Ask a Question
  • You say the Firefly replacement battery you sell is 770 mAh (which is the new, improved kind), but down below you say that it is the "original" replacement battery. Which is it, for sure please. (I have had the original ones, and they're crap and poop out almost instantaneously, whereas the 770 are supposed to be better.

    Hello Lyn. This is the 770mAH firefly 2 and 1 repalcement battery. What we meant by "original" is its an authentic battery from manufacturer.

Should have ordered a long time ago

The only thing more useless than a dead battery is a brain refusing to acknowledge it won't come back to life, and having TWO dead batteries. I saw the light, both figuratively and literally.

It's a battery..., seems like.., a battery! Works like one, too.

It works to power up my FF2+, does what's expected. Havn't had it long enough to comment on it's longevity etc. That to me is the main concern, it's "long life" or not. We'll see. Aside from that, your service has been great. Thanks and have a good day. Guy.

Saved my vape

No one else in this hemisphere had these batteries in stock, and I wasn't about to pay $60 just in shipping to get one from overseas... I was about to give up, but then I found Not only in stock, but great price too, so I bought two!

Finally found it!

I could not find this battery anywhere. They have been sold out on the Firefly website for over a month. Finally found it at Slick Vapes and it was delivered quickly. Feeling much better now.
