18650s are currently ruling the entire electronics market and are available quite bulk in
numbers. We will focus on all the aspects in this article why you need to buy 18650 batteries
and how they can be useful to you.
What are 18650 batteries?
An 18650 is a type of Li-Ion Battery which can be recharged at any given time. You can use the
same battery again and again just by recharging it, which means you can avoid the cost of
buying a new one. The actual name is called as “18650 cells” and carries about 3.7 volts of
current in it. It is determined to range between 1800mAh to about 3500mAh in amperes.
There are two different varieties of batteries i.e. one is protected, while the other one is
unprotected. We would recommend you if you are buying 18650 cells, then go for the
protected ones. The average charge time that every 18650 cells possess is approximately 4
hours. The usual charge time varies with the amperage and the voltage of the type of charger
you are using and the type of the battery. There are lots of 18650 Cell Manufacturers in India
that you can get in touch with to know about the quality of the charger you should be using.
You can also contact the li ion battery manufacturers in India to know more about it.
The usual sizes of the batteries range between 1100 to about 1170 cubic millimeters. If you are
opting for the usual size, make sure it can be used in your AA devices as it supports mostly 3.7-
or 1.5-volts batteries.
What is protected and unprotected 18650 batteries mean?
18650 batteries that are protected usually have a circuit. The cell packaging has the circuit
embedded in it which prevents the cells from getting overcharged or overheated, which may
end up in getting a short circuit. A protected battery is determined to be safer than that of the
unprotected ones mitigating a lot of risks involved in it.
Unprotected batters are quite cheaper when compared to the protected ones, however, the
risk percentage in using the unprotected ones are significantly high as well. If you are
externally monitoring the charge and controlling the amount of electricity that passes through
the circuit, then using unprotected 18650 batteries would be efficient. It consists of a button
top, but you need to check the specifications before buying it. The unprotected ones can easily
get overheated and overcharged if you didn’t monitor it properly. The vulnerability is generally
high in the unprotected cells as it doesn’t have a circuit embedded in it that stabilizes the
electricity. You can contact any Li-Ion Battery Pack Manufacturers to gather more details
about it before opting for it.
Both the types of 18650 batteries are capable of storing about 2 aH of electricity and to a
maximum of about 3.5 aH. It has the capability to store 10 to about 13-watt-hours if you are
considering the time factor. The Batteries can be recharged about 1000 to a maximum of
about 2000 times before disposing of it, which means it can last for a long period of time.
