Charge the battery without a charger

Of course, you don't need a charger to charge a battery, you need direct current, the right voltage and amperage, this can also come from a few kilos of apples. You read that right, you can also generate electricity with fruit.

Basic information on charging batteries

On the charging socket, on the charger or on the battery pack there is usually information about the amperage and voltage with which you should charge the battery. You should adhere to this information. How you get the electricity for it is unimportant.

  • If you only have a source of power with a higher voltage or amperage, you run the risk of damaging the battery if you are unlucky enough to see it explode. If the voltage or current is too low, it either takes a long time or it does not work at all.
  • If you only know the strength of the battery, but not the recommended charging current, the voltage and current should be slightly higher than the values ​​of the battery, at 6 V this is 7.2 V.

Warning: Batteries that you charge in electronic devices, as is often the case with cell phones or cameras, should not be charged using other charging devices than those intended. Often there are special protective circuits on the storage devices that prevent the electronic components from being damaged.

Obtain power for charging without a charger

You need a DC power source. As mentioned, it doesn't matter what type it is. Possible power sources are:

Charging a 12V battery - information

The accumulator, actually accumulator, namely "collector", we encounter everywhere in the daily ...

  • The car's cigarette lighter supplies 12 V, and if you have a voltage converter, you can charge batteries from the power source.
  • Conventional batteries are usually very suitable for charging a rechargeable battery. A mignon cell, for example, has 1.5 V, a rechargeable battery 1.2 V, which is the ideal charging ratio. But it often makes more sense to use the battery in the device instead of the rechargeable battery.
  • Wall adapters are also a good source of power to replace a missing charger, but be sure to use one that provides DC power. You also need to know clearly where the plus and minus poles are.
  • By the way, you can actually generate electricity with apples, potatoes or other acids. Insert a copper plate and a zinc plate into the fruit. Between copper (+) and zinc (-) there is a voltage of approx. 0.99 V and a current of approx. 1.5 mA. To increase the voltage, you need to take several apples and connect the copper electrode of one apple to the zinc electrode of the other. In order to increase the amperage, you have to connect the resulting elements in parallel, i.e. connect the remaining individual copper and zinc electrodes to one another.

Connect the battery to the power source

  • You must connect the power source that you use to charge a battery with the positive pole to the positive pole of the battery.
  • Again, there can be a problem if the battery is left in a device for charging. You can of course get a suitable plug, but if you don't know exactly how to connect it to the power source, then you shouldn't.
  • Measuring strips with alligator clips are usually the best solution when you want to charge a battery, because you can simply clip them onto the poles.

 In an emergency, you can therefore charge a battery without a charger.
