Hi everyone, I've had my Aspire Sub Ohm for a couple of months now, and I'm not a heavy vaper but it has always treated me well and never had any problems. I recently tried to charge it after the battery had died, and everything looks normal on the charger, red light on the USB and an orange light around the fire button. I left it in overnight, turned it on the next day and it gave me one half-hearted hit and died. Tried charging it with different outlets and USB adapters in case I had mixed them up, but everything gave me the same result. I then brought the battery to the shop I bought it at, and they basically told me that the battery just gives out after a little while and I'm pretty much SOL, and then they tried to convince me to buy a new one.
Is there any troubleshooting I should do or should I start shopping for a new vape?
I've had it since February and it has never had any trouble before, two days before this happened it was charging just fine. I use the Atlantis tank on it and that still works perfectly, no complaints there.
