When to change coils?

[doctorjellybean]

How does one know it is time to change the coils? I'm using a Kanger E-vod, and have a 5 pcs pack Clear Cartomizer Coil Unit. When changing, can one re-use them?

Oh, does juice go off? I'm still using the 50ml bottle I purchased at the end of January. Admittedly I didn't start full scale vaping till err March ... had to finish my tobacco first

Change it when it starts tasting bad/burnt or the amount of vapour decreases even with a full battery. Juice should last at least a year.

Yes you can re use the heads. Most of us soak the heads in denture tablets, non mint flavour over night. Give them a really good rinse off and leave to dry and should be almost as good as new.
Other option is to just wash them out and dry burn them or you could re coil them yourself.

Im sure the shelf life of most liquid is 2 years.

You change the coils when you need to, depends on the juice you use, the atty and your own taste.
Anything from a day upwards, I've tried coils that have been fine for a month, then the same one has lost taste in a few hours. Different juices.

I'm using juice that is 2 years old with no ill effects.
