Does anyone familiar with this charger know if it is good at telling me if my 18650's should be retired or not. I have one on the way from China and wanted to use it to check some year old hg2's I have and was wondering if the capacity check feature is useful at telling me if my batteries are shot or not. Also would it be good at telling me what batteries are similar in usage that I can marry. I'm already married 2x2 batteries that I used to use in a single mod for about 9 months but I'm hoping this charger will tell me if they are close in capabilities. So my question is did I get the right charger for my needs? Mooch I'm looking at you
