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.

Are lithium batteries better than nickel metal hydride batteries?
Yes because they use less chemicals, last longer per charge and last through more charges
lithium batteries are non rechargeable. Lithium ion batteries are rechargeable.
lithium batteries last a lot longer than standard alkaline batteries and work well in digital cameras and stuff that are high drain.
NiMH is also good for the same purpose.
it depends on your preference. if you dont mind charging the batteries multiple times than go with NiMH. if you want to use something for a good while and throw them away, use lithium. both have their pros and cons.
How many volts can a lime produce?
The voltage an electrochemical cell produces does not depend on the electrolyte (e.g. type of fruit), it depends on the two electrodes (e.g. metal strips).
The voltage is determined by the relative electronegativities of the two electrodes. For example all cells using a copper electrode and a zinc electrode will produce the same voltage, regardless of the kind of electrolyte they are put into.
Another example all cells using a carbon electrode and a zinc electrode produce 1.5 volts, regardless of whether the electrolyte is acidic (the original dry cell batteries), basic (modern alkaline batteries), or neutral (a salt).
How severe can an AAA breakdown be?
An AA breakdown can be quite severe in many cases. Just over a month time span the company had to report to over half a million breakdowns.
How do you rejuvenate Nicad batteries?
There are a few ways to do this.
Using a welder for a D.C. source to zap the battery. A car battery should accomplish the same task. Dangerous as it could explode the target battery. Not for amateurs.
Buy a downloadable manual to tell you how.
Buy sub C batteries to replace the ones in a battery pack. Soldering experience necessary. On the first link scroll to the first comment.
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.
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 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! :)
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.
