VAMO Battery Charging Question

[wv2win]

I haven't had to charge loose batteries in a couple of years, so I'm rusty. I just charged the 18350's on my Trustfire TR-001 charger for the first time. They were on there for about 5 hours and the lights have turned green indicating fully charged.

Is it OK to start using them?

Thanks

I don't see why not? Just check the battery on the vamo/multimeter(i think? thingy that checks batteries) to make sure it's not over-charging would be my only advice there. If I'm wrong, someone let me know. When my batts turn green, I use em. Check em, then use them.

If the lights are green, you're good to go. vape on!

Thanks, guys.

My advice (for what it's worth) is to get a multimeter, usually 10 bucks or so. This way you will know true voltage at charge and discharge. You will be able to monitor the batteries condition much better this way and know if you have a bad one so you can get rid of it as it could be a danger to you, especially if these are old batteries you're using.

I have one, just didn't want to go pull it out of the garage. And these are new Efest's.

New efests, good choice, should be fine. Still might want to get your multimeter out for piece of mind.

One other item, when finished charging, let the batt cool for a while. I had read 3 different post's that mentioned it. I have no problem because I have 4 in rotation.

This is not needed, and the original source of this recommendation is completely arbitrary.

The Li-Ion charging profile slowly tapers off the charge current after the battery reaches 4.2v; the Constant Voltage (CV) or saturation portion of the charging process. The the cutoff current (the point at which the light turns from red to green) is typically less than a 1/10th of the full current; ie: a 500mA charger will typically have a cutoff current less than 50mA. Because of this, the battery has already "cooled" and there is no stress to alleviate by letting them rest.

Well yes this is a very good idea, actually your batteries should not even be warm to the touch after charge if you are using a quality charger like the nitecore for example. If they are getting warm when charging you should not leave unattended or better yet trash the charger and buy a different charger.
