Batteries

Because they have internal resistance. Current flow through this internal resistance produces heat, just like current flow through ordinary resistors does. The current can be from use of the battery or charging the battery (if it is rechargeable). Usually the internal resistance of a battery increases with age, meaning older batteries tend to run hotter than fresh ones.

generally speaking, there are several LED lights on the battery charger, when the light is red, it meas the battery is being charged, when the light turn to green or yellow, it means the battery is full charged

They weren't, they were single-use. Pick the two correct metals, stick them close together in an acidic bath, and they'll deliver a voltage and a current until one of the metals is all used up. No charging required.

To measure battery current, you can use a multimeter set to measure current in series with the battery. Connect the multimeter in series between the battery and the load to measure the current flowing from the battery to the load. Make sure to select the appropriate current range on the multimeter to avoid damaging the instrument.

You can make a battery out of both a lemon or a potato - if you want to see how just do a net search on "potato battery" or lemon battery.

In science we have been conducting an experiment to see which of the fruits/vegetables creates a larger flow of electrons- for us it was the potato so it may make a better battery than the lemon.

u make it by putting a penny in a lemon and a nail on different sides, then use a battery meter to see how much electricity the object has.

If you're relatively handy, this is not a difficult task. The hardest part will be opening the enclosure the control panel sits in.

A typical residential burglar alarm will have a main CPU or control panel usually located in a closet. Depending on the brand, it will be securely closed with a lock or screws. In either case you'll have to get it open. Unscrew, pick the lock, drill the lock, etc. Once inside, you'll see two wire leads (usually RED and BLACK) connected to what looks like a brick shaped object. Sometimes it'll be rectangular and other times it'll be almost cube like. That will be the battery. Carefully pull the two leads off of it, go to your nearest source for specialty batteries (batteries plus?) and purchase compatible model. If the alarm system is disarmed, the beeping will go away after your replace the battery and it charges to capacity. The most important factor will be the size of the connectors and the voltage of the battery (usually 12V). It does not have to be the same brand.

A AAA Duracell battery typically lasts between 3 to 5 years when stored properly in a cool, dry place at room temperature. The actual usage time of the battery will depend on the device it is used in and how frequently it is used.

A battery burns out when its chemical reactions are depleted and it can no longer provide the necessary voltage to power a device. Over time, repeated charging and discharging can also degrade the battery's capacity, leading to its eventual failure.

Yes, as long as you use an NiCd charger, but you really shouldn't. NiMh has twice the capacity of NiCd and it is less expensive. NiMh also contains no toxic materials so it is better for the environment.

Although an early form of battery may have been used in antiquity, the modern development of batteries started with the Voltaic pile, invented by the Italian physicist Alessandro Volta in 1800. The widespread use of batteries has created many environmental concerns, such as toxic metal pollution.Many reclamation companies recycle batteries to reduce the number of batteries going into landfills.Early batteries were used for experimental purposes. He based his works on another Italian doctor named Luigi Galvini. Galvani discovered electricity. Alessandro based his works on his experiments. Though, Volta and Galvani were rivals at heart. They strongly disagreed, and so did their children.
i think it was Isaac newton but I'm not 100% sure

A regular battery uses chemical reactions inside a closed casing to produce electricity, while a lemon battery uses the acidic juice of a lemon as an electrolyte to generate a small amount of electricity through a chemical reaction between the lemon juice and metal electrodes placed in the lemon. Lemon batteries are typically used for educational purposes to demonstrate basic concepts of electricity generation.

The purpose of a battery is to provide power/electricity to the circuit or other object.

to provide energy for the current to flow

The electrical cell/battery is designed to store energy in chemical form, and to

deliver it in electrical form when required.

Yes, batteries can be recycled. Different types of batteries (such as lithium-ion, lead-acid, and alkaline) require different recycling processes to recover the materials within them. Many recycling centers and retailers offer battery recycling programs to properly dispose of old batteries.

