What is the origin of the phrase recharge my battery?
I imagine it started with rechargeable batteries and someone just personified the concept to include people needing energy.

The NiCad or nickel cadmiun battery develops a "memory" of its duty cycle (called - surprise! - "memory effect") if it is used in a "pattern" for a while. If, say, a 2-way radio is used only a few minutes a day over a number of days and then put back on a charger after each use, it will "remember" t…his. If an attempt is made to use the radio for more time, the batteries just "drop dead" and the radio is unusable. (MORE)
The two common rechargeable battery types are lithium and NiCad.One is called a lithium ion battery. The other is commonly called aNiCad battery, containing both nickel and cadmium.
A battery that can be refilled with the energy it has. If it is in a phone, when you charge your phone, you are recharging the battery in your phone.
You should send your rechargeable batteries, as any other batteries, to your local recycling site, probably run by your local council.
How to restore your rechargeable batteries . Note: Keep in mind that heat is not your friend. Lukewarm is OK, but if the batteries get any hotter, STOP what you are doing! I claim *no* responsibility. This information is for you to enhance your own knowledge. It is in no way a tutorial on how to …work with electronics.. You need a voltmeter for this.. Step 1: Determine what kind of battery you have. This usually does not require cracking open the case, but you will most likely have to in the later steps. Plastic outer cases, such as on laptops and camcorders usually have "protection circuitry" that blocks you from working with the battery.. Lithium-Ion / Lithium-Polymer (LiIon, LiPoly) . Nickel-Cadmium (NiCd, NiCad) . Nickel-Metal-Hydride (NiMH) -- Not sure. Solution 1 of Ni-Cad most likely won't work, but solution 2 could.. Lithium-based Rechargeable Batteries . Lithium battery behavior is poorly documented and very few people know about it, both because lithiums have excellent retention and life-span characteristics, and because the lithium protection circuit keeps the battery in good condition. (In most cases). Lithiums do have a memory effect, but it works entirely differently from a ni-cad 's. If you think about it like dirty water in a leaky tank, when you leave your Lithium alone for too long (a month or so), the dirt settles and the faucet begins to get clogged. There may be plenty of water there, but it doesn't come out very fast, which makes the circuitry think that the battery is low, even when it's not. This is called internal resistance. A battery that has been left at one state (fully charged, fully discharged) for a long time will show this effect.. In order to clear it up, you need to get the battery to deliver power. As the damaged battery drains, it's performance "unclogs" and the battery meter sometimes even thinks that the battery's charge is going up. Don't completely discharge -- just keep drawing power (quickly is better), and recharge it as normal.. Aside from having my hands on the physical battery, I've also had success with a Palm-Pilot with a built-in 3-year-old lithium battery that had been sitting for over a year.. Nickel Cadmium . If your batteries don't work at all , skip down to the next section.. Poor performance . It is common knowledge that Nickel Cadmium like full discharge/recharge cycles. The reason is that Nickel Cadmiums store their energy in crystal form. When it is charged, crystals are created. As the battery is discharged, the crystals shrink in size. When you charge the battery before most of the crystals are gone, it both creates small crystals and enlarges the old crystals. After a few half-discharge cycles like this, you can end up with many larger crystals and not very many small ones. The result is that the energy is still there, but there is less surface area (many small crystals have more surface area than a few large ones of the same mass), resulting in decreased output. You'll need to completely wear-down the larger crystals.. The problem is that modern electronics can't operate on just a few crystals that are slowly giving their power up, so the oversized crystals never go away.. Read and open the case: Nickel Cadmium batteries don't need protection circuits, so you might be able to do this without opening the case. It's not very likely to be a problem, but I would recommend opening the case anyways. Worry not, if your batteries are shot, what good is the case anyways? If you do fix it, a little glue (I recommend cyanoacrylate) ought to put it back together. Look on your case and determine the total capacity (mAh) and voltage (V). My laptop battery shows 11.1V, 3800mAh. If you don't see it written anywhere on the case, you may be able to calculate it.. Determine your resistor : You'll want to discharge the battery over about a 1 hour period. Since the capacity (3.8A, or 3800mAh for me) is expressed as amp-hours, it will be our draw-amperage . Calculate the size of your resistor with this formula: ohms = volts / amps . Go to Radio Shack or Digikey , or make your own and find the closest resistor to this value. It needs to handle a power (watts) of at LEAST battery volts (11.1V for me) multiplied by draw-amperage (3.8A for me) (11.1V * 3.8A = 42.18 watts). This is going to be a big resistor, and it will get hot when you're using it. Be sure that the batteries aren't getting hot. If you're comfortable dissipating more energy, you could discharge the battery much faster (at 4C, for example), or if you can't find a resistor that can handle the watts, you could try lowering your draw amperage and finding an appropriate resistor.. Connect the resistor: Connect the resistor across your battery pack (the pack itself; not the + and - output on the protection circuit), and a voltmeter (in parallel). Because of various voltage drops and anomalies I'm not going to go into, you may need to leave the battery discharging for more than an hour! You're not done until the voltage is very low (such as .1 volt per cell or lower) If you're also using an ammeter (in series), your measured amperage should drop as the voltage drops. If your resistor is adjustable, you can decrease the ohmage in order to keep the amperage the same, but you don't need to.. No Performance . Another problem Nickel Cadmium has is it can develop conductive fibers which short-out the battery. To get rid of these, they must be burned away with a high voltage source. To do this, you absolutely must open the battery case. You will have to zap each of the cells individually. You will also need a high-power source. A wall transformer rated for 2A or more at 3V to 6V volts may work, but I recommend a fully-charged battery, since they can really pack a punch. The total voltage for the source batteries should be 3V to 6V. Put the positive to the positive and the negative to the negative for about 3 seconds, for each cell. Charge the battery normally.. Calculating your capacity and voltage . Lithium batteries have 3.7 volts (nominal) per cell, Nickel-based batteries have 1.2 volts per cell. These voltages add-up when the batteries are in series (end-to end; the positive of one battery touches the negative of the next). The voltage does not change when the batteries are in parallel (positive on battery A touches positive on battery B, and negative on battery A touches negative on battery B). Capacity (mAh) works in the opposite way. When batteries are in parallel, the capacity adds up, when in series, the voltage adds up. Some battery configurations are set up in both parallel and series. Find the parallel batteries first, then treat them as a unit to calculate them in series next.. Making your own high-power resistor . You will need: Pencil lead (graphite), two wires, a tray of water, and ohm-meter.. Strip (1" or more) and wrap one wire to the end of your graphite so that it is snug and makes a good connection. Connect the other wire to the other end. Now measure the resistance (put each lead of your ohm-meter to the ends of your two wires). Slide the two wires wrapped around your graphite closer and farther until you read the right value (+-10% should be good). Since you'll be wasting a lot of power, you should break off the unused ends of the graphite and put it completely inside a tray of water can carry the heat away. It will bubble and fizz as it's being used; just don't let extremely large amounts of the fizz get to an open flame. (Ie. Don't collect/store the bubbles.). I recommend using a second amp-meter to monitor the quality of your custom resistor by putting it in series ( not parallel, it could blow your meter fuse, melt your battery or create pure lithium! ) with the resistor. When the circuit is connected, the ammeter should read about equal to your drawing-amps . (MORE)
They get recharged for another use! The electricity from the charge causes certain chemical reactions to take place which are in reverse of what happened as the battery drained. Then the process can happen all over again.
Cannot be given a specific answer - too many variables. What type battery components? Frequency of usage? Length of charge time(s)? How long on the charger? Number of cycles?
Batteries are charged with a higher potential than at which they operate. This higher charging voltage comes from a battery charger.
