.
• Decrease or mute laptop speaker volume
• turn off all scheduled task
• Turn off auto save features in Microsoft office and other applications
• Turn off or dissable built-in wireless card
• Program from CD or DVD can copied to hard drive and run from hard drive.

To make laptop battery can live longer, actually many factors affect the amount of time that a laptop battery can deliver can deliver power before it must be recharged.

• If you don't use laptop for extended periods of time, i.e. for a week or more, remove the battery pack from laptop.
• Don't put battery in high heat or freeze temperature. Don't put on your car in summer time. Hot battery can discharge very quickly, and cold ones can't create as much power.
• Make sure to plug a laptop charger adapter into a UPS and not directly into a power outlet or surge protector.
• If you have a nickel metal hydride battery, completely drain and recharge the battery once a month to maximize its capacity to hold a charge.
• Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.
• Leaving a battery in a laptop while using an electrical outlet for long periods of time will reduce the life cycle of the battery.

Use Dry Cell Battery

The different with wet cell, use dry cell more simple because we don't need to check the level of liquid like on wet battery because if the level too low make this battery will damage. This kind of battery is free of maintenance. If dry battery look like weak and or there is a leakage of electrolyte, it should be better if you change it with new one. The symptom of battery that already broken usually has difficulties to fill the electric again, so the battery can't start the engine motorcycle or your car.

Using this kind battery usually you have a guide book that show you and give an attention that your battery is free of maintenance and broken permanently if the strip of filling cover protector opened. So don't open this protector cover because your battery will damage because can't filled anymore.

Attention:
Batteries release hydrogen gas which can explode during normal operation. A spark or flame can cause the battery explosion with a large enough force to kill or injure you severely.Wear protective clothing and face shield, or leave the battery maintenance to an experienced mechanic.

Curving on a Rough Plane Road

A car can't curve on a slippery plane road (with zero friction). So clearly, what plays as the centripetal force that makes the car able to curve in friction, which is exerted by the road surface to the four tires of the car. You also learned that when curving, the car's tire are rotating (not slipping) so the friction is static friction.

Why can a car slip when moving too fast on a curving horizontal road? This is because the speed of the car exceeds the allowed limit to make the turn. The formula for the speed limit or maximum limit that is allowed to make a safe turn on a rough horizontal curving road can be derived as follows. The source of centripetal force is friction f_s so:

F_s = f_s ----> F_s = μ_sN = μ_smg

by definition, the formula for centripetal force is

Fμ_s = mv²_max /r

Dry Cell Anode and Cathode

Dry cell battery usually just can use once, after the cell have fully used then disposed and should be change with new one. But now there are rechargeable type that can be recharged several times for example 1000 recharge, after 1000 times charge usually can be charged again and should be changed with new one.

Battery have two poles, positive poles and negative poles. Positive poles or positive electrode is called as cathode and negative poles called as anode. In dry battery each pole contains different kind of metal. In alkaline battery, anode metal is made from manganese dioxide and the metal in the cathode in zinc. For anode and cathode in other batteries can be seen on the table below.

Inside the battery there is a separator to separate anode area and cathode area and there is an electrolyte. Negative electrons will go to cathode in short way but block by electrolyte substance. When we make a circuit to contact anode and cathode then electron will flow through this circuit and we can use this power.

Battery	Alkaline	Lithium	Heavy Duty	Nickel Cadmium	Nickel metal hydride
Anode	manganese  dioxide	manganese  dioxide	zinc	nickel	nickel
Cathode	zinc	lithium	carbon	cadmium	titanium

New Battery Source

Battery source become very importance after the fuel crises era, because no other energy source can supply our system if energy that come from mineral finished. After the tsunami that happen in Japan last day, every developed countries think more concentrated to other energy source beside of nuclear energy, because nuclear energy very dangerous to our neighborhood.

