My cartridge isn’t connecting with my battery!

This could be for a couple of reasons, let’s walk through them below. 

The connection between the battery and cartridge could be dirty. Maybe some sticky oil leaked out over time and got inside the battery threading where it connects with the cartridge. It’s common for dirt and grime to build up here and interfere with the connection between the cartridge and battery. 

Before you recharge your battery, get a Q-tip or cotton swab and some rubbing alcohol. Gently wet the cotton and swab around the area where the battery connects to the tank or cartomizer. This should break down most of the buildup in that area. Check the air holes, and swab over those as well if you can see any visible buildup.Before you plug the battery in to charge, make sure you have wiped it completely dry.

When the connection is dirty, it becomes difficult for power to flow with ease, making the device function poorly.

The other reason the cartridge might not be connecting is because the connecting plate at the base of the cartridge got pressed in too far and it no longer makes contact with the battery. 

When this happens, it’s a super easy fix that requires just a paperclip or a small knife. On the base of the cartridge, you can see a rubber gasket at the bottom with a small metal piece in the middle. All you need to do is pull the rubber and metal pieces out just a little bit. Be careful not to pull them all the way out, you’re just trying to reposition this part to be flush with the bottom in case it got pushed too far in.
