Question on 14450 Batteries

[RedAlert]

I know fully charged is 4.18-4.20v, but what is considered dead/low/ in need of recharge? I notice a drop off around 3.78v and was wondering if this is just about dead, or is there a ways to go yet.

Mine quit working when they get to low. I don't know what the voltage level is though because I never checked it.

The trick is measuring the voltage while it is under load. Anything below about 3.4V under load is in need of a charge. There is a fairly sudden drop off for lithium ion batteries, (like about 3 good hits).

If you are a Joye 510 user you are putting a lot of stress (high current demand) on a single 14500 quickly depleting it's capacity. 901, 801,cartomizer and 510 knock-off users need less current. Using two 14500's in parallel or moving to a 18650 will extend the time the voltage remains high.

If unloaded voltage is 4.2 charged and loaded is about 3.6,

Then 3.6 unloaded could be 3.0 loaded.

Obviously not exact values here, but - -

Yup, time for recharge if performance is down.
Why vape if it ain't vaping?