People more concentrate to green energy, that energy come from this nature but more friendly to our environment. Green energy that proposed by many country such as Solar Energy and Wind Energy. Even solar energy can keep by battery but this system still have waste battery that should be disposed. Solar energy system usually use battery charge to make other equipment can running every time, either in night and day. Actually green energy concept is more concern to energy that don't have any waste into the environment, but solar energy have lessen much of energy waste from their system.

For those concept, china have build the biggest solar energy source in the world. Because China develop their industry but don't have any fuel source from their land.Except for coal, China has no other natural resources are able to meet its energy needs. Energy supplies and natural resources are relatively limited compared to the population in this country.

Wireless Battery

Toyota will improve their technology to develop wireless car battery. Collaboration with WiTricity Corporation, the company of Massachusetts, US, to realize this innovation of wireless battery charge system. WiTricity is the company that expert on the resonance wireless battery charging.

As Toyota mention, WiTricity system use without contact have more efficient and more practice compare with induction system electromagnetic, other wireless technology still use contactor and use in phone cell and other battery charger. Add by filling system of this wireless WiTricity is suitable for car. This system is more practice because can use when park and can be install in garage or other parking place.

Toyota decision is use technology base on Toyota Global Vision, to unite car, home and information. Wireless charge system only one of several technology that want by Toyota to facing the future technology, to make more technology electric car hybrid production.

Battery Charge

Currently many battery type on this world, and the most lately battery model is battery recharge. This battery can use several time but just can use until the battery recharge can store the force. After the lifetime of this battery is gone than you must change the battery with the new one.

The diagram of battery charger to fill the battery can be seen on the diagram below:

On the car system this charger have available and the reliability of this battery charger depend on the car technology use. Normally car battery charger is a simple electronic circuit which fill up the battery every time the circuit is turned on. If the battery is already full and the circuit not turned off, overcharge will be happened. Overcharge on battery is very dangerous because can explode because of hydrogen gas expel on the system. Overcharge can cause the electrolyte liquid evaporate and will broke the car components.

Overload Charged Battery Can Explode

On lead acid battery system they use an acid solution on their system. When this battery system is charged will produce hydrogen gas, the reaction of this chemical will written later on the below. If the rate of overcharge is small, the vents of each cell allow the dissipation of the gas. However, on severe overcharge or if ventilation is inadequate on the battery is faulty, a flammable concentration of hydrogen may remain in the cell or in the battery system. The properties of this hydrogen gas, if any spark can cause hydrogen explosion. Of course this explosion will make the battery damage and can make other dangerous expose because of the acid solution will spurt. Anyone that close to this explosion can injured by this acid.

The end of the battery will be severely swollen, and when accompanied by the case being too hot to touch, this usually indicates a malfunction on the charging system of the car. Other explosion that can happen may because of reversing or make short-circuit onto the battery, reversing of positive and negative leads will damage the battery and may to gassing and explosion.

The corrosion is caused by an imperfect seal between the plastic battery case and lead battery post allowing sulfuric acid to attack the battery post. The corrosion process is also expedited by over charging. Corrosion also can caused by factors such as, salt water, dirt, heat, and humidity in the air, a crack in the battery casing, or loose battery terminals. Inspection, cleaning and coating can prevent of corrosion on the battery terminal.

Battery Disposal Should be Process

Battery waste should be process in properly because waste battery contain of heavy metal and dangerous chemical that should be process first before disposed. The heavy metal contain on battery is depend on the kind of the battery use.

In the carbon-zinc battery after use this battery will result of zinc substance with manganese. Heavy metal contain on this kind of battery are manganese and zinc. Le-Clanche battery will expel of reaction rest zinc chloride solution, and zinc rest of reaction include of heavy metal. Automotive battery usually use two type, wet cell type and dry cell type. Wet cell type usually use plumbum as electrode and sulfuric acid as electrolyte chemicals. Plumbum is heavy metal and sulfuric acid is reactive and corrosive chemical, that include of dangerous chemical if exposed to us.Dry cell battery use zinc and carbon as the electrode but use MnO₂ as electrolyte chemicals.

