Yeah, there isn't much we can do with the information you have provided other than to recommend buying some authentic batteries from a reputable supplier. Honestly, and I'm sorry about your earlier purchase, but don't vape them they may be severely underpowered, you don't know their specs, it's just not a safe idea.
If it's any consolation, buying from reputable vendors is often and usually cheaper than buying elsewhere, and batteries are the one thing it's not safe to skimp on, when it comes to overall vaping safety. Toss them (well, recycle them) and get some safe batteries.
