Types of 18650 Battery
There are two main categories for 18650 batteries, protected 18650 batteries and unprotected 18650 batteries.
Protected 18650 battery
A protected 18650 battery is a type of 18650 battery that has an integrated protection circuit module (PCM) to prevent the battery from overcharging, over-discharging, and short-circuiting. This protection circuit module is designed to monitor the voltage and current of the battery and cut off the power if the voltage or current exceeds a safe limit.
Protected 18650 batteries are commonly used in high-power applications, such as flashlights, power tools, and electronic devices, where the risk of overcharging or over-discharging can be a safety hazard. The protection circuit module helps to prevent the battery from becoming damaged or overheating, which can lead to failure or malfunction.
While protected 18650 batteries offer an extra layer of safety, they may also have some drawbacks. The protection circuit module can add some extra weight and size to the battery, which may not be suitable for some applications. Additionally, the protection circuit can limit the maximum discharge rate and reduce the overall capacity of the battery.
It is important to note that not all 18650 batteries are protected, and it is essential to check the manufacturer's specifications to ensure that you are using the appropriate type of battery for your device.
Why the protected battery is the safer option
This circuit protects against:
Excessive dangerous charging and discharging
Circuit breaks
Extreme temperatures
It is designed to protect the dispositive where we use these type of batteries and prevent damage from possible explosion or leakage.
Protected USB 18650 battery
Within the protected 18650 batteries you can find the protected with USB. This one makes you easier to charge the battery without the need of a battery charger. On the other hand, you must to be careful because sometimes are a little longer and sometimes it doesn't fit in your device.
Unprotected 18650 battery
Secondly, we have the unprotected 18650 batteries, these rechargeable unprotected batteries use to be a bit unsafe because do not have this internal circuitry as the protected batteries.
An unprotected 18650 battery is a type of 18650 battery that does not have an integrated protection circuit module (PCM). Unlike protected 18650 batteries, unprotected batteries do not have any safety mechanisms built-in to prevent overcharging, over-discharging, or short-circuiting.
Unprotected 18650 batteries are commonly used in applications that do not require high levels of safety, such as in low-power devices like remote controls, toys, and clocks. They may also be used in applications where the device has its own safety mechanisms to prevent overcharging or over-discharging of the battery.
While unprotected 18650 batteries do not have the extra weight and size of a protection circuit, they can be potentially dangerous if not handled properly. Overcharging, over-discharging, or short-circuiting an unprotected battery can lead to overheating, venting, or even explosion. Therefore, it is crucial to use an appropriate charger and follow the manufacturer's instructions when handling unprotected batteries.
