have you ever had a dead battery in your cameraat just the moment when you need them most? worse still is a dead cell in an emergencysituation. and you can't always carry a charger with you. for those who like to (or need to)improvise, these recommendations may prove useful.method 1 using a battery to charge a batteryremove the battery from the device..
Android phone charger, you will need access to the connection pointson the battery. keep in mind that the battery is not intended to be accessed on certainmodels of cell phone, so know what can be done with the model you have. on most (butnot all) android and windows phones the back can be removed with the appropriate amountof pressure in just the right spot. do not
attempt this with most apple products.find some aa, aaa, or 9-volt batteries.. unlike the power that comes from the walloutlet (alternating current), the power in common household batteries is no differentfrom that used by your cell phone or camera battery. perhaps you are baffled that anyone wouldsuggest using one battery to charge another. maybe you were expecting some magic trickthat would allow you to add charge to your battery without having to find an alternatesource of electric power. in fact, that is not really possible. one of the fundamentallaws of physics (the law of conservation of energy/conservation of mass) makes clear thatyou can't get something for nothing. deal
with it.it is recommended that you charge your battery rather than attempt to hot wire your electronicdevice and use the alternative batteries directly. using the improper amount of amperage or voltagecan potentially damage complex circuitry, so such methods are obviously not worth therisk. identify the positive and negative connectorson each battery.. on the aas and other household batteries thesewill be clearly marked. for most cell phone batteries, the positive connector will bethe one closest to the edge, while the negative connector will usually be the one farthestfrom the edge (there may be three or four connectors, but the middle one or two areused for temperature regulation and other
functions).obtain two pieces of metal wire.. ideally, these will be covered in plasticinsulation except for exposed ends. tape or clamp the wires to the battery thatwill be providing a charge and the battery that requires a charge..these wires may get hot (though most likely they will not if you are doing it properly).it will also take quite a long time to transfer the charge. you don't want to be holding themthe whole time. if your are using aa and aaa batteries, youmay want to connect them to each other "in parallel" before attaching them to the batteryrequiring a charge. this means using wire to connect the negative side of all the smallbatteries to the negative connector on the
battery that needs a charge, and the samefor the positive side. after some time, the battery should be charged..keep in mind that it probably won't be fully charged, but you should have at least someuse of the device that you needed. method 2using the rubbing trick remove the battery from the electronic device..hold it in your hands. rub the battery hard by using both of yourhands to generate enough friction and heat.. continue to do this for 30 seconds to severalminutes. note: your battery is not actually being recharged.a number of internet commentators have suggested the rubbing the battery actually providesit with additional charge, perhaps from built
up static electricity. this interpretationis completely incorrect. lithium ion cells, like all true batteries,release electricity as a consequence of chemical reactions. as predicted in the arrhenius equation,these reactions become more more powerful
as temperatures increase. essentially, youare improving the conductivity of the battery by raising its temperature.place the battery back in the electronic device.. you may only have a few moments of batterylife, so make the most of them. thank you for watching!
