How to Manually Charge Laptop Battery With External Battery Charger

First, you’ll need to find an external charger that works with your laptop.

Once you have the charger, plug it into an outlet and connect the charging cord to your laptop. Next, you’ll need to figure out how much charge the external battery charger can give. Most of the time, users can find this information on the charger or in the paperwork with it.

Now that you know how much charge the external battery charger can give, you’ll need to find out how much charge your laptop battery already has. Most laptops have a settings menu where you can find this kind of information. 

Once you know how much charge your laptop’s battery has, you can figure out how long it will take for the external charger to charge it fully. Set the charging mode to “high performance” if you want to charge your laptop as quickly as possible. 

This mode will charge your laptop faster, but it will also drain the external battery charger more quickly. You can also save charge in the external battery charger by setting the charging mode to “eco.”

Once you know which charging mode your laptop is in, you can start charging it by pressing the “charge” button on the external charger. Depending on the type of charger you have, the charging process may start when the charging light turns on.

It’s important to remember that you shouldn’t use your laptop while it’s charging from an external battery charger. This could hurt your laptop or shorten the life of the external battery charger. When your laptop is fully charged, you can take it off the charger and use it like you usually would.

The next step is to identify the positive and negative wires on the DC power supply. Typically, you may do this by examining the symbols on the DC power supply. Connect the positive wire to the positive terminal on the laptop battery and the negative wire to the negative terminal after identifying which wire is that one.

The DC power supply should now be turned on and configured to the proper voltage. The laptop battery will provide a listing of the voltage. The battery should start charging as soon as the DC power supply is turned on and optimized for the right voltage.

It’s easy to charge a laptop battery with a DC power supply, but you should exercise caution. Before attaching the DC power supply’s cables to the laptop battery, double-check their polarity to prevent the battery from being harmed.

By depressing the clasp or button that releases the battery from the laptop, you can take it out. Find the battery’s charging port once it has been removed. This often looks like a tiny circle with a circle icon next to it.

Utilizing the proper cable, attach the solar panel to the battery’s charging port. While other solar panels could need a different kind of wire, some may come with a cable made expressly for charging laptop batteries. A place where the solar panel will get direct sunlight should be chosen. 

This is usually outside, but you may also put it close to a window or another natural light source. At least 4-6 hours, or until the battery is fully charged, should be spent letting it charge. This may change based on the battery’s capacity, the solar panel’s power output, and the amount of sunlight.

Disconnect the solar panel from the battery once the battery has finished charging. Make sure the battery is positioned correctly in the laptop’s battery compartment before reinserting it.

Check the battery level on your laptop after turning it on to make sure it is charged. It is significant to remember that utilizing a solar panel to recharge a laptop battery can be slower than using a typical charging connection and power converter, and may not be as effective. 

The size of the battery, the solar panel’s power output, and the amount of sunlight available will all affect how long it takes to charge the battery. 

However, in emergency situations or when there are no other charging options available, using a solar panel can be a good solution.
