How To Charge New Li-Ion Battery?

Li-ion batteries are very popular all over the world because of its great use. You can easily see them in devices such as mobile phones, handheld drills, laptop, flashlight …

However, this is a chemical battery. It is not like the traditional batteries. So, charging a new Li-Ion battery is also very different.

In today’s post, I will show you some tips for charging new Li-Ion batteries in the right way! Roll down to read more!

1. Use the genuine charger that came with the device

You should charge the new Li-Ion battery with the charger that came with the device. Because the power parameters on the battery will match the device’s design.

 If the charger is damaged or lost, you should only use replacement accessories that have the same characteristics as your old product.

 If the charger fails, the charging time will be longer, the battery life will be shorter, and the battery will hot. When it is hot will lead to many dangers.

Note: you should not charge the battery through the computer or laptop. Because this way will cause the battery to be pressured by high temperatures due to lack of amperage. It will reduce the capacity of Li-Ion batteries.

Important: when the Li-Ion battery is full, you should wait about 5 to 10 minutes to remove it from the charger. This action will make the battery more stable for a long time.

2. At the first charge, charge when the Li-Ion battery is in a weak state

When you first buy a Li-Ion battery, you should use the remaining battery power. When the Li-Ion battery is weak, you will connect to the charger.

Do not leave the battery completely empty at the first charge. When the battery collapses, it will be very difficult to receive energy, and charging will take longer.

You should charge the Li-Ion battery for a short time, and charge it regularly. Li-ion batteries do not have a memory feature.

Charging when the battery is not in a weak state only affects the capacity measurement. But you can adjust it by charging and discharging 100% capacity after a few months of use.

3. 40% – 85% is ideal for charging Li-Ion batteries

The Li-Ion battery should be charged within 40% – 85% (about 4V) and then stopped. Maintaining a voltage level below 4V will affect battery life well.

 Limit charging when the battery is full. This happens quite often for those who like to charge their phones all night. However, this is a habit that harms Li-Ion batteries.

Another common factor is temperature. Avoid storing and using Li-Ion batteries at high temperatures if you want it to work for a long time.

 The battery can lose up to 80% of the capacity if you use it at 60 degrees for about a year. And when you use a Li-Ion battery for a year at 25 degrees, it will lose 20% of the total capacity.

4. Do not let the battery drop below 20%

You should not let the Li-Ion battery drop below 20% continuously for a long time. Because 20% is dangerous for battery life.

You should limit battery usage while charging (for example, use your phone to play games, access websites, listen to music … when charging).

This will cause the battery to heat up. If this condition persists, it will lead to the device exploding because the temperature is too high. And it will seriously affect your body.

5. Avoid discharging the Li-Ion battery completely

It is not good to leave a new Li-Ion battery in full condition for a long time, but completely discharging the battery to 0% is even worse.

 Although you cannot fully discharge the battery because the Li-Ion battery is discharged to 0% there is still a small amount of electricity.

But discharging the battery to 0% means that some battery cells will no longer be able to charge. And this tip will be good for Li-Ion battery life.

To sum up

How you use and store your Li-Ion battery will affect its life. In this article, I have listed 5 useful tips for keeping your Li-Ion battery working longer, especially new Li-Ion batteries.
