# Why do batteries lose charge if placed on cement?

###### Wiki User

It actually is based upon temperature-----. Batteries are insulated in a plastic or rubber case, so electricity leaking to the cement is not in the question. Even more so, batteries normally sit in a metal tray in a car. If battery leakage were to occur, it surely would sitting on metal.

The actual cause is temperature difference between the top of the battery and the bottom. The specific gravity of the electrolyte changes with temperature. Therefore the specific gravity of the electrolyte is less at the top of the cell and more at the bottom. As measuring the specific gravity tells the state of charge of the cell, the cell has more of a charge at the top of the cell than the bottom. This causes an internal current drain inside the plastic battery case.

All batteries will discharge no matter where they are sitting when not being used. This is called "Shelf Life". A battery will not be damaged by sitting on a concrete floor versus sitting on wood. You will just have to charge it up to use it. It should be noted that a lead acid battery will eventually sulfate the longer it is discharged. Sulfation is not fully reversible.

People who believe that a battery is ruined by sitting on a concrete floor don't realize that probably the battery was acting up to begin with and was removed from a vehicle because it was going bad. After sitting on a concrete floor for a period of time, they try to charge the battery and find it bad. Therefore the conclusion was that the concrete floor ruined the battery instead of the battery getting plain worn out from usage in a vehicle.

It is all due to temperature and nothing else.

No they lose some of its power over time. it depends on the type of the battery. rechargeable lose more of there charge that normal battery's.

small battery can lose charge fast,and big batteries can loose charge at large time

Dead cell in the battery or something is on pulling power from the battery. Light or relay.

We know that AA batteries (or any others) lose charge because energy is taken out of them with use. The chemical reactions that generate the voltage occur, and this "uses up" the energy in the cell. This is the long and short of why batteries lose charge, and you can see it if you think it through. We can also see a situation where a cell loses charge when stored. No materials are perfect insulators. And lengthy storage, or storage under improper or poor circumstances will set up conditions under which leakage current could discharge a cell. Plain and simple.

Lithium ion batteries are supposed to last longer than nickel batteries. They do not lose charge for up to 10 years in their packaging, and they last longer while in use as well.

Yes, batteries lose energy. If you leave something on that has a battery in it, then the battery will lose it's energy and you must throw it away.

Rechargeable batteries lose their effectiveness over time. You could try discharging the battery completely and then recharging. However it is likely you may need a new battery.

They don't. That is an old myth. The only kernel of truth comes from the floor usually being colder and a cold battery will have less power. If concrete allows electricity to "leak" out of the battery, then the battery sitting on a metal tray in most cars,trucks, and part stores would kill every battery out there.

Many laptop batteries last for years without a problem. You need to take good care of them, however. These batteries tend to lose their charge capabilities over time, and this can be sped up if you keep your laptop plugged in all of the time. If a battery is not going to be used, it probably will not last for a long time.

No not really. But it depends on the type of battery you are using. Basically the only battery that you can get more use out of if you put it in the refrigerator is NiMH and Nicad batteries, (mostly used for electronics) because those kinds of batteries lose their charge after a few days. So if you keep them in the fridge they will retain 90% charge for months. But other then that, putting batteries in the freezer or fridge is not recommended. Also, if you put batteries in the fridge, when you take them out you have to wait until the warm up a bit before you use them.

