What is the charging time on a 9.6 volt battery?

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

How are generators and batteries different?

== == 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.

What does a battery use to produce electricity?

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.

What is the outer case of a battery made of?

it is made out of melamine because its hardcore like ethan slab ed joseph

Can you use a 9 volt charger for a 6 volt battery?

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.

Why does my smoke detector beep intermittenly with a brand new battery on Is there a smoke detector that does not beep intermittenlybut has a light indicator for battery operation?

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.

Can a 3.7 volt battery charger be used to charge a 6 volt battery?

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

Where can you find an outdoor lighting battery?

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.

How do you wire two 12 volt marine batteries together to run a 24 volt trolling motor?

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.

Why is steel not suitable for making the positive electrode?

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.

Explain what a dry cell battery is?

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.

What electrolyte is used in a lead storage battery?

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

What are two types of batteries?

Batteries can be classified in two ways

Primary Cell- Primary cell is a battery that is designed to be used once after that it can't be recharged with electricity examples are - AAA Cell (carbon Zinc battery) used in wall clocks,wrist watches etc.

Secondary cell- Secondary cell is a battery which can be recharged multiple times with electricity such batteries are- Ni-cad battery, Li-ion battery(used in mobile phones)lead acid battery -used for Back up in homes and office etc.

Does a 9 volt battery light a light bulb?

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

Why does electric fan and light click when power is turned on?

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.

Toy battery overheating?

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.

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.
