Batteries

There is no answer to this question. It could be anywhere between 2.5V and 12V. If you connected them in series the answer would be 20.5V, in parallel the higher voltage battery will discharge into the lower rated cells, the resultant voltage is dependent upon the internal resistance of each of the batteries. In practice you wouldn't do this, so it's either a mistake or trick question. www.powerinspired.co.uk

You can make your own battery, or you can use a generator of some sort.

To make a battery, you need an electrolyte of some sort and electrodes from opposite ends of the period table. You would likely use zinc for one of the electrodes and copper or carbon for the other. You could use citrus fruit or potatoes for the electrolyte medium, and place the electrodes into them.

For a generator, you would need to create moving magnetic fields inside of coils of wire. You would have to create the movement at a steady rate, and use circuits to regulate the voltage and current produced.

"Battery limits" in general simply outlines the limits of the work to be done by the engineer. If a refinery asks an engineer to carry out some work on the refinery, the battery limits need to be defined in order to determine what the engineer is responsible for and what he is not responsible for.

In the case of a refinery, for example, the battery limits might include sizing and costing a new heat exchanger. It could include the cost of utilities, installation, electrical needs, maintenance. Outside the battery limits might be how the utilities are supplied, how this heat exchanger is going to be delivered, who is going to build the exchanger etc.

What is the difference between cylindrical and prismatic battery cells?

As Professor Jones PhD of the Royal University of Malta's Department of Engineering and Science we have been conducting studies into the long term effects of licking a battery terminal to test for power as some people call it! Our Studies have proven that you are 87% more likely to die from a spontaneous static shock later in life. Other studies have shown that you are more likely to die from licking from a battery than being run over by a Double Decker bus in London. During our study we took a case study in the USA and 87 out of every 100 samples had signs of significant battery and electronic related defects. I URGE you as a professional NOT TO LICK BATTERIES or you will suffer consequences as we found out with the 85 out of the 100 sampled that spontaneously fell to the ground......this is SHOCKING isn't it!!

No, not unless it has a voltage or current regulator or series resistance to limit the current (built in somewhere).

== == batterys are stored. cranks are made

----------------------------------------------------------------------------------------------------------

While I can not argue with this answer I can add some to it.

If you are defining electricity as the flow of electrons in a circuit, then the general answer to the difference between the electricity from the battery and the generator is stored energy and produced energy.

The battery is always going to be DC (direct current) and a hand cranked unit almost always will be to. The primary measurable difference is going to be that the battery will be a steady voltage at a steady draw on it at least as far as the "life" of the batterys charge lasts.

The hand cranked generator usually also direct current, (unless it is a high end model with a built in regulator) will most likely vary its output voltage and amperage depending on the cranking speed.

Basically though the idea of either is delivering a flow of electrons steadily to the load, a light or motor etc..

AC or alternating current is produced differently and actually changes the direction of the electron flow very quickly.

a battery has potential ( voltage). without a circuit atatched to it nothing happens. But when used in an electic ciruit, like with a light bulb, current will flow(amps). current flow is what causes your light bulb to light. A battery has the pressure (voltage) so to speak to cause current flow. Generally, current flows from negative to positive ina complete circuit.

This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.

More than likely the cool temperature is causing a marginally good battery to fail the automated battery test. This test applies a brief resistive load to the battery that simulates the power required to sound an alarm. If the voltage falls below a predetermined level, an audible chirp is generated to indicate battery replacement is needed. Cool temperatures affect the battery chemistry in such a way that the voltage will be lower during this test. As a side note, use of lithium batteries in a unit designed for alkaline batteries will exacerbate this problem.

Short answer, no.

Not so short answer, it depends on the battery's chemistry. In all cases, you're not going to charge it completely no matter the chemistry, but you might charge it anywhere from nothing to ~75% depending on the chemistry and the 6 volt charger's top voltage(It's not 6 volts! If it's a lead charger, you might expect a top voltage of ~6.8 volts). Also, you want to make sure the charger's amperage doesn't exceed the battery's charging current's ability or you might overheat the battery and destroy it.

In a longer answer, it is possible to convert a 6 - 7 volt supply to 8-9 volts with a "boost up" converter but that's either going to require buying the device or making it yourself. Even if you we're to do that, you need to make sure the battery's chemistry's safe limits aren't exceeded. NiMH, for example, has a quick downtown in its voltage near the end of its charging, and if the charging isn't cut-off there, the battery will keep absorbing charge until it overheats and explodes. another comment: yes if it fits into the device normally though it would take a little longer to charge

You can find outdoor lighting batteries at hardware stores, home improvement stores, online retailers, and specialty lighting stores. They are typically located in the electrical or lighting sections of the store.

To get 24v from two 12v batteries you just link between ones positive and the others negative then connect your motor to the spare terminals, but your 12v charging system will not charge them (and any 12v equipment connected to them will burn out!) without removing the link.

Actually alkaline batteries use a steel cup coated with carbon as the positive electrode. However the steel is purely structural to support the carbon coating and to prevent leakage of the electrolyte. It does not participate in generating the electricity.

There are two conductors were electricity begins and runs through wires which make energy come out of a battery.

In the center of each cell there is a rod called a cathode. It is usually composed of graphite. Surrounding this cathode there is an electrolytic substance which acts as a medium to conduct electricity. The cathode and electrolytic substance are separated from the outer container by a cardboard tube. This assembly is sealed into a metallic cylinder. In older type batteries this cylinder was made of zinc. This part of the battery is known as the anode. When a load is connected between the cathode (+) and the anode (-) terminals, a chemical reaction takes place between the cathode and the electrolytic material. This chemical reaction generates a 1.5 volt potential between the two terminals.

The electrolyte in a lead storage battery is a solution of sulfuric acid and water.

Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.

I am going to guess that you are talking about a ceiling paddle fan with remote control (the remote being either hand-held or in the wall box) The click sound you are hearing is likely the click of the relay in the electronic control module inside the ceiling fan. This module contains the actual power relay that turns the power on and off. There is one relay for the fan and another for the light. When you press the on-off buttons on the remote, it sends a radio signal to the control module and activates the relay. You can't hear the radio signal but you hear the relay click.

If a toy battery is overheating, it is crucial to take immediate action. Safely remove the battery from the toy, place it on a non-flammable surface, and avoid touching it directly. Prevent further overheating by keeping it away from heat sources and contact the manufacturer for guidance or disposal instructions.

Use a hammer and gloves.

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.
