My 5 XLs work fine, but I do notice that if I
vape the batts dry, the charging process is a bit weird. The batts don't blink, and the charging lights turn red, then right back to green. When I check everything a while later, the lights have gone back to red and stay that way until the batts are fully charged. Either way, they do charge fully.
I hope your situation works out. I just ordered two chromes myself this weekend to seek an Olympic medal. Go Team Jeffree!
