to answer all these replies....
i have 3 chargers that have gotten steady use since April. All 3 are screwy with the indicator lights. I usually let a battery sit in a charger for 4 hours--or overnight if I am getting for bed.
At work I vape almost constantly, no joke. I'm surrounded by smokers and pure job stress. I do go between just biting down on 901 and actual vaping but I do vape a LOT. I only set it down with my teeth and jaw get sore.
This is second set of batts I've bought from this store--last set lasted about 2 hours also, I'm thinking. I may try another store & get a couple chargers while I'm at it....
btw, what does it mean when a battery flashes like 50 times in a row (not the normal I'm dying flash of two times)
