Batteries
Batteries are sources of chemical energy that are used in circuits to provide electrical energy for a wide range of useful devices. Any questions and answers regarding batteries or other power supplies would be welcome here.

How long will four Duracell AA batteries last in a digital radio?
About a year or two. Or maybe three.
What size batteries does a fossil LU 2526 use?
The Fossil LU 2526 watch typically uses a battery size of SR626SW. It’s always recommended to double-check the specific model or consult the manufacturer's guidelines for the most accurate information.
Your xbox 360 rechargeable battery pack wont charge?
This video tutorial by fraviaseeker worked for me.

It basically resets the batteries charge indicator circuit, which allows it to fully charge.
How do you recharge iPod nano battery?
when u buy ipod nano it has a usb wire in it . your connect it to your computer and other side in the ipod nano and then it will automatically start charging! :)
What is the comparison between capacitor and battery?
A Capacitor stores charge using a pair of parallel plates with an insulating material known as the dielectric separating them. When a current is applied to the capacitor, the electrons can't cross the dielectric so they build up on one side and leave the other, meaning the plates become charged. When the current is removed, the electrons flow back and the charge is reduced. The speed at which they do this is dependant on the size of resistor in the circuit.
A Battery (Cell) creates its own current through chemical reactions. There are two parts to a cell, each known as a half cell. Each half cell consists of an electrode, which is immersed in a solution. Copper and Zinc are common metals used for the electrodes. The solutions are usually made of the same substance in a compound which dissociates; the copper electrode would be immersed in, for example, a copper sulphate solution. An equilibrium is then established between the copper electrode and the dissociated copper ions, with the electrons flowing into the other half cell, creating a potential difference. This circuit is completed by a link between the two substances known as a salt bridge.
Capacitors are useful for fast charge storage over a short time period, though the rate at which they discharge is exponential. Batteries are useful for providing a slow, steady flow of electrons for much longer periods of time.
Hope this helps!
How many 1.5v cells are needed to make a 9v battery will these cells connected in series?
6 cells in series.
1.5+1.5+1.5+1.5+1.5+1.5=9
To find out how many cells are required, divide the final voltage by the voltage of the cells.
i.e. 9/1.5=6
They put a +(positive) and -(negative) on each side. The + matches with a - and vice versa.
How many cells does a 1.5 volt battery consist?
The familiar 1.5-volt zinc-carbon AAA, AA, C, and D cells, and the
familiar 1.2-volt alkalines in the same sizes, are each a single cell.
A dry battery and a wet battery and ...?
To put simply a "dry" battery is one that does not have any electrolyte (acid)... as such a dry charged battery is one in which the plate/cells of the battery are fully charged but will need to add the acid at the end user side before the battery is activated.
The Wet battery, is one that comes from the factory/production side fully charged and ready to use (with the acid inside).
Wrong. Both wet and dry batteries contain an electrolyte, but in the dry battery the electrolyte is absorbed into a solid material forming a damp paste. The dry battery is not really dry, its actually damp. The important difference is that the liquid electrolyte in a wet battery can spill and the damp paste electrolyte in the dry battery can't.
Lead-acid batteries are commonly shipped and sold without the electrolyte as this simplifies shipment and extends shelf life in the store. But they are still wet batteries as they cannot function until the electrolyte is added. True dry batteries need nothing added to function.
What type of energy is produced with a battery wires and a bulb?
The battery produces electrical energy. If the light bulb is connected between the
terminals of the battery, then the bulb will change the electrical energy into heat,
and if you're lucky and you have the correct voltage, also maybe some light.
What kind of jail time do you get in Nevada for battery domestic violence strangulation?
Are you sure you know what the proper charge is? From the question it sounds a lot more like 'Assault With Intent to Kill' rather than a simple Domestic Violence charge. It sounds like a felony charge which would signify, at the least, more than a year in prison.
Do trouble codes in cars go away if battery goes dead?
I have been told by more than 1 mechanic, that a code will remain in the computer until it is specifically cleared. most cars will clear the check engine light from the dash after a number of times being started.
Some computers will clear with a battery disconnect, some won't.
What advantage is there in arranging the batteries in series and in parallel?
A series connection of [five] cells gives you [five] times the voltage of a single cell.
A parallel connection of [five] cells gives you the same voltage, but [five] times the
battery life, of a single cell.
2006 Chevy Suburban doesn't start on first crank?
There are a few issues that can cause a 2006 Chevy Suburban to not start on first crank. These can include a dead or drained battery, problems with the fuel system, or issues with the starter.
Batteries contain something called electrolyte. In things like car batteries the electrolyte is often a liquid, which can be messy since liquids can leak. A gel battery is simply a battery using a gelled electrolyte.
