What happens if a car battery is not used for a long time?

User Avatar

Asked by Wiki User

If a car battery is not used for a long time, it can experience several issues due to a process called self-discharge and other factors. Here are some potential problems that may arise:

Self-Discharge: All batteries, including car batteries, naturally lose their charge over time, even when not in use. This is known as self-discharge. The rate of self-discharge depends on various factors, including the battery type and temperature. If the self-discharge is significant and the car is not used for an extended period, the battery may drain completely.

Sulfation: When a lead-acid battery, common in many cars, is left in a discharged state for a long time, sulfur crystals can form on the lead plates inside the battery. This process is known as sulfation, and it can reduce the battery's ability to hold a charge. In severe cases, sulfation may lead to permanent damage.

Low Voltage: If the battery voltage drops too low, it can affect the performance and lifespan of the battery. Modern vehicles with advanced electronic systems may experience issues or malfunctions when the battery voltage is too low.

Freezing: In cold climates, a partially discharged battery is more susceptible to freezing. When the electrolyte inside the battery freezes, it can cause internal damage and reduce the battery's effectiveness.

To prevent these issues, it's advisable to take certain precautions if you know the car won't be used for an extended period:

Keep it Charged: If possible, use a battery maintainer or trickle charger to keep the battery charged. These devices supply a low current to the battery, preventing self-discharge and maintaining an optimal charge level.

Disconnect the Battery: If you're not using the car for an extended period, consider disconnecting the battery to prevent any slow discharge due to the vehicle's electrical systems.

Store in a Controlled Environment: If feasible, store the vehicle in a cool, dry place. Extreme temperatures, whether hot or cold, can accelerate the self-discharge process.

By taking these precautions, you can help ensure that your car battery remains in good condition, even if the vehicle is not used for an extended period.

You shouldn't. Batteries are terrible for the environment. Look for battery recycling facilities in your area to prevent poisoning our water.

Can the human body drain a battery?

User Avatar

Asked by Wiki User

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.

Which is better lithium or lithium-ion battery?

User Avatar

Asked by Wiki User

Yes, there is a difference between a lithium battery and a lithium-ion battery.

A lithium battery is a primary battery, which means it is a non-rechargeable battery. It uses metallic lithium as an anode and an oxidizing agent, such as manganese dioxide, as a cathode.

On the other hand, a lithium-ion battery is a rechargeable battery that uses lithium ions as the charge carriers. It uses a carbon-based material as the anode and a metal oxide as the cathode. Lithium-ion batteries are widely used in portable electronic devices and electric vehicles because of their high energy density, low self-discharge rate, and long cycle life.

So, while both types of batteries contain lithium, they have different chemistries and properties. Redway Power is brand that specializes in lifepo4 battery manufacturing that is a type of lithium ion battery

What type of batteries does a shock pen have?

User Avatar

Asked by Wiki User

These gag pens mostly use "AAA" size cells. They are, after all, "pens" as in the writing instrument. The triple A cell will fit inside the body of the pen and it won't look too "fat" to alert a potential "victim" to the prank. Original answer by Quirkyquantummechanic

Some shock pens use mercury batteries for size because they need to fit it in.

Why is a 9v battery smaller than a 6v?

User Avatar

Asked by Wiki User

It really boils down to the amount of power that the battery can 'store'. Smaller batteries are convenient but actually store less power than the larger, bulkier batteries do.

Since POWER = VOLTAGE x AMPERAGE and the overall power is less in the higher voltage battery, then, it must mean that the amperage, or current available in the 9 v battery is less in the long run than the 6 v battery.

For instance, an automobile battery is 12 v and has to pack quite a wallop to get a car started, yet there are much smaller 12 v batteries but they'd never be able to generate enough amperage to start the car.

How the Okapi gets its needs?

User Avatar

Asked by Wiki User

It eats many different types of vegetation, some of which is poisonous to humans, by using its long tongue to grasp and pull. It will consume red clay by the rivers to get its mineral requirements, and also consumes charcoal from lightning struck trees. Some say that this adds more minerals to its diet, while others say that it counteracts the poison that it consumes.

Disadvantages for battery farming?

User Avatar

Asked by Wiki User

Battery farmed chicken is cheaper than free range, but that is the only thing about battery hens that are good. When you eat plant foods, all the energy and material from that plant goes straight to your body. If a hen eats the same plant food, and soon it would be killed to that it could be eaten, not all the original energy and material that was in the plant would be passed on to your body.

The reason for this is because when the animal was alive, it took almost all of it energy it needed for itself and much of would go out through the body by faeces. This means this less and less energy that comes to us. This is one reson why battery hen farming is a effienct way of producing food!

Not only that put the air is kept warm in its cages, so that less energy converted to heat!! Disadvantages- Some ethical issues- People think that battery farming is morally wrong. Hens cannot carry out natural behaviour such as preening, scratching, dust and water bathing and rustling of feathers because of lack of room to move. Their bodies grow too quickly due to their diet and their legs cannot grow as quick, so the legs give way and break, which is very distressing and painful for the hen. The hens develop severe behaviour problems and can attack each other. ---- Advantages- They are fed high protein diets to make them grow very big very quickly, so manufacture of hens is quicker and the meat will also be tender, due to the chicken being young. The restricted space to move means they do not use the energy from the food they eat to move around. Energy is also conserved because the cages they are kept in are kept very warm. This means more of the energy from the chicken comes to the consumer.

How do you open a tamagotchi hexagontchi so you can put batteries in it?

User Avatar

Asked by Wiki User

There are two holes with buttons in them on the back of the tamagotchi. The bottom one resets the tamagotchi. The top one opens the battery cover. You need something small enough to fit in the hole(like a paperclip, toothpick, etc.) Press the button and then you will be able to slide the battery cover off.
