I hear ya. I wound up with a PCC the size of a paperback that would charge four batts at a time.I don't know how anybody got more than 30 minutes out of the 180mAh 510 batteries. I remember reading an hour to an hour and a half, but I was amazed if I ever had one last longer than 20 minutes. Then it took 1.5 hours to recharge. Had to carry 9 batteries and a PCC that plugged into my computer to get close to lasting a workday.
I'm very thankful those days are way behind me. I'll never take a 2000mAh IMR 18650 for granted. Those things have saved me so much grief...
