The Wrong Question: Which Vape Battery is Best?
Asking which vaping battery is best is as silly as asking which car is the best. Automobiles come in all different shapes and sizes, each with its own specific utility. Comparing a fuel efficient sedan to a high torque truck is like comparing apples to oranges because they simply aren't used for the same thing.Vaping batteries are much the same, with each different battery type made specifically for a different type of application.
When it comes to batteries there are two factors you're going to want to consider: energy capacity and maximum continuous current. Measured in milliampere/hours (mAh), you can think of a battery's energy capacity like a tank full of water where a bigger tank holds more water. Having a higher maximum continuous current can be thought of like a large spigot that allows the water to be drained faster. The physical laws that govern battery construction, unfortunately, mean to get more of one you pretty much have to settle for less of another, meaning picking a battery comes down to a question of trade.
The Right Question: Which Battery is Best for What Application?
Since you have to trade maximum continuous discharge to get more capacity, and vice versa, the right question is not which battery is best but rather which battery is best for what I'm going to use it for. Generally speaking, the higher wattage you're vaping at, the more maximum continuous current you're going to need. If you're a low wattage flavour chaser, you can certainly vape safely on a high current battery, but since you aren't using it to anywhere near its full potential, you're going to be better off with a high capacity device that will last longer in between charges.
Batteries come in five classifications, ultra-high capacity, high capacity, medium capacity, high discharge, and ultra-high discharge. You can think of the ultra-high capacity as the fuel efficient little coupe and the ultra-high discharge as an eight cylinder truck. Just like you're not going to want to take a V8 truck on a road trip or try to pull a trailer with a sedan, you don't want to use the wrong battery in the wrong device. It's very important to take the time to research the battery requirements of the equipment you're vaping on and then find a battery that's properly suited for the type of work you're requiring from it.
Ultra-high Capacity: Capable of storing up to 3500mAh and handling a maximum continuous current of 10 amps or lower, these extremely long-lasting batteries are perfect for use with regulated mods below 30 watts and mechanical mods above 0.4 ohms.
High Capacity: Generally referring to a battery with a capacity around 3000mAh and a maximum continuous current of 15 amps, high capacity batteries are best when used on regulated box mods between 30 and 40 watts or mechanical type mods at a resistance range of 0.25 to 0.4 ohms.
Medium Capacity: The "middle of the road"type battery, medium capacity cells have around 2500mAh of charge capacity and support a maximum continuous current of 20 amps. Designed for use on regulated mods somewhere in the 40 to 60 watt range and mechanical mods between 0.19 and 0.26 ohms, these are the most common type of 18650 battery you'll likely see for sale.
High Discharge: High discharge batteries have a maximum capacity of around 2000mAh and are rated for 25 amps of maximum continuous discharge. Designed for use on regulated mods around between 60 and 120 watts or on mechanical mods at a resistance range of 0.15 to 0.18 ohms, high discharge batteries are the safest choice for all but the most serious of sub ohm cloud chasing rigs.
Ultra-High Discharge: Able to hold only 1500mAh of charge capacity but able to handle up to 30 amps of maximum continuous current discharge, ultra-high discharge batteries are the semi trucks of the vaping world. Designed for use in regulated mods over 120 watts and able to handle mechanical builds with a resistance as low as 0.12 ohms, these beefy bad boys are what you're definitely going to want to use if you're vaping with extremely high wattage.
Stick With Named Brands
Now that you know what type of vape battery you're going to want to put in your device depending on how you're planning on using it, it's time to focus on brands. It's extremely important to remember that when it comes to batteries, not all brands are equal. If you're looking at buying any battery from a major manufacturer of electronic devices like Samsung, Sony, LG, or Toshiba, you're definitely going to be alright. The same can also be said for major vape companies like iJoy, Aspire, and more. With that said, batteries from LG and Samsung are generally rated the highest out of all manufacturers and you simply cannot go wrong with theseÂ brands.
The Dangers of Using the Wrong Battery
Now that you know what type of battery is good for use in what kind of application, the next step is to learn The Do's and Don'ts of Battery Safety to make sure you follow the information in this post. While using an ultra-high discharge on a low wattage flavour chasing device won't expose you to any dangers more serious than the risk of running out of power when you're away from your charger, there are significant dangers of using a low discharge battery on a high wattage mod. The maximum continuous current battery specification would actually be better referred to as the maximum safe continuous current. While it is absolutely possible to draw more than the rated maximum from a battery, if you're drawing 30 amps of current from a battery rated at 15 amps you're setting yourself at serious danger of the battery venting which could seriously injure or even kill you. Remember that for safe vaping it is always of the utmost importance to your battery's current rating, how much current you're drawing, and never exceed the maximum continuous current of your battery.
