I drip and when I started I could get attys that were lasting me almost 2 months, now I am getting attys that might last 2 weeks, if lucky. This is getting expensive. I pay $5 to $10 bucks and get the same quality as if I pay 35.00 for a bulk order of 10, they all are going fast. What am I doing wrong? I use the extra long V4Life DSE 901 batteries. Got any suggestions?
