Not all types of batteries are dangerous. Alkaline batteries may explode if they have their poles inversely connected. Batteries used in vehicles contain lead and sulphuric acid that may be dangerous if inappropriately handled.
What happens when a battery light the light bulb?
When a battery is connected to a light bulb, the electrical current flows from the battery through the wire, causing the filament in the light bulb to heat up and emit light. The battery acts as a power source, providing the necessary voltage and current to illuminate the bulb.
alkaline batteries or other non rechargeables can be thrown away.
anything rechargeable needs to be recycled.
some states like California requires alkalines to be recycled.. something you might wanna check into first before you throw yours away.
A battery consists of five dry?
A battery typically consists of five elements: a positive electrode (cathode), a negative electrode (anode), an electrolyte that allows ions to move between the electrodes, a separator to prevent electrical shorting, and a casing to hold everything together. When a battery is "dry," it means that the electrolyte is in a solid state rather than a liquid or gel.
Where can you buy a 12V 600Ah nife battery in India?
You can try looking for a 12V 600Ah nickel-iron (NiFe) battery at specialized battery stores, online marketplaces like Amazon or Flipkart, or directly from manufacturers or distributors of NiFe batteries in India. Make sure to verify the authenticity and quality of the product before making a purchase.
Where is the batteries to the Nerf valcon go?
well, if you mean "Vulcan", if you turn the weapon upsidedown, look abit further from the trigger, you will see a little screw isolated to the others as the others are screwed into the sides, not the direct bottom. Unscrew it, pull out the chamber, and the batteries are there.
Is recharging a car battery endothermic or exothermic?
It's exothermic because it produces and releases excess heat.
Battery cages are small wire cages used in industrial egg production to confine hens. The cages restrict movement, do not allow natural behaviors, and can lead to health issues for the birds. Many animal welfare advocates argue that battery cages are inhumane.
If D batteries and AA batteries are both 1.5 volts why are D batteries stronger than AA batteries?
D batteries are larger than AA batteries, which means they contain more energy and a larger capacity to deliver power over a longer period of time. This results in D batteries being considered stronger than AA batteries, even though they have the same voltage.
What are Disadvantages of battery power?
Disadvantages of battery power include limited energy storage capacity, the need for frequent recharging or replacement, potential for environmental impact due to battery disposal, and slower charging times compared to refueling traditional energy sources.
Felony battery is a crime involving the intentional and unlawful striking of another person that results in serious bodily injury or involves the use of a deadly weapon. It is typically considered a more serious offense than simple battery, as it can result in harsher penalties, including imprisonment. The specific definition and punishment for felony battery can vary by jurisdiction.
How is electricity stored in batteries?
A battery consists of a group of 2 or more primary or secondary cells which convert chemical energy into electrical energy. One portion of the chemical energy is transformed into heat energy and the other portion into an electrical current.
Items that commonly contain batteries include smartphones, laptops, cameras, portable speakers, remote controls, flashlights, and electronic toys. It's important to properly dispose of these batteries to prevent environmental harm.
How does a battery store electrical current?
Batteries convert chemical energy into electricity. Batteries are made up of one or more separate sections, or cells, containing a chemical called an electrolyte.
Each cell has two electrically conductive electrodes immersed into its electrolyte. The electrodes are made of different materials; one releases electrons into the electrolyte, and the other absorbs them.
When an electrical device is connected to the electrodes, an electrical current flows through it and provides electric power for its operation.
Another answer
First we have to understand what a battery is made from. A battery consists of a number of separate cells. Each cell contains two different plates. The plates are held fixed and separated from each other. They are surrounded ("wetted" or "soaked") by a special chemical fluid or paste which conducts electricity.
One plate is called the "positive" ("+ve"), the other is called the "negative". ("-ve"). Every cell works because the plates react with the special chemical in such a way that an electrical current can be drawn off from the two terminals of the cell.
As current is drawn from the cell its plates - and the special chemical in which the plates are immersed - all gradually change their chemical composition. The result is that, as current is drawn off, the charge stored in the cell is reduced.
Another result is that the voltage given out by the cell drops. If nothing is done to replace the charge that has been taken from the cell then, eventually, a point is reached when no more charge can be taken out. That happens because the chemical composition of the plates and the special fluid can change no further. The cell is then called "flat" or "dead".
An even longer answer
"AA" and "AAA" are the international size references for two very popular kinds of cell. Size "AA" is bigger than size "AAA". These sizes are commonly used in flashlights, radios, MP3 players and personal amplifiers, etc. These cells each produce an output voltage of around 1.5 volts, direct current.
You can get them in two main kinds: "for-one-time-use" or "rechargeable".
To be able to explain how they work you will need to know what is inside them. If you have some knowledge of physics and chemistry that would come in handy too, but anyway here goes...
Any item with no moving parts which can produce a direct current flow of electricity is known as a "cell". Every cell contains two different plates. The plates are held fixed and separated from each other. They are placed in a special chemical fluid or paste which conducts electricity. One plate is called the "positive" ("+ve"), the other is called the "negative". ("-ve").
Each plate must be made of a different type of material to the other. The plates can then react with the special chemical in such a way that an electrical current can be drawn off from the cell. [It may be worth mentioning here that if both plates were made from the same material then no difference in voltage would be produced between them and no current could be taken from the cell. Nor could it be charged up.]
