I blew out my smok by using a 2 amp charger. So I had to toss the batts and mod. Just picked up a g-priv and I put in 2 efest batts that where drained way to empty. Now I am charging my new mod and every time I take a hit it drops from 24% to 20% and so on power wise. Is this only happening because they were drained and sat for 6 months? New batts needed? or will they charge fine? Or who the hell knows. I'll find out in a few hours anyway. I know nothing about batteries so any education would be appreciated.
