They don't need an 8 hour charge from what I can see because they don't develop a memory.
The 510 I bought worked great with the initial charge that came with them. I get throat hit because I use menthol. I'm not really one to judge different juices yet because I haven't tried too many different kinds. I also use 36 nic content though (with VG mixed most of the time).
Now, one of my batteries won't work with the atomizer I've been using. I thought it was dead, but it works great on the other atomizer. Sometimes these things are just screwy!
