Hello everyone. I just bought a new to me Provari and ordered two AW IMR 16490's along with the Tenergy charger from ProVape. The first time I charged the batteries one lasted me about 10 hours. Since then the charge times have been decreasing and the battery life has been decreasing also. The first full charge took about two and a half hours. The next charge about 2 hours. And yesterday about an hour and a half. This morning I started vaping at 7 a.m. and by 10 a.m. I had gone through about 2 mL of liquid and my battery which started at 4.1 was down to 3.2 and needed to be charged. This seems bizarre and not right. Can anyone weigh in on what might be going on? Thanks in advance.
