Please be sure to inspect your battery before use to ensure it is not damaged including tears/rips in the battery wrap. Discontinue use immediately if battery is damaged.

NOTE: Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled.

    The battery - what can I say? It's a battery, and it works!
    More importantly, I ordered it and my order, as always, was handled and processed in double quick time.
    Thanks again Vapeking.

    Reliable, LONG Lasting, Quality.

    Posted by Matt M on 6th Feb 2016

    In my opinion, there are no other batteries better than these in the 18650 range.. and they come with only a $9.95 price tag!
    They last personally for days in my 200w mod.
    They charge in 2-3 hours with my eFest LUC charger from VapeKing too!

    The colours currently advertised, blue and green, go great with any mods that do show some of the battery, it adds colour and doesn't look out of place at all.

    If you need 18650 batteries, don't go past these!

    Long vapes

    I bought 4 of these for my new Provari 3. So far I had no issues with these Samsung batteries (as opposed to LG HE4 batteries I tried before that occasionally misread percentage left on Provari 3).
    These Samsungs last a little longer than AW 18650 2200mAh. Happy with my purchase!
