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
Fμs = 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:
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.

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.