While it is indeed true that all animals give off minute electromagnetic energy, no person can drain a battery no matter how much moving they did. The battery would drain of age before that happened.

I must respectfully disagree. The degree of electromagnetism varies person to person and is often an inherited condition. I can only wear a watch for two to three days before the battery goes dead. Any time I touch metal a visible spark can be seen and felt! Also, certain machines will power down, even during full use just by simply walking past them. In my case I believe it's an inherited condition, I have a few family members who cannot even ride in cars with computers without the entire electrical systems fully melting down. However, I have been able to find only a handful of other cases similar to my own and even fewer similar to my family members. But it is completely possible for the human electromagnetic field to drain even car batteries.

I find this phenomenon interesting. Although it sounds impossible we have to remind ourselves that many things we know as fact today were considered impossible in history. With that said, my interest in this topic lies with the fact that a good friend of mine has this ability. She recently went through 4 battery packs in a walky-talky during a hazard drill. Each pack was fully charged when given to her. Everyone else's lasted the full 8 hours. She could only get about 2 hours out of each. So I started researching things like Bioelectromagnetism, and bioelectricity. I found that based on Sodium, Potassium, Protein, and a few other elemental levels in the human body, the human cells produce a bioelectrical "charge" to adjust the element levels to where they need to be. This led me to think that it was a case of diet, or % body fat that enabled this ability. My friend is extremely fit and muscular so body fat would be extremely low. Low body fat would lead to lower electrical impedance making it easier for electrical current to travel through the body. A walky talky, like a watch or phone, is always running and therefore sending out some frequency which draws on the battery. My current "theory" is that her low fat body is a much better conductor (or would it be insulater?) than the average person since it will have more water. Therefore the body is drawing in the frequency better. Because it's getting drawn into her instead of broadcasting the device has to work harder to broadcast and is therefore draining the battery.

Because a battery cannot invert its polarity - batteries will always have one positive and one negative lead and it cannot be changed.

Alternating current is just what it says; at the top of the first cycle Lead 1 is positive and Lead 2 is negative, at the bottom of the cycle Lead 1 is negative and Lead 2 is Positive (explained as mid cycle to avoid confusion; in reality each 'cycle' starts with the transition where both leads transverse the zero volts threshold).

In the Toyota Tarago, also known as the Toyota Previa in some regions, the battery is typically located under the hood of the vehicle. It is commonly found on the driver's side of the engine compartment, near the front of the car. Be sure to refer to the owner's manual for precise instructions on how to access and replace the battery in your specific model.

To prevent a battery from blowing up, avoid overcharging, puncturing, or exposing it to extreme temperatures. Use only the approved charger for the battery and follow the manufacturer's instructions for proper handling and disposal. If a battery appears swollen or damaged, stop using it immediately and consult a professional for safe disposal.

The major constituent of car battery acid is aqueous sulfuric acid. Ideally, it contains sufficient water to attain the maximum electrical conductivity for mixtures of H2SO4 and H2O, about 40 % water. Battery acid may also contain other substances, usually corrosion inhibitors of some kind.

No, D batteries can vary in terms of brand, capacity, chemistry, and intended use. It is important to check the specifications of the D batteries to ensure they are suitable for the intended device or application.

That depends on the type of battery. There are nickel cadmium, lithium, lead acid,

The newer type of sealed nonspillable maintenance free valve regulated battery uses "Absorbed Glass Mats", or AGM separators between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled, but can take much more abuse. These are also called "starved electrolyte." Just like the Gel batteries, the AGM Battery will not leak acid if broken. By www.batteryplex.com.

The object that uses electricity in a circuit to make something happen is known as the load. Usually the load is rated in watts.

Sure....Just go to the GM website and follow the instructions. You will need you VIN number from your vehicle....here is the link....

Yes, connecting a battery charger the wrong way around can cause damage to the battery, possibly leading to overheating, leaking, or even explosion. It can also damage the charger itself and the connected device or vehicle. It's important to always double-check the polarity before connecting a battery charger.
