Apologies if this was covered elsewhere, as I did not easily find it.
I am brand new to this hobby, I just received my new ZL SC600w MKIII HI with 3, unprotected NCR18650GA cells.
The research I did lead to me also acquiring an XTAR VP2 charger which the question I have is related to that:
From what I understand, the cells I bought are fully charged once they are at 4.2v, however, the charger indicates that the cell is at 4.2v, but the LED never changes from red to green, is this normal?
Is this possibly due to the cell not having protective circuitry to create an open circuit for the charger?
I let the cells sit in the charger for awhile (30m or so) while they were indicating 4.2v, and then pulled them and tested them with my DMM (Fluke 87) and both cells are measuring exactly 4.2v.
Is there something I'm missing here?
After your reply I decided I was willing to potentially "sacrifice" one of my cells to see if it ever turned green and, it did.
I'd be interested in knowing what takes it so long to terminate once it's at its rated voltage, it took nearly an hour.
My website with battery and charger information: lygte-info.
More than 1000 reviews of batteries, charges and other stuff.
Compare 18650 LiIon batteries or smaller (RCR123, 16340, 14500, 10450) LiIon batteries.
Thanks for the information guys!
Hopefully my ignorance helps someone else.
My VP2 no longer charges. Warranty expired last month.
What seems to be the issue?
Wow. My VP1 is still charging strong.
Mine are still holding up, but I also bought a 3rd backup for some insanely cheap price on sale because it looks to me like they may stop making this model with the SV2 and all their VC models out now, and the new VP4 Plus. A pity I don't like their new look they have been rolling out across the line. I'm happy so far with how the SV2 works though, have it charging 2 26650 batteries at 2A each right now. I need to get a lot more runtime on it though for 18650 the VP2 is still my go to or my WP2H. For analyzing though the lineup of course is different; I don't really need more chargers, but better analyzers. I may just get another electronic load as the price of the top chargers move up.
Two things: Might depend on the version you have...1st Gen (sold for $50 when launched and quickly dropped to $35) was recalled due to enclosures separating in temp extremes, and if you didn't recv' adequate notice of recall you may be able to exchange for a functional unit or get your's repaired gratis.
Sometimes depends on where purchased e.g. if from a distributor, like illuminationgear for example, he might be willing to go to bat for you if just out of warranty...pays to ask.
After an overnight rest with the power supply disconnected from the charger, the VP2 is functioning correctly again. Hmmmmm, weird. Charged a 26650 at 1A and a 16340 at 0.25A

The VP2 is my favorite and most used charger...a true workhorse.
Cool. Good to hear that it is "working" again.

I have an Xtar VP2 that I just smoked(literally, smoke came out of it). Can anyone recommend a new 4 slot charger?
Is the power supply 110-220V?
Fyi, as an answer to my own question, I've been informed by a vendor that the power supply is 100-240V.
