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 fs so:

Fs = fs ----> Fs = μsN = μsmg

by definition, the formula for centripetal force is

s = mv2max /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.

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.

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.
