I just received my new 510 manual batteries I put the first one on charge and it went to full charge no problem. I put the 2nd one to charge and in about 5 -10 minutes the darn thing blows up. 
WTF it smoked up my office really bad. The battery was shooting sparks and blowing a lot of smoke. I pull the USB charger out of my computer and douse the battery in water.
Has any one else ever had this problem with any e cig batteries before I need to know.
