Ok so i cant post this anywhere but here since i ma new member but i was hoping i could have a few questions answered for me that i have searched and not come up with. So when i first got my svd i got 1 efest 18650 2000mah battery with it and a trustfire charger(grey one with 2 slots) all was happy and well. That was about 4 or so months ago. lately (last 3 weeks) ive been using my svd very regularly as ive found juices i like and also learned how to properly use my svd vw mode (love it) and ive started to notice my svd never shows a green charge anymore for my battery. Is this to be expected because ive had this battery for so long? i used to put that battery on the charger when it would go red on my fire button, and let it charge. Now after its been fully charged everytime i use it my fire button is yellow displaying a medium charge for only a few puffs and then goes red, ive just been using it as it hasnt yet completely died on me and then charging it later at my convenience. It displays usually around 3.6 or 3.5 volts after a full charge, what should it really be after a full charge, and is my battery dieing on me? Or is it my charger?
