Hi
Well there is no harm in checking each cell. In a totally flat state they are safe, I've successfully recharged 18650 cells that were at 2.8 volts but I'd never consider any lower than that no matter what you read on the internet. I did a course run by Sony in 1995 on lithium ion batteries and the dangers were well documented back then and what I was taught sticks. All I can say is meddle with these batteries at your own risk, never never fire amps of charge current into a severely depleted Li-on to kick it into life, £100 is a lot cheaper than loosing your sight etc
