You may not want to resort to charging your battery without a charger but what happens when you are in an emergency situation or are camping in a remote area without access to a charger?

 

The good news is that there are ways to recharge your lithium-ion batteries without chargers. This may sound like an impossible feat, but it is possible!

 

Here is a compilation of ways to charge a 12 volt batteries without a charger.

 

  1. Use A USB Port

If you are using a USB port, you first need to make sure that the port is outputting at least 2 amps.

 

If it is, you can connect the USB end to any USB-capable device, such as your PC, desktop computer, camera, power bank, printer, or other electronic devices.

 

Connect the positive and negative wires from the USB cable to the corresponding posts on the battery.

 

  1. Solar Panel-Powered Battery Charging

A great source of DC power supply is solar panels, so if you are using a solar panel, connect the positive and negative leads from the panel to the corresponding posts on the battery.

 

However, due to the sun’s direction and warmth change, the output voltage usually fluctuates, making it unstable most times.

 

But you can control this by making sure the solar panel is receiving direct sunlight.

 

Also, it is highly recommended that you connect a charger controller to the solar charging system before using it to charge your battery.

 

If you don’t have a charger controller, look out for a rating of 12 volts on the solar panel so as to reduce its output voltage from 17 volts to 13 or15 volts. (Be sure to unplug your battery once it starts becoming too hot).

 

Once you have connected either your USB cable or solar panel, wait for the indicator light on the battery to turn green. This means that it is fully charged and ready for use.

 

  1. Charging From An AC Adapter

If your device has an AC adapter, you can use it to charge your lithium-ion battery without a charger. Just make sure to change the voltage limits on the adapter before plugging it into your device.

 

Most AC adapters are rated for 100-240 VAC, so you’ll need to find one that’s compatible with the voltage in your country.

 

To change the voltage setting on your adapter, locate the switch or knob near the output port and set it to the appropriate setting. Once you’ve done that, simply plug the adapter into your device and let it charge.

 

  1. Use The Metal Contacts On Your Terminals And On The Inside Wall Of Your Battery Case

If your phone or laptop is running low on battery power, you may be able to give it a boost by cleaning the metal contacts on the positive and negative terminals of the battery and inside the battery case. This simple procedure can help to ensure that your device is able to make a good connection with the battery, allowing it to charge more effectively.

 

To clean the contacts, start by using a cotton swab or soft cloth to wipe away any dirt or debris that may be present. If there is any built-up corrosion on the battery terminals, you can gently remove it with a toothbrush or similar tool. Once the contacts are clean, reconnect your device and try charging it again.
