Using power adapter: How do I manually charge my laptop battery?

This is a radical method to charge a laptop battery without inserting it into the laptop, which requires special tools:

  • The adapter itself with a voltage higher than the battery voltage;
  • Multimeter;
  • copper wires (several pieces).

Additional parts will also be required: for example, electrical tape or tape, a soldering iron.

Step-by-step instructions on how to charge a laptop battery without charger:

  • Take the battery and inspect the contacts (the number of terminals can exceed 7 pieces, this is normal);
  • Determine the polarity (in the absence of the necessary information, use a multimeter);
  • The terminals are connected to the wiring, having previously cleaned the ends of the latter, in order to secure more securely, use adhesive tape.

The preparatory measures have been completed and then it is possible to proceed using a conventional adapter. Attach the wires to the pins on the input connector. The scheme always works here, according to which the middle segment corresponds to the “plus”, and the extreme “minus”.

This is the most common way to charge your laptop battery directly.

Connect the plug from the power supply. Charging started.

This option is even more radical and requires experience in handling electrics. It will take some soft copper wires, an adapter with enough power. Its minimum voltage must match that of a standard adapter.

Before charging, inspect the plug socket. It is usually round. Connect the prepared wires to the contacts on the input connector. The polarity on all models of laptops is the same: in the center “+”, from the edge “-“. The neutral line often runs along the edge.

For a stronger fixation, the positive pole is wrapped with electrical tape or tape. The negative edge is secured as well. The wire should only touch the metal edge.

Attention! With the help of a multimeter, the intersections of the contacts are detected.

After connecting the wires, go to the power supply. The “minus” side intersects with the framing of the power supply output part.

Using an external power supply without a plug:

  • The contacts are bonded to each other taking into account the polarity;
  • Isolate contact points to avoid short circuit;
  • The power supply is charged;
  • Check the performance of the resulting circuit.

If the power of the selected adapter exceeds that of the original one, proceed carefully so that neither the PC nor the batteries overheat.

After completing all the steps, install the battery in the laptop until it is fully loaded.
