How to know when to recharge?

[alphahot1]

Hello guys, I just bought my first mod (gp paps + gp spheroid + did atomizer, if you ask me it rocks!!) and can't seems to find an answer to a simple question: I read that is not safe to completely discharge an IMR battery, so how one knows when it's time to recharge with a mechanical mod? I just swap a knew one in when the vapour decreases? Is it safe if I keep vaping until it emits very little vapour?
Thanks for your help!

Ok maybe I was overthinking, the vapor production just drop at some point : )

The vape will eventually fall off, but everyone's threshold is different. It is best to measure voltage a couple times throughout the discharge cycle to see how your taste compares to battery voltage level. Generally, you don't want to drop below 3v but very few people would actually find 3v satisfying. I would assume that most would change batteries at 3.4-3.6v as that is when the vape really starts to go away.
