I purchased a pair of trustfire 14650 batteries for my ePower because I apparently vape wayyyy too much and wore out the set that came with it. These new batteries are 1300mAh, but otherwise identical to the originals. When I received the new batteries I immediately threw one on the charger that came with my ePower. Well here I am 4 hours later and it's still showing a red LED (charging). Does this charger not work with Trustfire chemistry?
