18650 Battery Charger Review-Introduction, Inventor, And Working
As the lithium-ion batteries have revolutionized the world of portable power delivery with their amazing features. Charging them is another thing of major concern. The 18650 battery is the most popular type of lithium-ion battery.
Here we will discuss the charging methods of the 198650 battery along with the best chargers, the companies making the good chargers, and the working of a good charger.
What is the best 18650 battery charger
As the 18650 batteries are very popular in the whole world because of their vast number of applications. Many companies are producing accessories for the 18650 batteries. One of the most demanded accessories for these batteries is the charger. But the problem is that many manufacturers in the world are making chargers.
Some of them are good but some of them are no good. Here we will tell you about the characteristics of a best 18650 battery charger.
Overcharging Protection Circuit
The most important quality in a charger is that it must have a built-in charging protection circuit. The job of this circuit is to prevent the batteries from overcharging. Many lithium-ion batteries have a built-in charging protection circuit. But the size and form factor of the 18650 batteries does not allow it to fit a charging protection circuit.
Due to this reason, it is very important to get a charger that has a charging protection circuit in it.
One good feature that most chargers lack these days is the ability to charge the batteries in a short time. The batteries support this feature to be charged in a short time. But the chargers are not good enough. So, the charger that you get must support fast charging functionality because it can save you a lot of time.
Informs About The Bad Batteries
A good charger is the one that has a protection circuit in it. The protection circuit not only protects batteries from overcharging, but it also helps us to know about the bad batteries. When we place a bad battery in the charger, it draws more current than the good batteries.
The charger must not support charging bad batteries because they can be very dangerous if they explode.
Preserve The Quality of Your Battery
This is another property that is lacked by most chargers. A good charger must take care of the battery and its needs. As the battery is charging, its need for voltage, and current changes, a charger must be intelligent enough to sense this change in requirements of the battery and set the values according to the needs of the battery. Doing this will effectively increase the life of your battery.
Who makes the best charger
These are some of the best companies that provide the 18650 battery chargers in the market. The features of the chargers are also discussed below:
Nitecore Intelligent Charger
This is a charger that can charge 2 batteries at a time. The charger is made to charge AA, AAA, and 18650 size lithium-ion batteries. These are some features of this charger.
It intelligently detects the type of battery inserted and accordingly charges it.
Both the batteries inserted are monitored separately to provide the best charging for both of them.
There are colored led displays that tell you about the different stats related to both the charging of the batteries.
You can charge one or two batteries at a time according to your needs.
It shows charging of the battery by 2 led displays, one for each battery.
These were some features of this antilight charger.
Basen Smart Charger
This is another charger that can intelligently charge up to 4 batteries at a single time. The batteries supported by this charger make a long list. In short, we can say that it can charge more than 15 different types of batteries. These are some of the features of this charger:
It can intelligently charge the batteries by detecting the type and size of the battery.
It can charge 1 to 4 batteries at once.
All the batteries are separately monitored which means that you can insert different batteries and it will be no problem.
There is a built-in protection circuit that works on many different principles to protect your batteries.
How does 18650-battery charger work
The working of 18650-battery charger requires many different components to work. All of these works together to provide you with a seamless experience. Following are the working components on 18650-battery charger:
Voltage reducing unit.
Power conveying circuit.
The working of each of them are discussed below:
Voltage Reducing Unit
The 18650-battery charger works on the main voltage that is not good for the 18650 batteries. This is the reason the first working component of a charger is the voltage reducer. Mostly it is a small transformer that reduces the main voltage. This voltage is reduced so that it can be suitable for the circuits of the charger.
Power Conveying Circuit
When the voltage is reduced into a suitable amount for being used by the circuits, then it is passed to the circuits of the charger. The first component of this circuit is a rectifier that converts AC. into DC. This is because of the following things:
1.working with DC. is very easy as compared to AC.
2.Most circuits work on DC.
3.Batteries also require DC.
4.It is safe to work with.
When AC. is converted to DC, then the current is passed to the further circuits that are in contact with the battery.
This circuit can be called the brains of the charger. This is responsible for the efficient charging process of a charger. This circuit provides the current and voltage required by the battery intelligently to the battery. It also cuts the power off from the battery when it feels that the battery is fully charged.
This is a set of lights that tell about the percentage of the batteries while charging. Some chargers have 3 to 5 led displays to tell the charging of the battery. Some have 7 segment led displays to show the actual percentage of the battery.
This was all about the review of the 18650 battery chargers and their working.
