Baterije u skrinju?!
Tekstic je na engleskom, al mislim da se svi donekle sluzimo istim.
- bilo je na njuzima.. pa reko evo c/p:
!!! ako netko isproba neka javi !!!
If the life of your mobile phone's battery is shortening Due to "memory effect" or aging, would you go and buy a new battery to replace it?
Next time when you encounter this situation, try saving your money. I will tell you a very effective method that you can try and see:
1. Wrap the battery up with newspapers, put it into a plastic bag and then into the freezer for three days (the newspapers will absorb the excessive moisture).
2. After three days, take out the battery and leave it in normal temperature for two days.
3. After two days, fully charge up the battery and put it into your mobile phone and see (this is estimated to be able to salvage about 80%-90%)
This information was provided by an engineer in a well-known battery factory.
The logic behind this this process is that dry cell batteries are based on containing several chemical compounds which react with each other to create compounds with lower electrical potencial producing movement of electrons (eletricity for those who didnt do phisics or chemisty), as anyone who's studied chemistry knows, chemicals will tend towards a state with less
energy, in rechargable batteries, the chemical reactions can be reversed by applying energy to the battery, creating a inverse electron flow,
now, the process isnt perfect, and some sideproducts are created, some inefficiency occures becuase of non perfect conditions for the reaction and other causes, aswell as applying current when the chemical reaction is incomplete on sime types of batteries (memory effect),
now, the idea behind this trick is to remove a large amount of energy from the battery to take it to a complete "uncharged" state, as in to reverte it to the original unreacted components, also hoping that the excessive removal of energy will allow the side products to break up to the original reactants.

Lijepo rečeno, ali veći problem kod novijih baterija stvaraju ciklusi punjenja i pražnjenja koji uništavaju strukturu baterije i broj kojih nije beskonačan nego memorijski efekt.

samo malo, po tome ispada da jednom napravljena baterija praktički može biti prepetuum mobile??

@whiteboy ne jer se uvijek kod pretvaranja kemijske u električnu energiju i obrnuto dio gubi u obliku topline. To je moguće smanjiti, ali ne do kraja.

Meni se ne isplati neku pivu držati na toplom samo zato jer baterija nije tip-top, a sada nemam lovu za veći frižider.:)

....ja stavio bateriju u frižider,a stara ju spohala.........:)
-
znači danas si ručao pohanu bateriju :D
-
...ne ,stavil sam ju u mob.......:)

no dobro.
sve u svemu, zvuči zanimljivo, tko voli nek izvoli
