Ordering two EH 18650s tomorrow. I will report back to this thread after a week of using them almost exclusively if I can remember to, since this thread already has a good google ranking when searching "ecig EH battery" Hopefully they work well. You can get 2 2000mah EH 18650 batteries for $12 in comparison to the $20 you would spend on the same mah AW branded batteries.
I have had a bad experience with ONE of the EH batteries I have. I had a red button top, & a blue flat top 18350 EH batteries, and the red flat top just stopped charging. I don't believe it was from over-discharge, but it could of been & my memory has pushed that fact out. The BLUE flat top EH battery still works flawlessly & it actually does just as well as any AW 18350 battery. I also have two 18500 EH RED batteries that work fantastically, with no complaints from me. They seem to be on par with any AW battery vape-quality wise. & they have lasted me over a year with minimal use.
I'll report back here after I've used the 18650 EH RED batteries for a week or so.
