Are these any good. I ordered a pair off the site I used to order my vape batteries on before I quit. They usually don't sell had quality batteries, but I wanted to make sure these are okay. I got them pretty cheap.
My apologies if this is in the wrong section.

I've always had good luck with Efest batteries. As long as they're genuine, and they probably are, you'll be good.
Which site did you buy from?

Thanks. I got them from RTDvapor.com and every orhernbattery I had bought from them has been genuine. This pair has an anti-counterfiet QR code on it.

I've bought from RTDvapor before, and have had good luck with them. :)
Yeah. I have always had great luck with em'.
Edit: you can use the single charger that comes with the 18650s that often are with the 301s, 303s, etc. Right? I have the charger that is made for these, but I wanna be sure for just in case it breaks.

I don't know if thithis is relevant or not, but this at least shows some averages, maybe.Efest 16340 850mAh (Black)-info.png
 
Huh? If I'm reading that correctly is shows measured capacity to be 586 mAh at best and 278 mAh at worst. That would be disappointing to me if I measured it that low after expecting 850 mAhs.

Eh. They were $3.99 a piece. I wasn't expecting much from them.
Mine may measure slightly different, I just don't have a meter of sorts.
