Battery charge times?

[shantyshaker12]

I recently got a new Vamo and a TrustFire TR-001 charger. The new Efest 18650 battery has been charging for nearly 8 hours and I still don't have a green light. Is it normal to take this long? I charged ab Efest 18350 and it took around 2 1/2 hours to charge. This is my first mod other than a Twist, so any help would be appreciated.

It shouldn't take that long. I'd take out the battery and check its voltage with the Vamo.

If it's higher than 4.2 ... your charger was over charging. If it reads under 4.1 ... it could be a bad battery (or maybe the battery wasn't making proper contact with the charging posts).

Shortly after I posted, the 18650 gave me a green light. The Vamo said it was at 4.2 volts so it didn't overcharge. It took about 8 hours to charge. I did try moving, spinning it while it was charging so I don't think it was the contact posts?

Just noticed its maximum charging rate is 500mAh. Still ... 8 hours seems rather long. Not sure what was going on there buy hey! As long as it charged and stopped at 4.2v you are good to go.

Maybe it was the "first charge jitters".

Battery cells need to wake up after being asleep for a long time from the factory. First few charge and use will be erratic, it should normalize after a few uses.

That makes sense, I imagine it was at a complete discharge when I got it although I didn't check it to be sure. It should take less time to charge it in the future then since it won't be at total discharge I would imagine?

I've noticed this happen on several batteries that work fantastic after charging - the ones that I notice it happen to most often are AW IMR 18650s. As always, monitor the batteries as they're charging as a safety measure - if there is excessive heat build up then unplug the charger and dispose of the batteries in a safe manner after they've cooled. The long charge time at first doesn't seem to have had any adverse effect on my vaping. YMMV.

Although I've never really timed how long it takes my 18650 batts to charge in my Xtar charger, it seems to take about 2.5 to 3 hours at a 1 amp rate.