As the environmental regulation all battery type include in dangerous waste and should be process by waste process company before dispose.

Battery, How Can It Work

A Battery is essentially can full of chemicals that produce electron, chemical that produce electron is called as electrochemical reactions. Not every battery can rechargeable, this is because the chemicals inside the battery be activated again so that can function as the original one. Unfortunately this process can't work on and on, sometime the battery will died and can't be charged again.

We we look to the battery itself its contain two terminal or pole, one pole is marked by (+), while the other marked by (-) or negative pole. In large car battery, there are two heavy lead posts that act as the terminals.  Electron collect on the negative terminal of the battery. If we connect both terminal by a wire, the electron will flow from the negative to the positive terminal as fast as they can (and battery wear out very quickly). If you do like this can be dangerous especially for large batteries, so it is not recommended to connect of this two pole. If the reaction to fast the battery can be blow away and this very dangerous.

Tips: How to make battery more efficient

Make Battery More Efficient

More often you change your old batter, more waste battery will through away. More people know how to treat the battery, make battery more efficient, will make more least waste battery will through away. If you're a recent convert to smartphones, you're probably still discovering all the amazing things that your new BlackBerry, Android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your phone's battery lasts.

While a standard cellphone's charge can easily go three days or more, many smartphone owners are dismayed to learn that their new mobile toy requires charging every 24 hours, or even more often. It was great that I could use one device — my iPhone — to check my calendar and respond to multiple incoming calls during January's Consumer Electronics Show, but I paid the price when its battery died at 2 p.m.

The answer was not to desperately search for an electrical outlet to recharge the phone (though I've done that) or to consider giving up the phone (done that, too), but rather to figure out a strategy to reduce energy consumption while still having it available for essential tasks. Whether you're using a laptop or a smartphone, the devices can be tweaked to get the most out of its lithium–ion batteries.

Type of Battery and Its Waste Classification

Many kind of Battery type and Its Waste Classification can be collected into the table below, every type of battery can result different waste of battery, and the battery waste also can classified into several waste as the hazardous chemical class.

Waste Battery

Every battery models have chemicals and other materials that will rest after used, and then this waster battery can our environment pollute by this rest materials.

• Waste batteries may be considered hazardous waste because of their corrosive, reactivity, or toxicity.
• Typically Nickel-cadmium batteries exhibit hazardous waste characteristics but low-mercury alkaline and carbon zinc batteries do not.
• Larger mercury batteries would be likely to test as hazardous, and lithium batteries might be considered reactive.
• Lead acid batteries are considered corrosive, as well as toxic. (Gel cell batteries, are a subset of lead acid batteries, and should be treated the same.)
• Button batteries may or may not test as hazardous, depending on their type and size.

ROLES AND RESPONSIBILITIES
Logistic / Purchase Department by the possible means to purchase only low mercury (" green") batteries which are designated with the words, "low mercury", "zero mercury added", a green stripe, or a symbol that signifies environmentally friendly, such as a tree icon.

All users must;

• Substitute rechargeable alkaline batteries for nickel- cadmium to the maximum extent and completely in the end.
• Collect batteries for chemical waste pickup according to the recommendations in the table on the appendix.
• EHS department to ensure proper collection and carry out the legal disposal according to the applicable EHS legislation.

Guideline Battery waste reduction
Steps to minimize battery waste:

• Purchase only low mercury ("green") batteries which are designated with the words, "low mercury", "zero mercury added", a green stripe, or a symbol that signifies environmentally friendly, such as a tree icon.
• Substitute rechargeable alkaline batteries for nickel- cadmium.
• Collect batteries for chemical waste pickup according to the recommendations in the table on the reverse side.

Battery recycling
At the present time there are recycling outlets for lead-acid batteries, mercuric-oxide and silver-oxide button batteries. Find the legal recycling outlets Various consumer and industrial groups are working towards recycling options for other types of batteries.

