What Are the Factors to Consider Before Buying the Best Batteries for Vaping?

1. Capacity

Before you can pay for the best vape battery, you need to be sure that the battery’s capacity will last you long enough; you don’t want a battery that’ll need to be disposed of in a week or so. Capacity is calculated in milliampere-hours (mAh), and it signifies the running time. One mAh equals the charge transferred by a stable current of one milliampere flowing for 60 minutes. Though this rating is occasionally overstated oncell wraps, this does not happen as frequently as it does with discharge ratings.

Besides, going over the ratings of trusted manufacturers, you’ll notice a pattern: there is always a trade-off between capacity and CDR. For example, there is no 18650 with a CDR over 30 amps. Concurrently, no 18650 with a capacity over or at 3000 mAh will have a CDR over 20 amps. Therefore, any battery not rated according to these thumb rules can be assumed to be falsely rated.

When buying the best 18650 batteries, try to avoid rewraps since the batteries used for them might change at any given time. Besides, with 18650s batteries being readily available, finding a battery from a trusted manufacturer should be a priority too.

2. Continuous Discharge Rating (CDR)

Continuous discharge rating means the maximum current that a battery can discharge safely and continuously without reducing its capacity or taking damage. So, when buying the best 18650 battery, remember to consider these ratings. A high discharge rating is very crucial if you want to use it with a low-ohm device. For instance, imagine you have a bottle full of water; the bottle size would be the battery capacity, while the opening level of water would be the maximum discharge rating.

As we mentioned earlier, the CDR is used by trusted electronic manufacturers. Therefore, it’s an important factor to compare battery discharge. However, some manufacturers will sometimes overstate the CDR or even use other ratings. For example, the rating on the wrap might be the maximum current that a battery can discharge in short intervals, which isn’t the actual CDR of the battery. Therefore when buying the best 18650 batteries, don’t just look for the CDR since it can be misleading sometimes.

3. Flat top and button top 

Another factor to consider before buying your best vape battery is whether you need a button-top battery or a flat-top battery. This feature refers to the positive end of the battery. As the name implies, a flat-top is a flat battery surface and may seem too short if your vape mod requires a button-top battery. Conversely, a button-top battery has a protruding surface that enhances the battery’s length and might not fit in a vape mod or pen that requires a flat-top battery.

4. Voltage

“Hitting harder” in a battery usually refer to the voltage at which the battery can withstand midway through its cycle, also referred to as voltage sag. For example, some vape batteries can remain around 3.7V midway throughout the cycle, while others drop to 3.2V or lower when drawing power, resulting in sag in power.

5. Operating temperature

When hunting for the best 18650 batteries, it’s wise to check the battery’s operating temperature. However, it’s hard to recommend which operating temperature is suitable for your 18650 cells. This is because the battery emits heat itself, and the surrounding temperature must be considered. When 18650 batteries usually generate heat which has an impact on the battery performance. Besides, overheating batteries always have less lifespan.

If your battery is steadily getting hot, this is a warning sign that you might be pushing the battery too hard. A battery that’s consistently rising past 45C has a shorter lifespan than a cool running battery. Besides, they can be dangerous as the potential for bursting increases greatly with a high-temperature lithium-Ion battery. We recommend you choose a battery with a higher CDR rating.

6. Manufacturer or brand

When choosing the best vape battery, you will realize that considering the manufacturer or brand is important as considering the CDR of the battery. As we mentioned earlier, not all brands are made equal, and regularly, you’ll find some of the manufacturers are not trustworthy in their battery ratings. The main goal of any manufacturer or brand is to sell as tons of batteries as possible; however, some companies have been known to overstate their ratings to appear to provide a better product than others.

Fortunately, the battery mooch, the watchdog team in the lithium-on industry, usually offers thorough testing and exposes these companies for their illegal practice. There are five main brands and manufacturers that you can rely on to offer quality, consistent and trustworthy batteries. Those brands are; Samsung, Molicel, Sony/Murata, LG Chem, and Panasonic/Sanyo. Fortunately, you’ll regularly see the best vape battery outdo the manufactures ratings claimed by these brands.