With the cost of new batteries being as high as they are today, buying rechargeable and replacement battery sets is much more cost-effective. This choice also reduces the amount of hazardous waste emptied into the landfills. Recharging devices and battery sets can be purchased for about the cost of 50 batteries. Most have a recharge number of at least 1,000. When used incorrectly, these batteries may have a much shorter life. This article will explain how to maximize the life of rechargeable batteries.Be sure to use the batteries and chargers from the same manufacturer. For example, don't use a Duracell battery on an Energizer charger. Not all rechargeable batteries are made exactly the same, so this is very important. Some chargers may not be designed to charge other types of batteries, resulting in a slight charge and shorter overall life. Never over-charge a battery. When they are over-charged, they also overheat, which takes a great portion of the battery's life.Always use the entire charge on a battery. Every time the battery is placed in the charging unit, this initiates a new cycle. Most people are unaware of this fact; it is not usually printed in instruction manuals or on the device's package. Using the battery for a while, then placing it on the charger when it has 30% of its charge cycle left will result in loss of that 30%. Each trip to the charger is what weakens the battery, even though it will be fully recharged. Always keep this in mind when deciding when to place batteries in the charger. Always keep a replacement set fully charged and ready to go, so it will be possible to use the entire charge cycle without being inconvenienced.Don't let charged batteries sit unused for long periods of time. It is best to use batteries as soon as they're charged - or shortly after. If the replacement batteries must sit for a long time, charge them no more than a week or two before they will actually be needed. However, don't let the battery sit with absolutely no charge. There should be a charge of about 20%-50% as it sits. When batteries sit unattended, they will automatically lose their charge. A completely empty battery will stop working faster and the number of effective charge cycles will be reduced if it sits empty for a long period of time. Batteries should be stored away from sunlight in a cool and dry location.

Ni/Cd or Nickel Cadmium rechargeables and many of the metal hydride batteries recrystallize as they heat and cool due to the action of the electric charge. This affects their ability to store charge. Lead acid batteries develop sulfur based corrosion on their metal plates and this affects their ability to recharge. Lithium batteries don't seem to have this effect to the same degree, but do eventually "age" as in this article (see link below). ----------------------------------------------------------------------------------------------- The short answer is yes, batteries like almost everything else have a limited lifespan. Different batteries have different lifespans and care instructions, so pay attention and choose a battery product with the best lifespan where it matters.

It sounds like your batteries won't hold their charge and need replacing, but before you do that, discharge them completely , for example by putting them in a torch with a bulb and then leaving it on until they are flat. (I am assuming you are using AA batteries). Then recharge them and see if it is any better. If not, get new ones - I would suggest you buy "Eneloop" brand AA batteries as they are very low-discharge : standard NMH rechargeables batteries lose their charge in a month when they are not even in the camera, unless you keep them in a cool place such as in the butter compartment in the refrigerator. Try it out.

It is wise to let batteries - whether in a cell phone or laptop - to run all the way down from time to time. Continuously charging your phone or computer can cause batteries to swell and lose their ability to hold a charge for long periods of time.

NO, putting batteries in the freezer will not charge them. For alkaline batteries (the most common kind of household battery), putting them in the freezer will extend their shelf life by less than 5%. And cold batteries can't be used immediately -- you have to wait until they've warmed up to room temperature first. If you need those batteries for a flashlight in an emergency, this could prove problematic. When stored at room temperature, alkaline batteries retain 90% of their power, and the average shelf life of alkaline batteries is five to seven years. For NiMH and Nicad batteries (often used for electronics), storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. Battery manufacturers tend to agree. Kodak says "refrigeration is not necessary, nor is it recommended" and "freezing is not recommended" for its alkaline batteries. Duracell advises: "Do not refrigerate Duracell batteries. This will not make them last longer." Both recommend storing batteries in a cool, dry place.

Atoms that lose electrons and have a positive charge become positively charge ions known as cations. All metal atoms can form cations.

Lithium batteries are composed of pure lithium in its metal form and are generally meant for one-time usage; they cannot be recharged. Lithium ion batteries, on the other hand, contain electrolytes of the lithium ion; these can be discharged and recharged many times. The lithium ion batteries have several advantages over other rechargeable batteries. For one, they're smaller in size and also have high voltage so that fewer cells are needed. Secondly, when idle, they lose charge at a slower rate compared to the other batteries, and hence are long-standing once fully charged.

you can't lose protons in an atom as they are tightlly bound to the neutrons in the nucleus, You can lose and gain electrons which changes the charge of the atom. If you gain electrons, then you have a negative charge, and if you lose electrons then you will have a positive charge.

i read of wikipedia that in a years time they can lose around 8-20% charge in a years time. i would recommend storing in a cool dry place to slow the draining process.
