My SmokTech and Kalamazoo eGo batteries are getting old so i'm looking for replacements. The Kalamazoo ones are so cool (with the ends that light up), but they also seem to be the least durable and both of those now just turn on randomly and won't shut off, so i don't use them at all anymore. Naturally, i'm also a bit paranoid about safety. Any suggestions for a solid, durable battery i won't have to stick paperclips into all the time (to pull up the center post), that's well-made and hopefully not any more likely to explode than average? Thanks for any brand/supplier suggestions, and sorry if i've managed to overlook any similar recent posts!
