These batteries provide performance of a lithium cell. They come in different capacities, ranging from 1800mAh to 3500mAh and a nominal voltage of 3.7V. You can find the in high-drain devices like laptops and power-banks where several of them are connected into battery packs.
Here are the features of a quality 18650;
Long battery life
The first and most important thing to look for in an 18650 is it life. As you many already know, lithium batteries loose power even when they are not in use. This means, their shelf life is the same as when you are using them. Consider a battery that can give you a longer life. In essence, this should be one that has recently left the manufacturer plant.
A quality battery is all about voltage. This is the power that will flow into and run your device. A quality 18650 battery should have a voltage of 3.7V. This is the nominal voltage. Some fake 18650 cannot reach even 2.0V. There are bad dealers who rebrand worn 18650 batteries and take them back to the market. Such batteries will be huge waste of your time and money. And that is why you need to understand how to measure voltage.
How big is the battery? This may determine how much power the battery will hold. The higher the capacity, the better the batteries. As stated above, even strong batteries like 18650 lose their ability to hold power with time. If you are no careful, you will buy one that has already lost this ability. Do not go for a battery just because they are new. Take one because they can serve you longer.

But there are a few things you should ask about to make your work of selecting easy. The first thing is to consider the continuous discharge rating (CDR). This is also called amperage capacity.
Electrical current in batteries is measured in amps (A). One of the biggest disadvantages of high batteries is overheating when this current is pulled from the battery. CDR is the rate at which this process takes place. To be on the safe side therefore, march the CDR of the 18650 you are buying with the draw of your device. That way you will find a battery that does not come with the risk of overheating.
It therefore means one has to be sure about the brand they are buying. Not all brands have the best features for batteries. They are not user-focused, which ends often ends up in disasters. But there are many others who have focused on offering only the best quality. Take your time to research and buy batteries from brands that can guarantee best performance and long life.
