How to Know When to Replace Your Vape Battery

There's no bummer like a dead vape pen battery. One day it's firing on all cylinders, and the next, it's like it's barely hanging on. Most of the time, a nice long charge is all it needs to get things back up and running. But if you're constantly struggling to get your vape pen battery to hold a charge, there may be no saving it.

So how do you know it's time to replace your vape pen battery? Let's dive in.

How To Know when to replace your vape battery

Not sure if your vape battery needs to be replaced? Here are some telltale signs that indicate it may be time for a replacement.

It's too warm

You may notice that your vape pen battery feels warm to the touch after using it for a while. This is perfectly normal (especially if you've been vaping in a hot climate). But this could also be a sign that the battery is working too hard and needs to be replaced. If it constantly feels warm to the touch, it's time for a new one.

It's rusted

Over time, your battery will likely develop a small rust spot or two from either chemical leakage or corrosion exposure. While it's a normal progression for all electronic devices, ignored rust could damage your vape. Better to be safe than sorry and replace the battery if you see any rust developing.

It's leaking

Not to totally freak you out, but leaky batteries are seriously dangerous. Any kind of leakage can cause your battery to overheat and explode. You've seen the terrifying news stories of vape explosions and the damage they can cause. Don't risk it—if your battery is leaking, get a new one right away. Batteries can be replaced, but you can't put a price on your safety.

It's damaged

If your vape pen has been dropped or knocked around, it could cause serious damage to the battery. After a bad drop, it's always a good idea to pop open the pen and check on the battery. If it's physically damaged in any way—we're taking dents, cracks, and deep scrapes—replace it as soon as possible. Ignoring damaged batteries can lead to big problems down the road.

It takes forever to charge

Batteries don't last forever, and over time they'll start to lose their ability to hold a charge. If you put your vape pen battery on the charger and hours go by without it reaching full power, it's time for a new one. Vape pens should take only an hour or so to charge, so if yours is taking significantly longer, the battery is on its way out.

You're getting less drag per charge

When you first get your vape pen, it's powerful and full of juice. You can take hit after hit without any issues. But as the battery wears down, you'll notice that each drag is weaker than the last. The time between having to charge the battery also starts to shorten. If you're constantly wondering why your vape pen just doesn't hit the way it used to, it's time for a battery replacement.

You're constantly getting a low-battery alert

Most devices on the market today come with a digital indicator that tells you when the battery is running low. Whether it's a red light or a picture of a battery with a line through it, the message is clear: time to recharge. Getting that message every so often is normal, but if you're seeing it more and more frequently, it's a sign that the battery is on its last legs.


How long do vaping batteries last?

Like all technology tools, vape pen batteries have a shelf life—and it's not always a long one. Most of the models you'll find on the market will last you between four to six months. However, the battery on a high-quality device can last well over a year, depending on how much you take care of it. 


No matter how well you take care of your vape pen battery, it will eventually reach the end of its usefulness. However, there are a few things that could speed up its expiration date, such as:

  • Improper storage: Batteries should always be stored in a cool, dry place away from direct sunlight. If they're exposed to extreme temperatures or excessive moisture, they could be damaged beyond repair.
  • Using a bad charger: Cheap chargers are all over the place, but using one could compromise your battery. Always use the charger that came with your vape pen, and don't try to charge it with anything else.
  • Misuse: Accidents happen, but if you're constantly dropping or misusing your vape pen, it could cause serious damage to the battery.

To Sum It Up

Your vape pen battery is like the engine of your device—it's what makes it go. And just like any other engine, it will eventually run out of gas.  Knowing the signs that indicate it's time for a replacement can help you avoid any nasty surprises (like a dead battery in the middle of your session).

Keep an eye out for rust, leaks, shortened charge time, and a weaker drag. If you notice any of these things, it's time to head to your local vape shop for a new battery.

FAQs

How often do you change your vape battery?

It depends on the kind of vape you have and how often you use it.  For most people, changing the battery every four to six months is sufficient—but some models can last over a year.

How do you know when a vape is dying?

There are a couple of signs that indicate a vape pen battery needs to be replaced. If it's constantly warm to the touch, has developed rust spots, is leaking, or isn't hitting as hard as it used to, it's time for a new one.

How to tell if your vape battery is bad?

The best way to tell if your vape battery is bad is to take note of how it's performing. If it's not holding a charge as long as it used to, if the hits are weaker, or if it's leaking, those are all indicators that it needs to be replaced.