One of the best ways to recharge batteries is to do so only until the battery is fully charged. Most battery chargers will have indicator lights that let you know the batteries are ready. Remove the batteries from the charger instead of leaving them on for an extended period of time after charging i…s complete. Overcharging batteries will decrease their life. Plan ahead for an optimum time to charge batteries, and set a timer to remind you to take them off the charger. \n. \n. \nSome types of battery can be recharged (called secondary batteries). Others cannot (called primary batteries).\n. \nYou recharge a battery by connecting it to a power supply set to a higher voltage than the battery, usually through a current limiting resistor, connecting it to a special purpose power supply called a battery charger.\n. \nTo avoid damage to the battery, there are limits to how much current you can put into it, and this limit changes as the battery charges. These conditions are different for each type and size of battery. Consult the manufacturer of the battery if you need details.\n. \n. \nIf you are actually asking "How is it that batteries can be recharged?" that is a different question. simply, batteries generate current by way of chemical reactions that generate free electrons that constitute the electric current output. Secondary batteries have a type of chemical reaction that can be driven in the opposite direction by applying an external current.\n. \nThis article has lots more detail.\nhttp://en.wikipedia.org/wiki/Battery_%28electricity%29 (MORE)
Yes. Most ordinary "nonchargeable" batteries can very well be recharged a few times. Most alkaline and lithium batteries can be recharged from 3 to 10 times. Some lithium batteries even more. I have actually not experimented with other "nonchargeable" batteries. Problems: The problem wi…th recharging these types of batteries is that they are not designed to be recharged! It should be done slowly over long time rather than very fast like most chargers today does. You can not complain either if the batteries actually start leaking. They might even "violently" crack open (Explode) if you try to charge them with a lot of current. This so called "explosion" is however not an actual explosion. Using the word "Explosion" causes un-needed fear. What actually may happen is that the pressure inside the battery increases during the charging process. the sealing of the battery may rupture and some of its content, acid or alkaline, may be forcefully sprayed out. This of which is harmfull to skin, espechially eyes. Slow recharging ensures low pressure and less chance of seal breaking. My method and experiences.: I recharge my Alkaline and Lithium AA Batteries over a time of approx 16 hours. My battery charger is adjustable and can deliver 25-200 mA. When recharging slowly with only 50mA, the batteries keep quite well and can be recharged a few times. If recharging at 200 mA, they get warm (due to gas buildup and high pressure inside). This pressure causes batteries to crack open and leak. This mean that battery is forever dead. As of not exactly knowing the capacity of a nonchargeable battery, it is a bit difficult to give a time frame for recharging. We can however somewhat count on a capacity comparable to similar rechargeable NiMh batteries. These batteries today are close to 2000 MAh. Easy math tells us that recharging such a battery at only 50 mAH takes time. Straight forward, 40 hours, but taken into consideration the loss factor of charging (approx 40%), it would take close to 60 hours to fully recharge. If recharging at 100MAh this time would be halved to 30 Hours. My experience though is that when I try to recharge a battery for that long, it will start to leak, almost no matter what. I never charge my alkaline batteries for more than approx 15-20 hours at 50-75 MAh. This will of course not give a full charge but the batteries can withstand it better than a full charge. They last for ages afterwards in my mouse or keyboard. Note: My battery charger is full of corrosion due to battery-fluid from alkaline batteries. This mainly because I forget the batteries in there for too long a time, or try to recharge too many times. (MORE)

Yes but you'll have to find the recycling center in your area. It could be the company that handles solid waste for your community. If they don't they may know who does.
I could go on for days as I am an electrician but examples ofrechargeable batteries penis, vagina, pubes, anus etc
You recharge them. this requires a charger. some cameras and other digital equipment have the chargers and batteries built in.
rechargeable batteries last longer because you can charge them. if you get a non rechargeable battery then it will run out and then you have to waste money on getting new batteries.
A dry cell has the electrolyte immobilized as a paste, with only enough moisture in the paste to allow current to flow. As opposed to a wet cell, the battery can be operated in any random position, and will not spill its electrolyte if inverted. While a dry cell's electrolyte is not truly complete…ly free of moisture and must contain some moisture to function, it has the advantage of containing no sloshing liquid that might leak or drip out when inverted or handled roughly, making it highly suitable for small portable electric devices. By comparison, the first wet cells were typically fragile glass containers with lead rods hanging from the open top, and needed careful handling to avoid spillage. An inverted wet cell would leak, while a dry cell would not. Lead-acid batteries would not achieve the safety and portability of the dry cell, until the development of the gel battery. A common dry cell battery is the zinc-carbon battery, using a cell sometimes called the dry LeclanchÃ© cell, with a nominal voltage of 1.5 volts, the same nominal voltage as the alkaline battery (since both use the same zinc-manganese dioxide combination). The makeup of a standard dry cell is a zinc anode (negative pole), usually in the form of a cylindrical pot, with a carbon cathode (positive pole) in the form of a central rod. The electrolyte is ammonium chloride in the form of a paste next to the zinc anode. The remaining space between the electrolyte and carbon cathode is taken up by a second paste consisting of ammonium chloride and manganese dioxide, the latter acting as a depolarize. In some more modern types of so called 'high power' batteries, the ammonium chloride has been replaced by zinc chloride. (MORE)
Depends a bit on who you ask. Some - manufacturers of special chargers - will say that you can,at least a few times, if you use their chargers. OTOH, according to the manufacturers of "real" rechargeablebatteries, theirs are the only ones that can be recharged. People who have tried the special char…gers, and charging supposedlynon rechargeable batteries will usually tell you that it does work,but that you don't get much capacity, and you only get a fewcharges before they're entirely useless. Oh, and sometimes they leak/burst. And don't try charging non-rechargeable batteries in a regularcharger. That will almost always lead to the batteries leaking orbursting. (MORE)
Impossible test? Rephrase your question as it makes no sense. At leas not in the categories you listed this question in.