Battery management
Using the table on reverse, try to identify the type of battery you wish to dispose. If you find that it should be disposed as a hazardous waste, you should request a pickup to a legal disposal company. If it is not considered a hazardous waste, it may be disposed in the trash.

Solar Cell Battery

On the current technology improvement, energy can be stored on the battery that is charge for several time using electric current that supply from any source like electric network that should be convert first to DC current and then store on the battery. Electric current source can be supplied from many sources, like from fuel generator, turbine generator, water turbine generator, steam turbine generator, wind generator or from sun light that usually called as Solar Cell.
Currently as the technology improvement, battery can store electric energy longer that before, as I have an emergency lamp, can keep for about 12 hours. Formerly I my emergency lamp just can store electric for about 3 hours. This improvement on battery technology make more efficient on using electric to supply electric to the charger.

On more sophisticated battery is used on automobile as drive motor to move the car, this really needs a perfect battery to store energy. This battery should be able to store energy for longer use, and have bigger power in order to move the car in high speed. If we have perfect battery to store energy we can use sun light to supply energy to the battery. We need solar cell to convert sun light into electric current and then store in the battery. We can use sun light just for 3 to 5 hours a day and can use this energy for a day even longer. So we can very efficient using other nature fuel source to fulfil our energy need on the house, on office, on the road and on small industry like pharmacy.

Solar cell is using material that has effect to exert electric or different potential to other material so that this unite material can build an electric current. This electric current then join together in order can use as electric supply and store on the battery as energy source.

Diaphragm Cells

Not like the other fuel cell, diaphragm cells contain a diaphragm, usually made of asbestos fibers, to separate the anode from the cathode. The allows ions to pass through by electrical migration by reduces the diffusion of products. Anodes have usually been made of graphite, cathodes of cast iron. Diaphragms permit the constructions of compact cells of lowered resistance because the electrodes can be placed close together. The diaphragms becoe clogged wit use, as indicated by higher voltage drop and higher hydrostatic pressure on the brine feed. They must be replaced regularly. The diaphragm permits a flow of brine from anode to cathode and thus greatly lessen or prevent side reactions (e.g. sodium hypochlorite formation).

Cells with metal cathodes (titanium coated with rare earth oxides, platinum or noble metals, or oxides) rarely develop clogged diaphragms and operate for 12 to 24 moths without requiring diaphragm replacements. It is expected that diaphragm made of corrosion resistant plastics will increase service life and remove the environmentalist’s objection to any process that may release asbestos fibers into the environment.

A major advantage of the diaphragm cell is that it can dilute (20%), fairly impure brine. Such dilute brines produce dilute sodium hydroxide (typically 11% NaOH with 15% NaCl) contaminated with sodium chloride as a product. Concentration to the usual shipping strength of 50% is required, and this consumes a great deal of energy even when multiple effect evaporators are used. Approximately 2600 kg of water must be evaporated to produce a ton of 50% caustic.

Primary Cells

Primary cells comprises of two sheet different metal plate or rod or a sheet of metal with carbon rod which placed on the electrolytic bath. The process on the bath will merge different potential between the dipped rods. If using copper rod and zinc rod will result electric potential different between two rod, if connected with wire will flow an electric current from the positive pole (+) to the negative (-). This process will stop sometime because polarization will happen on positive electrode, on this way cell can’t be used again but change with new one. Because of this condition, primary cells can’t be filled.

Simple form of Primary Cell: (1) Copper, (2) Zinc, (3) Electrolytic Solution, (4) Ampere meter, (5) Polarization on positive electrode.

Dry Cell also as an example of primary cells form, like on cell battery for electrical appliance that currently used also sample of primary cell form, such as on hand phone, watch, calculator computer and many others. Primary cell just for single use and can’t be filled after used change with new one. Primary cell is very marketable because beside of simple use, also can stand for long time if using the qualified of primary cells.
