What is the voltage of energizer lithium batteries?

User Avatar

Asked by Wiki User

Energizer (and many other battery companies) sell two kinds of "lithium" batteries:

"Lithium Photo/Coin", Li-Mn, "CR" button cells, such as the CR2032, provide about 3 V.

"Lithium cylindrical", "Lithium-iron", "Li/Fe", which comes in AA and AAA, are about 1.5 V, and also comes as those rectangular 9V batteries, which... of course... are about 9V.

Asked by Wiki User

A typical battery consists of an anode (negative terminal), cathode (positive terminal), and an electrolyte solution. The anode is typically made of zinc, the cathode is made of manganese dioxide, and the electrolyte solution is usually an acid or alkaline solution.

Do you have a diagram on 9volt battery and light bulb?

User Avatar

Asked by Wiki User

I can't display images. However, a 9-volt battery can be connected to a light bulb by attaching one end of a wire to the positive terminal of the battery, and the other end to the bottom tip of the bulb. Then, connect another wire from the top tip of the bulb to the negative terminal of the battery. When the circuit is complete, the bulb should light up.

How do you get a battery out of a phone?

User Avatar

Asked by Wiki User

To remove a battery from a phone, you typically need to first power off the device. Then, locate the battery compartment on the back of the phone and remove the cover. Finally, gently pry the battery out using your fingers or a tool if needed. Note that not all phones have removable batteries.

Why does a battery corrode?

User Avatar

Asked by Wiki User

A battery can corrode due to a chemical reaction between the electrolyte and the metal components of the battery. This reaction can lead to the formation of corrosive byproducts, such as hydrogen gas and metal oxides, that can damage the battery's terminals and casing. Environmental factors, such as moisture and temperature, can also contribute to the corrosion of a battery.

How many AA batteries make a pound?

User Avatar

Asked by Wiki User

It would take about 30 AA batteries to make a pound. Each AA battery typically weighs around 0.8 ounces, so you would need 16 batteries to equal one pound.

A battery charger uses 15 watts At 6 cents per kilowatt-hour how much does it cost to charge batteries for 24 hours?

User Avatar

Asked by Wiki User

To find the cost, we first calculate the energy consumption in kilowatt-hours by converting the watts to kilowatts (15 watts = 0.015 kW) and multiplying by the number of hours (0.015 kW * 24 hours = 0.36 kWh). Then, we multiply the energy consumption by the cost per kilowatt-hour (0.36 kWh * $0.06/kWh = $0.02 or 2 cents). So, it would cost 2 cents to charge the batteries for 24 hours.

Will a 3.6V battery replace a 3.7V battery on cameras?

User Avatar

Asked by Wiki User

It is not recommended to replace a 3.7V battery with a 3.6V battery in a camera as the slight difference in voltage may affect the camera's performance and potentially cause damage. It is best to use the battery specified by the manufacturer to ensure proper functioning and safety of the camera.

Can you eat a battery?

User Avatar

Asked by Wiki User

No, you should not eat a battery as it can be toxic and harmful to your health. Batteries contain chemicals that can cause serious health issues if ingested. If you suspect someone has ingested a battery, seek medical help immediately.

How does a battery charger charge a battery?

User Avatar

Asked by Wiki User

A battery charger works by converting electrical energy from a power source into the appropriate voltage and current needed to charge a battery. This process involves regulating the flow of electricity to ensure that the battery receives a safe and efficient charge, typically through a series of electronic components such as rectifiers, capacitors, and control circuits.

What does a battery cell do?

User Avatar

Asked by Wiki User

A battery cell stores chemical energy and converts it into electrical energy through a chemical reaction. This stored energy can then be used to power various devices such as smartphones, laptops, and electric vehicles.

Where is the battery xc90?

User Avatar

Asked by Wiki User

The Battery is mounted in the boot (trunk) of this vehicle.

To access you need to go into the boot, lift the rear cover off (from the floor)

You should see the battery sitting in the middle of the rear (with a black plastic cover)

N.B. you can jump start this vehicle from the engine bay - where a positive feed (marked in red) is located by the front fuse board.

What is a central battery?

Why don't we get most of our electricity from batteries?

User Avatar

Asked by Wiki User

Batteries store electricity but they do not generate it. Most of our electricity comes from power plants that convert various energy sources (such as coal, natural gas, nuclear, or renewable sources like solar and wind) into electrical energy. Batteries are typically used for storing and supplying smaller amounts of electricity or for backup power in case of outages.

What does a bad cell in a battery cause?

User Avatar

Asked by Wiki User

A bad cell in a battery can cause reduced overall battery capacity, shorter battery life, and potential overheating or safety issues. It can also lead to uneven charging and discharging of the battery, which can affect the performance of the device powered by the battery.

Why do you prefer NiMH batteries?

User Avatar

Asked by Wiki User

I prefer NiMH batteries because they have a higher energy density, meaning they can last longer between charges compared to other rechargeable batteries. They are also more environmentally friendly as they do not contain toxic chemicals such as lead or cadmium. Lastly, NiMH batteries are more cost-effective in the long run as they can be recharged hundreds of times.

What is a 3 volt battery?

What are the advantages and disadvantages of obtaining electricity from cells and batteries?

User Avatar

Asked by Wiki User

I assume you mean "Photovoltaic cell." If so, here they are:

Advantages: No environmental impact and is a renewable energy source.

Disadvantages: Currently very expensive, very innefficient (only collects 30% of the potential energy), and unreliable (if a cloud covers the sun, no more energy is being collected).

Also, remember, I am just a random person on the internet stating my views, so be sure to check out all of my information, making sure that it is correct, before using it in a paper or something :-)