plug in your charger into your ipod or iphone and then plug in the other end to your computer
It depends what batteries they are. Answer: though the answer is it depends on the type of rechargeable battery, some battery can be recharged by applying electricity in the reverse direction of the regular uncharging. Other may be recharged by physically removing and refilling the chemicals. N…OO that would be bad! Lets say its a 12 volt car battery, what you would do is have a voltage higher than that, 14.4 is the best for a car battery. Now lets talk about household batteries like AAA, AA, C, D. You would charge those at 1.5 or 1.6. (MORE)

They must be replaced once you have used the non-rechareable batteries they Carnot be used again
They are in general, but this depends on the kind of battery. Household single-cell batteries (AA, AAA, etc.) vary case by case while other batteries designed specifically for electronic devices (laptop batteries, ipod batteries, etc.) are always rechargeable. Single-cell batteries such as AA… batteries are usually Alkaline and with the exception of a few rechargeable alkaline batteries, they are disposable. Constantly replacing batteries gets expensive over time, so rechargeable batteries are available. While they can cost 10 times more than disposable batteries, they last for hundreds of recharge cycles. With improving technology in battery technology, rechargeable household batteries these days typically do not require conditioning and can even be used straight out of the box, pre-charged. Basically, if your AAA or AA battery does not say "rechargeable" on it, do not try to charge it. Doing so can cause combustion or other severe damage. Batteries that are built to power specific devices are usually made of lithium cells and provide more power, always being rechargeable. While these batteries are more convenient, they are often impossible to replace and suffer from gradual capacity loss over a span of several years. (MORE)
Rechargeable batteries help the environment because instead of throwing away old batteries and filling up landfills and contaminating the ground with battery acid, you can use them again.
Rechargeable batteries are considered environmentally friendly because although they still contain metals and chemicals that are toxic, they are good for the environment compared to non-rechargeable batteries. Rechargeable batteries often last hundreds of times longer, meaning that less waste is pro…duced and less resources have to be used to replace them. Also, most other environmentally friendly devices such as solar panels require rechargeable batteries in order to function. Since solar energy is not available all the time (like at night) the power must be stored in a battery, which of course has to be rechargeable. "Environmentally friendly" cars such as hybrids and fully electrical cars rely on rechargeable batteries as an alternative to fossil fuels. Basically, rechargeable batteries cut down on waste and resources needed while making other environmentally friendly devices possible. (MORE)
Since there is claimed dangers in re-charging take your own risk to save a couple of dollars. Watch batteries are typically 1.5 v. Take an alkaline 1.5 v AA battery and use a copper wire.

No, a pack of AA rechargeable batteries are not expensive. A pack of four generally runs between 7 and 12 dollars and are manufactured by Energizer or Duracell.
Duracell offers good quality and easy to use rechargeable batteries. There are generic brands of rechargeable batteries out there but they are often unreliable and wear out very quickly.
Rechargeable batteries can range anywhere from $9 to $30 depending on the voltage and quantity of batteries. I find Duracell makes the most cost effective purchase for rechargeable batteries. Rechargeable batteries can last you about 2-3 years.
The rechargable batteries are easily available across the internet and on the high street. Once you have purchased them you will need to insert the batteries into the recharger and insert it into the power supply and allow to charge with the power on for the desired time for the for which ever batte…ry you are charging, this is because different size batteries can take longer to charge.

If yo uare tired of paying the high prices for batteries you may be wondering which companies sell rechargeable batteries. Rayovac, Duracell, and Energizer all sell rechargeable batteries.
