4 Key Qualities of “The Best 21700 Battery”
Here are 4 important factors you need to know and pay attention to when picking the 21700 battery in particular and the vape batteries in general.
1. High Current Handling
The current rating is measured by amps. In easier words, it shows how fast the energy runs between two points of the circuit.
You may think the higher the amps are, the better the battery is. Sometimes, it’s true. But sometimes, it is the opposite because current handling is the only factor that affects the batteries’ performance.
Let’s imagine the 21700 as a bottle filled with water. The amps are the bottle opening. The bigger the opening is, the quicker the water runs out.
Hence, it would help if you charged the battery more often, leading to shortening its life expectancy.
To choose the best 21700 cells for your need, you should use Ohm’s Law, which relates to the voltage and the battery’s resistance. In a nutshell, you need to apply the formula below:
I = V/R
Among them: I is the current, V stands for Volts, and R stands for resistance.
2. High mAh Rating
mAh rating or the capacity of the battery shows how fast the energy will be cut-off from 100% to 0%. Following this concept, 4000 mAh cells can work twice as long as 2000 mAh cells in the same conditioner of usage.
You absolutely expect to use your vape devices as long as possible, and you think the higher mAh rating refers to a better product.
In this case, come back to the example of the bottle above. You will have your own answer.
3. High Voltage When Vaping
High voltage is what you can desire from the 21700 battery thanks to its bigger capacity.
From the Ohm’s Law formula above, higher Volts result in higher Amps. So, this is a big factor you need to consider before buying vape batteries.
4. Low Temperature Required
The heat that a battery requires implies how long it will last. If it’s hot, the battery tends to get a shorter lifespan, and in reverse.
Since the battery gets heated while using, it also burns up when charging. This is a big problem causing the explosion. So dangerous, right?
2 Rules for Smart Shoppers When Buying the Best 21700 Battery
Rule 1: Check the Figure of the Batteries
As we analyzed above, the figures of a battery are of importance. Hence, you need to read about it carefully.
Obviously, many products in the market have the same dimensions and statistics.
Which one is the best? Should you choose the more famous brand in this circumstance?
Rule number 2 will give you the answer.
Rule 2: Visit Battery Mooch for the Advice
If you are a beginner, Battery Mooch (also known as Mooch) sounds strange to you.