As current is drawn from the cell its plates - and the special chemical in which the plates are immersed - all gradually change their chemical composition. The result is that, as current is drawn off, the charge stored in the cell is reduced.
Another result is that the voltage given out by the cell drops. If nothing is done to replace the charge that has been taken from the cell then, eventually, a point is reached when no more charge can be taken out. That happens because the chemical composition of the plates and the special fluid can change no further. The cell is then called "flat" or "dead".
The actual types of materials used to make a cell determine the output voltage it produces. The physical size of a cell determines both 1) how much charge the cell can produce during its life and 2) how fast it can release that charge. (The bigger the cell, the higher is the total charge it can produce along with a higher charge release rate.)
There are lots of different types of AA and AAA cells. The name of the cell-type depends on the metallic elements and chemicals it contains. The name of the type of cell will normally be printed on the cell itself and/or on the packaging in which it is sold.
Common cell- type names are given to cells from the metals and chemicals used to build them, such as: "Zinc/Carbon", "Alkaline" (containing various elemental metals and/or metallic compounds), "NMH" (Nickel Metal Hydride), "Lithium Cobalt Oxide".
Many other sizes of cell are manufactured. Some sizes are available which produce a voltage that is not around 1.5 volts because they are made using different elements for the plates than the kinds used to make AA or AAA cells.
In general the output voltage depends on the materials which have been used to make the cell. Each lead-acid cell in a common car battery produces an output voltage of around 2 volts. Lithium cells produce around 3 volts.
Another short answer
For the invention of the battery we must thank the frog. In the 1780s the Italian physicist Luigi Galvani discovered a dead frog's leg would twitch when touched with two pieces of metal. Galvani had created a crude circuit.
The work was taken up by Professor Alessandro Volta. He created the Voltaic Pile, which is two discs: one made of zinc and one of copper, with a piece of cardboard soaked in brine between the two metal discs. This was the first "wet battery".
No we are not batteries, personaly I don't know specificly but I just know we are defenetly not batteries
YEAH WE ARE!!!!!!! HAMSTER WHEEL+ FAT PERSON+ TWEENKY= ENOUGH ENERGY TO POWER A SCHOOL!!!
How do you check the specific gravity of a battery?
To check the specific gravity of a battery, you will need a hydrometer. Remove the battery caps and draw some electrolyte into the hydrometer. Compare the reading with a chart to determine the specific gravity, which will indicate the state of charge of the battery.

How do you replace the battery in infiniti M35 key fob?
First you need to read the back of the fob. On the back is the number of the watch battery that you need to purchase. These numbers are important as the "button" batteries come in about 18 different sizes, and the size you need is usually sold in sets of two. After purchasing the battery, get a piece of white paper and put under your working surface...that screw is VERY tiny. Remove the screw and carefully remove the back of the fob. Inside you will find the batteries in a metal assembly. One can easily remove the battery with a flick of the fingernail. Carefully insert the new battery printed side up into the assembly, making sure that the spring metal is firmly seated against the side of the battery. Replace the fob back and re-insert the screw, making sure that the assembly is firmly reattached. Your local watch repair will perform this action for you for a very small fee. Walmart jewelry shop will do it for the price of the batteries.
You sure can! Lithium, in theory, can be recycled an unlimited amount of times and still be usable for creating more batteries. There are many areas and programs dedicated to recycling old electronics and the batteries that accompany them. Although it actually costs more to recycle a lithium battery than it takes to mine the lithium, recycling is still encouraged because demand for lithium is increasing and supply may shift in the future.
How do you remove rust on car battery?
Mix baking soda with water to create a paste, then use a toothbrush to scrub the rust off the car battery terminals. You can also use a wire brush or sandpaper to remove stubborn rust. After cleaning, apply a small amount of petroleum jelly to the terminals to prevent future rusting.
Yes, battery acid, which is typically sulfuric acid, is highly acidic. It can cause burns, damage to skin, and should be handled with care.
What is detonation out of battery?
"In battery" indicates that a rifle is ready to fire, a round is in place and the hammer is cocked.
"Detonation out of battery" indicates that the round went off before it was supposed to.
It could have gone off in the magazine, as it was being chambered, or as the bolt closed.
In a revolver, it would mean that a chamber in the cylinder that wasn't lined up with the barrel discharged.
Revolvers and multi barrel pistols that are charged with black powder are noted for this.
Black powder is concussion sensitive and a chamber can detonate when the chamber next to it was discharged.
Putting the wrong ammo in a gun with a tube magazine can also cause this.
The primer can be touched off by the point of the round behind it causing all the rounds in the magazine to detonate.
Is electromotive a physical or a chemical property?
Its a physical property as it is not involved with chemical reactions.
What is the chemical found in batteries called?
The chemical found in batteries is usually a combination of various chemicals, with common ones being lithium, nickel, cadmium, lead, and alkaline materials such as manganese dioxide and zinc. These chemicals undergo reactions to produce an electrical current.
In a desktop computer the battery is located on the PC motherboard. It looks like a silver button about the size of a quarter, in the center of a black circle of plastic. In a laptop the battery is quite a bit larger and is usually found on the bottom of the laptop near the back, underneath the screen hinge.
