I have 2 batts that a only a month old. I normally use the wall adapter to charge them but have noticed they seem need re-charging more frequently then when I first got them. If I am in the house I usually have a batt on the charger most of the time. Before I go to bed I take the last batt used & put in on the charger. I then put the batt I just charged into the PCC overnight. In the morning the batt in the PCC (freshly charged & not used) typically has about an hour of use before it needs re-charging. I've also noticed batts charged in the PCC seem to have a shorter life then those charged on the wall adapter. I do not consider myself a heavy vaper. Hopefully I should not need new batt already. Currently I am having to charge each battery an average of twice a day. Is this normal?