Rechargeable batteries are special because they are specially made to do so. Batteries that are capable of recharging will be stated on the label (eg. duracell rechargeable) and are usually more expensive.
Why does your Panasonic phone tell you not to use 1.5v rechargeable batteries instead of their original 1.2v rechargeable battery?
Using standard cells with 1.5v nominal voltage, will take the total battery voltage too high and damage the circuits.
Yes. The 3DS has a rechargeable battery that will last between 3-8 hours depending on what games are being played, wireless communication and brightness settings. The system can either be charged via a DSi/DSi XL/3DS charging cable or with the included cradle.
You can use them over and over without spending gas and money in buying them at the store plus in a way you'll be recycling.
It comes from the coal, oil, or natural gas that are burned, or the uranium that's reacted, or the other batteries that are used, or the falling water that flows through the hydroelectric generator, or the kinetic energy in the wind that turns the windmill generator, or the solar radiation collected… by the photovoltaic cells, to generate the electric supply that's used to recharge them.

The same way rechargeable batteries workS. Anode, cathode, electrolyte, difference in charges, flow of electrons. The only difference is when you are done with non rechargable batteries, you throw them away.

Charging Ni-Cd batteries can be charged at several different rates, depending on how the cell was manufactured. The charge rate is measured based on the percentage of the amp-hour capacity the battery is fed as a steady current over the duration of the charge. Regardless of the charge speed, more e…nergy must be supplied to the battery than its actual capacity, to account for energy loss during charging, with faster charges being more efficient. For example, an "overnight" charge, might consist of supplying a current equals to one tenth the amperehour rating (C/10) for 14-16 hours; that is, a 100 mAh battery takes 10mA for 14 hours, for a total of 140 mAh to charge at this rate. At the rapid-charge rate, done at 100% of the rated capacity of the battery in 1 hour (1C), the battery holds roughly 80% of the charge, so a 100 mAh battery takes 120 mAh to charge (that is, approximately 1 hour and fifteen minutes). Some specialized batteries can be charged in as little as 10-15 minutes at a 4C or 6C charge rate, but this is very uncommon. It also exponentially increases the risk of the cells overheating and venting due to an internal overpressure condition: the cell's rate of temperature rise is governed by its internal resistance and the square of the charging rate. At a 4C rate, the amount of heat generated in the cell is sixteen times higher than the heat at the 1C rate. The downside to faster charging is the higher risk of overcharging, which can damage the battery.  and the increased temperatures the cell has to endure (which potentially shortens its life). The safe temperature range when in use is between â20Â°C and 45Â°C. During charging, the battery temperature typically stays low, around 0Â°C (the charging reaction absorbs heat), but as the battery nears full charge the temperature will rise to 45-50Â°C. Some battery chargers detect this temperature increase to cut off charging and prevent over-charging. When not under load or charge, a Ni-Cd battery will self-discharge approximately 10% per month at 20Â°C, ranging up to 20% per month at higher temperatures. It is possible to perform a trickle charge at current levels just high enough to offset this discharge rate; to keep a battery fully charged. However, if the battery is going to be stored unused for a long period of time, it should be discharged down to at most 40% of capacity (some manufacturers recommend fully discharging and even short-circuiting once fully discharged), and stored in a cool, dry environment. Charging method A Ni-Cd battery requires a charger with a slightly different voltage than for a lead-acid battery, especially if the battery has 11 or 12 cells. Also a charge termination method is needed if a fast charger is used. Often battery packs have a thermal cut-off inside that feeds back to the charger telling it to stop the charging once the battery has heated up and/or a voltage peaking sensing circuit. At room temperature during normal charge conditions the cell voltage increases from an initial 1.2 V to an end-point of about 1.45 V. The rate of rise increases markedly as the cell approaches full charge. The end-point voltage decreases slightly with increasing temperature. (MORE)
The function of rechargeable is that it can be used on numerous occasions at very little cost compared to using non rechargeable,which has a limited life span and not cost effective.
they can be recharged by hooking jumper cables from a car to the mower or if the battery is fried you would have to buy a new battery for it Use a battery charger just like the one you use on an auto battery.

Kinda-sorta. With the right kind of charger, regular batteries can be recharged to some degree. They won't hold as much charge and may overheat. And they'll hold less and less for each charge. Not many people find it worthwhile to do.
You can charge a battery 300 to 500 times. This will charge batteryto 80 to 100%.
