When i got my vape everything worked just fine and i was very pleased with it. My first battery was an offbrand that worked until it died. I then read that i should get a samsung 25r. I got two of them and one worked until it died too. Then the other batteryworked till it died. Every battery charged before they died. Once theyre dead they dont charge or do anything. I usemy vape to charge them and i dont want to but an external charge because it may not work. Please respond ASAP it would really help because i dont have anything to vape now.
