How to Charge Lithium Ion Battery Without Charger
There has been a rise in the use of lithium-ion batteries in mobile phones, laptops, and other electronic gadgets.
Lighter weight, higher energy density, and no memory effect are just a few of the ways in which these batteries excel above their lead-acid and nickel-cadmium counterparts.
There is, however, one significant drawback to lithium-ion batteries: you need a unique charger for them.
It is not possible to charge a lithium-ion battery with an ordinary AC adaptor, as is the case with lead-acid or nickel-cadmium batteries.
Don't freak out if you forget to bring the charger for your lithium-ion battery; you still have options.
Charging a lithium-ion battery without a charger can be done in a few different ways.
First, though, you should know how lithium-ion batteries function and why you have to be so careful when charging them.
Why does lithium-ion battery charge vary?
There is a wide range of charge voltages for lithium-ion batteries. As a general rule, charging rates for batteries improve with increasing voltage. However, the charging rate of a battery can also be affected by things like the battery's kind, the charger's quality, and even the weather.
A higher-voltage charger is likely to charge your lithium-ion battery more quickly than a lower-voltage one. Of course, you should check the battery's manual just to be sure; some batteries aren't designed to be charged with high voltage.
Can I charge a lithium battery with a normal charger?
Yes! You can use your usual charger (a lead-acid charger) to charge lithium batteries if it has a maximum voltage setting and no automatic equalization mode.
If you want to get the most out of your lithium battery, and make it last as long as possible, you should use a battery charger that has been optimized for lithium batteries.
How Does a Lithium-Ion Battery Charger Differ from a NiCad Battery Charger?
There are significant differences between Nickel Cadmium battery/cell chargers and Lithium-Ion battery/cell chargers.
LiIon cells have a voltage of 3.7 volts, while NiCads have just 1.2 volts.
Charging currents also vary between the two methods.
Lithium-ion battery chargers often include a more complex current-limiting circuit than NiCad chargers due to the higher risk of fire with defective or overcharged Li-ion cells.

2.Battery Recharging Utilizing Solar Energy
People that spend a lot of time outside, such as camping and hiking, may find a solar panel charger to be useful. You only need a solar panel (which can be found at any local electronics retailer), a USB cable, and (optionally) a battery pack.
Connect your solar panel and battery pack through USB to verify that they can exchange energy. Then, before you go, fasten it to your bags so that your gear may be charged as you go. The solar panel can be detached and the USB cable used to charge the device at night. This is a critical procedure when learning how to charge a li-ion battery without a charger.
3.Powering up with an AC adapter
A lithium-ion battery doesn't require a charger if your gadget has an AC adaptor. Before putting the adapter into your device, make sure the voltage restrictions have been adjusted.
You'll need to select an AC adapter that works with the voltage in your country, as most of them are rated for 100-240 VAC.
Look for a switch or knob next to the adapter's output port and turn it to the desired voltage setting. After that, all you have to do to charge your device is plug in the adapter.
4.Connect via the metal terminal contacts and the inside battery case wall.
Cleaning the metal contacts on the positive and negative terminals of the battery and inside the battery casing may restore power to a low-battery smartphone or laptop. This little step might assist guarantee a solid connection between your smartphone and battery for a more efficient charging.
First, remove any dust or debris from the contacts using a cotton swab or soft cloth. The battery terminals can be cleaned of corrosion buildup with a toothbrush or equivalent equipment. Reconnect the smartphone to its charger after cleaning its contacts.
5.Battery-Powered Recharging
Can a lithium-ion battery be charged in any other way other using a charger (10, 11)? Try to relax.
Another reasonable option arises while you are behind the wheel of your car.
You may speedily recharge your battery by using the power from your car's battery.
How? A child could do it.
You may charge the battery by connecting it to the terminals of your car's lead-acid battery.
