4 nine mod battery

[cloudyjosh]

hey guys recently got a 4 nine mod using sony vtc4 "flat top" works great! Today I got purple efest "flat top" and can not get It working even tried ajusting rda pin anybody know why? They work in my old AR mod fine but when in the 4 nine the button just doesn't feel like it pressing properly!

Are the two batteries of identical dimensions, including +/- end plate to outer sleeve? If not, there's your probable issue.
