I would say take a visit to the Vape Shop and bring the batteries with the charger. They will be able to tell you what is going, and probably at the same time put the batteries on a charger so you can at least go home with a working mod. AND you can figure out how to better charge them yourself, whether it just takes a long time or you need to get something new!
For sure it will be worth the visit. The sooner you go, the sooner you Vape!
