18350 charging capacity?

[k av]

I ordered a vamo kit that came with 4 18350 batteries that say 3.7 volts. I charged them only until they were finished charging and when i check the battery voltage on my vamo it says 4.2. Is this overcharging or is the battery possibly mislabeled? I tryed to look around for other information and some people say 4,2 and some say 3.7

Thanks

They charge up to 4.2 volts and the nominal voltage is 3.7 volts. You are safe to go. If it charges above 4.2v then it is considered overcharged. BTW what charger do you have (any labels)?

Thanks very much, no label or branding on the charger Only says Model: HD-3013 on the back. I plan to grab a nicer charger soon just for safety, but this one seems ok.
