Why Is My Vape Pen Blinking During Use?

One of the most frequent questions we hear is why is my vape pen blinking when everything seemed fine moments earlier. Well unfortunately that’s just the nature of the beast, as many vaporizer issues can appear suddenly, even while the issues leading up to them were gradual.

This can happen when:

  • Battery voltage drops suddenly
  • The cartridge becomes disconnected
  • Safety protections activate
  • The battery overheats

If blinking begins during a session, this is when you should break out this guide and run through all of the various causes. At the end of the day, there’s only so many possible causes for your lights to be flashing and with just a bit of knowledge you’ll be able to easily understand them.

Understanding Common 510 Battery Blinking Causes

Many 510 battery blinking causes involve a communication breakdown between the battery and cartridge, resulting in your vaporizer being unable to get the “okay” signal and start firing up your clouds.

The battery constantly checks for:

  • Proper electrical connection
  • Safe resistance levels
  • Adequate power levels
  • Internal system health

If something doesn't look right, the battery may blink instead of activating. This is done in order to protect you and your friends, as this way your vaporizer won’t just plow through battery issues but instead stop working to prevent further issues from developing.

This means understanding these warnings are essential to maintaining your vape for long term performance and actually getting the full value of the battery you paid for.

Fortunately, most of these issues can be corrected without replacing the battery and are in fact just a normal part of using your vaporizer. While it can be alarming at first, once you have the experience you’ll be able to get things fixed in no time.

Why Does My 510 Battery Keep Blinking?

Now when it comes to the question of why does my 510 battery keep blinking, usually there are several possible answers. The trick here is finding out which one and then making the corresponding fixes.

Most 510 batteries use blinking lights to indicate:

  • Low battery power
  • Charging errors
  • Connection issues
  • Short circuits
  • Safety protections
  • Activation errors
  • Troubleshooting issues

The specific meaning often depends on your specific battery model, but in general when you see flashing lights it means that your vape is trying to tell you something important.

To assist with your sessions, Got Vape lists all of the troubleshooting issues for our 510 batteries right on the product page. For example with the Exxus Vape STAX 510 Variable Voltage Battery we have a run down of its 4 troubleshooting warnings and the corresponding flashing lights.

Thus if you’re having issues with blinking lights, make sure to check online at our site first in order to look for an easy fix. If you still can’t figure things out, run through the check list located below.

Low Battery Power

One of the most common causes of blinking is simply a low battery. As a natural part of using a vaporizer, you’re bound to get low battery warnings during your sessions and shouldn’t worry about these.

Many 510 batteries will flash multiple times in order to indicate it no longer has enough charge to power up your cartridges. As a result it flashes its lights and waves the white flag to let you know it’s time for a recharge.

Common signs include:

  • Flashing after pressing the button
  • Weak vapor production
  • Battery shutting off unexpectedly
  • Short session times

Before trying more complicated fixes, we recommend first fully charging the battery and testing it again in order to see if your flashing lights are just a simple low power warning.

This solves a surprisingly large amount of flashing light issues and is by far one of the easiest first steps you can take in ruling out the issue with your beloved 510 battery. Sometimes the solution reality is this easy, so don’t discount battery issues when dealing with warning lights.

Dirty Connection Points

Another one of the biggest reasons 510 batteries blink unexpectedly is residue buildup that leads to issues with the connection between your vape and your cartridge.

As it takes two to tango with cartridge vaping, when there’s issues with either side of the threaded connection then you can run into some serious issues. As this can interfere with their ability to communicate with each other, you’ll want to fix things quickly.

This is because over time, oil and debris can accumulate around the threaded 510 connection area. When combined with the constant reheating and cooling of your vape, this can quickly snowball into a really sticky situation.

First Inspect:

  • Battery threads
  • Cartridge threads
  • Center contact points

Look over all of the key connection points on your 510 battery and then take some time to clean any that appear to be dirty. This is the quickest way to restore proper functionality and luckily can be done in just a few minutes.

We recommend using a q-tip or swab dampened with isopropyl alcohol in order to scrub away any left over materials. The isopropyl alcohol will make breaking down old stains far easier and let you get back to 100% working order in no time.

Always leave plenty of time for your connections to dry before vaping again and never attempt to clean your 510 battery while it’s still powered on.

Cartridge Not Making Proper Contact

A cartridge may appear fully attached, while still failing to establish a solid connection. This can lead to your battery ceasing to work and your lights to start flashing to alert you of the issues.

Don’t worry, as this is one of the most common 510 battery connection issues we encounter and can be the result of a few different issues.

Potential causes include:

  • Loose threading
  • Overtightened cartridges
  • Slightly recessed contact pins
  • Manufacturing tolerances
  • Damaged cartridge

Now this may seem obvious, but try removing the cartridge and reattaching it carefully. Trust us, you’d be surprised how many connection issues are due to minuscule issues, all fixable with just a quick on and off swap.

While reattaching make sure to gently twist in your cartridge and take your time to ensure that everything is loaded in correctly so that your vaporizer actually fires up and the warning light subsides.

Charging Problems

Sometimes blinking lights can occur while charging and are an indication that something is wrong with your current set up.

Many 510 battery charging problems involve:

  • Damaged charging cables
  • Dirty charging ports
  • Weak power sources
  • Faulty adapters

Got Vape Fix:

  • A different charging cable
  • A different USB port
  • Cleaning the charging contacts

If charging indicators continue blinking abnormally, the charger may be the issue rather than the battery itself. This is where swapping in a new compatible vape battery charger can help you get a fresh start and protect your vaporizer while charging.

Now don’t get this confused with standard charging, as vapes like the Wulf Faze Portable Dry Herb Vaporizer include flashing battery icons to indicate that your vape is actually charging correctly.

Instead we are talking about issues where your vaporizer is flashing and not charging. These situations are when you should use the troubleshooting steps laid out above, as this is when something is actually working incorrectly.

Short Circuit Protection

In order to keep you safe during your sessions, the best vaporizers have a wide variety of systems in place to protect you from dreaded short circuits. As a result if your battery detects one, it often starts to flash and refuses to power up on you.

Potential causes include:

  • Damaged cartridges
  • Internal cartridge failures
  • Excessive residue
  • Connection problems

Removing the cartridge and testing another compatible cartridge can help identify whether the issue originates from the battery or the cartridge.

If your short circuit issues persist even after swapping cartridges, then this could indicate that there is a more serious issue with your battery and you should completely cease to use it until the warnings subside.

It’s always best to air on the side of caution, so if you think your vaporizer is experiencing a short security warning take our advice and do not use it, it’s just not worth the risk.
