Batteries in e-cigarettes can be a great mystery, but they don’t need to be. Here’s how you can figure out the lifespan of your e-cigarette or vaporizer.
You’ve probably come across several confusing phrases when you’ve been shopping around for e-cigarettes and accessories – and one of them is “mAh”. Typically, this measurement is used to explain how much battery power each model has, and higher numbers are associated with stronger batteries. But what exactly does it mean, and why does it affect you?
Our guide will answer these questions and much more.
What is mAh?
Well, mAh stands for milliampere hour, and it illustrates a battery’s total charge capacity. It usually measures how much energy can be stored in a battery at any given time. For example, if you had a 1,000 mAh battery, it would be able to consistently deliver one amp of power for 60 minutes before it was completely out of power.
Because of this, batteries with higher levels of mAh would be able to support power-hungry devices for longer periods of time before it needs recharging.
Unfortunately, there is a trade off to consider here: greater levels of mAh generally translate into bigger batteries which are heavier to carry around.
Why mAh matters for e-cigarettes
Learning about mAh will help you determine the lifespan of your battery, as well as the number of puffs you’ll get out of a single charge before it’s completely drained. Before this though, you need to figure out how much electrical current is being used by your cartomizer and battery.
This can be a little complicated if you’re new to vaping. First, divide your battery’s voltage by your cartomizer or atomizer’s resistance level. For example, according to Vapegrl.com, a 3.7V battery coupled with a 2.5 ohm atomizer will draw 1.48 amps (that’s the equivalent of 1480 mAh). Don’t worry if your components have different levels of resistance or voltage – just use the Ohm’s Law Calculator to establish how many amps is drawn by your e-cigarette and times it by 1,000 to learn the mAh.
Calculating the battery life
To figure out how long your e-cigarette will last before the battery needs recharging, it’s worth having a gander at the Battery Life Calculator. Here, you can type in your battery’s mAh into the first box – and then, in the second box, type in the number you generated during our last step. This normally results in a decimal number. By multiplying this by 3,600 – which is how many seconds are in an hour – you can establish the exact number of seconds that a battery is going to last on a full charge. For example, 0.221 hours multiplied by 3,600 equals 795 seconds.
Predicting the number of puffs on a full charge
Now you’re a mAh-ster, it’s time to work out how many puffs you’ll be able to enjoy using your e-cigarette before it runs out of power. Take the battery life you’ve just calculated and divide it by the average amount of time you spend taking a single puff on your device. If your typical drag lasts for about three seconds, dividing this by 795 would mean that you’re going to get roughly 265 puffs on a single charge.
Unfortunately, this is only ever going to be a ball park figure because resistance levels can fluctuate when you are using your e-cigarette, but at least you’ll have a rough approximation of when your battery is going to need recharging.
