Efest batteries experience?

[tankie3k]

I was at a local electronics store and found some 4000mah 18650 cells, for 15 bucks I picked them up but I have no way of testing them right now. Does anyone know if Efest is a reliable company? I know vapcell makes 4000mah batteries but they're the only ones I've seen. There seems to be very little reviews of these around.

Efest's official website does not list a 4000mAh 18650 cell and I can only find a couple of mentions of 4000mAh cells on vendor sites, so I'm going to go with probably fake.

Genuine Efest cells have an authenticity sticker on them with a scratch off panel revealing a unique ID string. Do yours have that sticker? If they don't, you've been scammed

They did, I also found the same model on 18650 battery store

In that case they might indeed be legitimate. Only way to find out is to charge and use them
