Vape cartridges and batteries can both fail. Sometimes it’s just a bad point of contact and nothing is really broken. Here we go through the first thing to do when your battery is flashing on your vape cartridge and it seems to be broken.

This applies to threaded batteries that are not using a magnetic adapter. Here we specifically used the Vessel battery in our demonstration video below.

This same technique works on other batteries as well. A cart can be dead and a battery can fail, but try this before you start trying to figure out if something is broken. Another common fix on mod and wax pen batteries is adjusting the center pin.


  1. I’ve done all the troubleshooting such as raising the center plate, loosening the cartridge, cleaned both the battery and cartridge threads, and the light turns on and doesn’t flash but it’s not heating up but it’s not the cartridge I’ve tested it on a different battery but I can’t seem to figure out the problem. It’s fully charged and I’ve gotten rid of the flashing light but now it won’t heat up, what should I do?

  2. My battery flashes white when it isn’t charged but I charged it and it flashes red then it stays on but then it turns off. At first I thought it was the connection and I lifted the center plate because the last time it wouldn’t heat up or charge and it fixed but I screwed it back on and it still won’t heat up or charge and it keeps blinking white when inhale.

  3. Just bought pen today has worked perfectly all day now it’s blinking blue fast blinks not sure what’s going on it is completely charged

  4. I thought my battery just stopped working and I was going to have buy a whole new one but then I found this and watched the video. No joke the very first “hack” to troubleshoot it worked. I am so excited. Thank you!

  5. My vape just has a white light when it’s plugged into the wall when I take it out and put it together it doesn’t turn on flash nothing,please help!

  6. My battery doesn’t have a charger? And I’ve never really put much thought into that but now it is blinking? Is it broken or what I’m just confused?

  7. i have a cart, and it’s been working just fine until today. this morning i realized when i hit it, the light doesn’t stay on as long as it normally does. then my battery died so i charged it for a bit and put my cart in but when i held the button it started blinking, when i took the cart out and pressed the button the battery was working fine. the small piece on the bottom of the cart came out but i found it and put it back, i thought that could have something to do with it but it’s in exactly how it was before. do you know how i could fix this?

  8. My lookah flashes orange like ten times whenever I put a dab cart into it but when I switch it back for the regular quartz tip it works just fine I’ve cleaned it I’ve loosened and tightened I’ve turned on and off I’ve tried almost everything that makes sense some help please I love the hit with a cart on and attached to a bong it’s soooooo smmooootttthhhhh!!

  9. So my battery charges and it can stay on the charger for an hour and it’s still red when I take it off the charges it flashes red a couple times but then it won’t turn on for me to use it. Can someone help me

  10. My light won’t stop blinking when I hold the button down. I put in a cartridge that I’ve used before and it just started blinking after charging it through the night. What could it be. I’ve already tried troubleshoot
