Can I charge the battery without a phone?

Is the miniUSB socket broken in the smartphone? Or do you have only a battery without a mobile device? Understand how to charge the phone battery without the phone. This can be done directly. But you must take precautions. So you keep the device in working condition. And you will use it even if the USB connector is broken.

You can charge the phone battery even without the phone itself. But risky!

What you need to know

IMPORTANT. “Extreme” charging hurts the gadget. It is simply not intended for such a connection. As a result, the device may fail. Better not to experiment. Do not do this just for fun.

If you are interested in how to charge a battery without a phone, due to the fact that it is broken, take it in for repair. It is better to fix the device, and not to damage the battery. The direct charge method is a temporary solution. It is suitable when you urgently need a “mobile phone”, and you cannot power it in the usual way. But you can not constantly charge the battery separately from the smartphone.

There is a safe alternative - the transfer of energy literally through the air. The technology has appeared recently, so the old smartphone models do not support it. For wireless recharging you need a set of equipment: a charger (source of electromagnetic signal) and a receiver, which is mounted on the phone's battery. The receiver itself may already be built into the gadget.

Technical progress allowed to charge the battery without cords and cables

This is not the best option, as charging a smartphone battery without a smartphone will not work. Yes, and it will be replenished slowly. But if the mini-USB slot just doesn't work for you, wireless power transmission will be easier and safer. With it, nothing will break or explode. Significant minus - the necessary equipment is expensive. Other methods, though risky, are available to everyone.

To decide how to charge the phone battery directly, you need to pull it out of the case. If it is not removable, it will not be possible to get to the contacts. And do not manually refill the battery while it is in the smartphone.

Universal charger

There is a universal battery charger for mobile devices. In the people it is called "Toad" or "Frog". If you put it on the table, it will really resemble this animal. The method is not so dangerous. But the battery can still break. It is better not to abuse them. And to replenish energy only when there is no other way out.

Here's how to charge a phone battery without a phone:

  1. Turn off the device and remove the battery from it.
  2. Find contacts on it - metal inserts, next to which there are symbols “+” (“Plus”) and “-” (“Minus”).
  3. Open the lid of the Frog. To do this, press your finger on its edge - it will rise.
  4. Inside there are two terminals.
  5. Further, it will be easy to figure out how to charge the battery without a phone directly. Insert the battery into the “frog charger” so that the two extreme contacts join the terminals. Look for coinciding "Pros" and "Cons".
  6. Close the lid. She will press and fix the device.
  7. Insert the charger into the outlet. The red light should turn on.
  8. If the light does not light up, then something is wrong. Try turning the phone battery over. Suddenly, "Pros and Cons" did not match.

A special gadget will allow LIA to charge separately from the phone

"Frog" is suitable for lithium-ion batteries. In the characteristics of the gadget should be specified "Lithium-Ion" or "Li-Ion". This is written on his body.

Directly

If the battery has contacts, then it is possible to lead the wire to them. But it is better not to do it alone. Call your partner to help him if you are electrocuted.

To charge the phone battery directly:

  1. Prepare a charger cable that you do not mind. Check in advance if it works.
  2. Cut the miniUSB plug from it.
  3. Carefully remove the insulation.
  4. Inside there will be two wiring - blue and red.
  5. Cut off some insulation from them too. Do not damage them.
  6. Remove the battery.
  7. Attach to her contacts exposed wiring. Blue is “Plus”, red “Minus”.
  8. Secure them with tape.
  9. You can connect to the mains.

Understanding how to charge the phone battery directly from charging is easy. But how not to spoil the battery? Such feeding is always a risk. Even if you do everything neatly.

Watch the temperature of the device. If it gets very hot, turn it off. But do not hold it in your hands. And do not touch the bare cord when current is applied to it.

When connecting the power supply wires to the battery, observe the polarity

How to check where is “Plus” and where is “Minus”?

If the cable has other colors, how to find out which one to attach to “Plus” and which one to “Minus”? After all, it is necessary to charge the battery. There is an interesting way. Let's make an experiment in physics.

  1. Dip the tips of the wires in a little salted water.
  2. Plug the charger into a power outlet. Do not touch bare cord and water.
  3. Bubbles will accumulate on one cable. This is a negative charge - "Minus".

From another battery

You can feed one gadget from another. The algorithm of actions is about the same as the previous chapter. Only instead of the outlet - batteries. Connect them with wire, fasten everything with scotch tape. And if in one of them there is more energy, the phone battery will start charging without a phone.

But here there are some rules. Batteries should have the same specifications: amperage, power, capacity. It is not as dangerous as feeding from the network. But there is a risk to break both devices at once.

If the connector on your phone does not work, you can charge its battery directly. Simply attach the cable to its pins. But do not do it for no reason. The battery may fail.
