When it comes to choosing the best 18650 battery, the most common question that everyone will properly themselves is what make a good 18650 battery. So in this post, we’ll look into some of the most important specs of an 18650 battery and help you decide exactly what you need from them. Without further ado, let’s take a look at our guide.
Through many examinations plus our personal experiences, we’ve decided there are four factors that you’ll need to consider when buying 18650 battery:
This factor is important since it shows that how long you can use your device. The capacity of the battery are measured in mAh (milliampere per hour). Like its name, it tells you how many energy can be drawn out of the battery within an hour. For example, your battery says “2500mAh” means that the battery could provide 2500mA in exactly one hour. Battery with higher capacity will have a higher amount of mAh. But sometimes, the number on the battery could be incorrect compared to its real power and the manufacturer could lie about it. So make sure to check your battery first and always buy your products from trusted brands.
It is important to find a battery with a proper current rating. Otherwise, it could cause serious problem to your device. The current must be stable and safe. This way, it’ll make sure your device working properly. And a safe current also makes the charging more comfortable.
Different device run with different voltage. And they all have their “comfort zone” that cover a certain range of voltage. Lower or higher voltage will cause the devices to stop function and even break. So be sure to check the battery specific information first before you buy it. Not all 18650s are the same though.
And last but not least, the battery temperature is something you need to pay attention to. The battery should maintain a comfortable temperature in use and when being charged. If your battery is heating up too much, you’d like to consider buying a new one because it is really dangerous. The battery could explode due to the uncontrollable heat and this also makes your battery become toxic.
