How to charge a dead battery using another phone

There are situations when the charger for your phone is broken, and you urgently need to charge your device. But don't despair. If you do not live alone, then the problem can be easily solved. Any other phone of your family member will be suitable for charging the battery. However, you need to make sure that the voltage on the batteries from both phones is the same.

We will need

• 1. Battery from your phone.
  
• 2. Two wires with “crocodiles” soldered to them. Or any other clamps.
  
• 3. Elastic band.
  
• 4. Match.
  
• 5. A phone through which we will charge the battery.
  
• 6. The top part is from a universal charger (if available).

Charge the battery using another phone

So let's get started. If you don’t have a non-working universal charger, then we’ll use a match and an elastic band. Take the battery and connect the wires. They must be connected to the plus and minus of the battery. At the same time, do not forget about polarity.

We fix all this with a match and tighten it with several turns of elastic. In this case, you need to be careful not to short-circuit the wires. This may damage the battery.

If you have a non-working universal charger, you can directly connect the wires to the top cover.

We insert the battery, having previously remembered the connection of the plus and minus.

Then we take the battery from the connected phone. We remember the polarity on it. We connect our battery, simulating the original battery of the device. Plus to plus, minus to minus.

After that, we connect the phone and charge our battery.

Or like this:

In this way you can charge batteries from different devices. You just need to make sure that the voltage on the batteries is identical.
