Hello my name is Wilson Garcia I am new to the steemit community this is my second post, today I am going to talk about how to revive batteries of cameras and mobile phones, especially mobile phones, as you can see for almost 20 years the technology envelops us all, in an accelerated way, with intelligent equipment even faster than the PCs or laptops that we currently use, and many computers have the internal batteries of Lithium-lon, but there are also current equipment such as video cameras, DS , Ext that use removable batteries that also for some reason we keep and at the moment that we want to use them they do not work and that happens very often, the point is that these can also be revived.
And now I explain. The current phone chargers are usually separated Data Cable and USB Charger, and use a voltage of 5v and 1a, and the previous ones from 3.0v to 9v voltage.
To be able to revive a battery of these devices it is necessary to have the following tools:
1- Wire cutting pliers
2- Voltmeter.
3- Phone charger, it does not matter the brand, only the voltage of the charger, it is important that it does not pass more than 9 Volts, because the battery is burned, to identify these chargers it is necessary to verify them by the charger label or legend thereof.
It is not necessary to have high-grade knowledge to do this, nor the exaggerated voltage of live current like 110 or 220.
It is important not to cross the cables between them as it can cause a short and burn the charger.
Important: if you do not have to know which is the positive and negative cable, you can identify it in the following way, the positive cable is identified with a white stripe

The batteries are usually identified by the symbol of positive (+) and (-).

Only the positive cable of the charger and the negative one must be placed in the battery, for a time of 18 seconds counted, this merits two charges of the same time, that is to say the first charge of 18 seconds a pause of one minute and then another charge of 18 seconds, once the two sessions have been done, you must place the phone or equipment to be charged normally during the time required, that is, the normal way in which the device is charged.
(And ready to test your batteries again)
