what does a battery do?

In military science, a battery is a group of artillery guns or rockets, so grouped in order to facilitate battlefield communication and the organization of barrages. \n\nNaval batteries are a group of four or more cannons on a turret that fire in synchronization. In modern military organization, the military unit typically has 6 to 8 howitzers and 100 to 200 personnel. \n\nThey are subdivided into:\n\nField batteries, equipped with 105 mm calibre howitzers or equivalent; \n\nMedium batteries, equipped with 155 mm calibre howitzers or equivalent; \n\nHeavy batteries, which are equipped with guns of 203 mm or more calibre, but are now very rare; and \n\nVarious more specialised types, such as anti-aircraft, missile, or Multiple Launch Rocket System batteries. \n\nHeadquarters batteries, which themselves have no artillery pieces, but are rather the command and control organization for a group of firing batteries (for example, a regimental or battalion headquarters battery).

The motor may get faster. Batteries have two properties: current and voltage. \n\nIf the new batteries is added in parallel, the speed will likely stay the same, but the motor will be able to stay in motion longer due to resistance in the system, which limits the amount of current that can reach the motor.\n\nIf it is added in series, you double the voltage of the system, thus doubling the wattage (watts = current x voltage) and increasing the motors speed.

The chemicals of which it is made, and particularly the elements of the anode and cathode.  Each element has an electrode potential, ahd the voltage of a battery is the difference of these for the two electrodes.

I agree with the above answer. But I think you will find that freezing damages batteries. It is the refrigerator that extends life. But it does not increase the amount of energy in the battery. It only extends shelf life. That is because all batteries slowly self discharge while sitting on the shelf, so that after a few years, even though you never used them, they are dead. The cooler the temperature the slower they self discharge.

Chemicals... mostly some kinda acid. And some have nickle in it, but I donno if it'll be a solid (metal) or a liquid form. Bust one open and ya'll find out whats really in one.\n\nAnd also that's why they tell ya not to leave patteries in electonics for long periods of time with no use, cause the battery would start to leak the acid and it could fry the system.

Simple!\n\nJust a battery, resister, and the diode\n\nThe resister is determined by the size of the battery and the maximum allowable load on the diode. You have to have the diode specs to determine this.

Only if you have some kind of metal in your mouth, like a filling or crown.\nIt basically creates a battery, seeing that a battery needs and acid (saliva), and two metals (aluminum foil and the metal in your mouth).

Solar or light can be converted into current and batteries can be made at a smaller scale. Example is, small calculators are powered by solar cells.\n\nAs for as construction of those batteries they are made of smaller cells and then smaller cells are joint with other smaller cells to make little large cells. Its very expensive to make them on commercial level thats why we are addicted to oil.\n\nCheap things sometimes don't come cheap.

A battery eliminator is a device powered by an electrical source other than a battery, which then converts the source to a DC voltage that may be used by a second device originally designed to be powered by batteries.\n\nA battery eliminator does away with the need to replace batteries but may remove the advantage of portability. A battery eliminator is also effective in replacing obsolete battery designs.\n\nFor circuit diagram and working visit this link:\nhttp://homepages.which.net/~paul.hills/Emc/BecBody.html

It cause u nothing dear. It works on the battery. It helps u by noting dates, battery power etc, Ok na

"Repairing" your battery really depends on what kind of damage/use it has been subjected to. However, there are some ways to revive the battery life.\n\n1) Clean the contacts with a dry swab.\n2) Run several complete charge and complete discharge cycles.\nif this doesn't work...\n3) Place the battery in a freezer in a plastic bag for 12 hours. Remove it, wipe off any condensation, and let it thaw for 12-24 hrs before running more charge/discharge cycles.\n\nIf these don't work, it may be time for a new battery :-)

battery is used as a source of electricity. it can store energy of days or months.\nA capacitor on the other hand is an electronic component which stores charge for a very short time(around .5 seconds).It is used in electronic circuits.

You have to know with what kind of battery your starting.

For a period of time in the early 20th Century there WERE in fact B batteries. They were used to supply the ANODE voltage ( Plate voltage ) in vacuum tube devices like early radio equipment.  With the improvements that soon followed in converting AC to DC, it became less expensive to 'develop' the B voltage from a circuit called a 'power supply' and use of B batteries was confined to  'portable' devices.\n\nWith the development of the transistor, B voltage was no longer needed at all, and B batteries virtually disappeared from the market.

batteries have an electrolyte solution inside them;  when they get old this solution gets depleted of charge carriers, but i suspect you can recharge them by shaking them all around, thus mixing up the electrolyte and getting a bit more juice out.\n\nalso possible is that when you hold them in your hand when you take them out, the batteries warm up.  this warming means the ions in solution move faster, and therefore have longer diffusion lengths, so you can eke a few more minutes of game time out of them that way.  this effect (in reverse) is also responsible for your car not starting on very cold mornings.
