1st dead battery - (boyfriend's battery) no led light lit up, when you press the button. When you try to charge it the LED light on the charger turns red, then turns green in about 1 - 2 minutes. Try screwing on an atty again, no battery light and won't heat up the atomizer.
2nd battery - (from my set) happen after a few days after the 1st dead one. It wasn't totally dead, it happens from time to time. I would need to constantly clean the battery threaded end with alcohol to keep vaping every few vapes. It's worst with atties. I tried 2 different standard Joye 510 atty on it. Every two vapes I would need to clean the threaded end, or the batteries LED light will be flashing and can't vape. With a carto I can vape for about 10 - 30 minutes then need to be clean inorder to vape again. Sometimes worst, after cleaning, it still don't work. The last time I tried it before getting my replacement it won't work after even cleaning so I gave up. The battery LED light just flashes when you press on it, and it's not low battery. This battery can fully charge though.
3rd battery - (was a replacement I rec'd for the 2nd dead battery) Charged it 8 hours before use. Produce very little vapor, no throat hit, no flavor. It feels like I'm vaping on air or nothing. Luckily this wasn't the battery I received when I first started vaping or it would had completely throw me off, and go to analogs. (Still contacting LF regarding this battery, I just received yesterday)
I hate how my good Riva battery is not working with the eGo-T atty, and that the only Riva battery I can use now. I know the eGo-T atty is ok, because I tried it on my boyfriend Riva battery and they work fine. I purchased a 3 pack eGo-T atty from LF and tried it on my battery, it just won't heat up the atty for some reason. The battery light will lit up but when I vape, no vapor no nothing. It screws on fine. The Riva battery works fine w/ my cartos and regular 510 atties. So sad, I want to go swap my boyfriend's battery.
I think I'm using them properly although I only been vaping about 5 weeks now. Maybe I'm just having bad luck

Thanks Paula, I hope I get better experience when I get another replacement for the battery. It makes me wonder about Riva, and thinking the next purchase for batteries maybe I should try eGo.
