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.
