So I got screwed by GreenNicotine (basically these dudes that take stuff from GreenCig and repackage it and sell it for outrageous prices to new unsuspecting new vapers at mall koisks) and found out here their batteries work with Vapor4Life Cartomizers. well, my battery is starting to crap out on me (surprise surprise) and I just ordered a V4L battery. my question is, will I need to buy a new charger for my V4L battery as well, or can I just use my GreenNicotine charger? Somebody said that they could be wrong but they thought GreenNicotine reverses the polarity on their batteries, so I gotta get a new charger. is this true or can I just charge the battery on the charger I got now?
