Genuine Samsung Button Top INR18650-25R 2500 mAh Battery

Attention: We cannot ship batteries outside of the USA. If your order contains batteries, we will refund that portion of your order. 

*New Lower Price*

With a 25 amp max continuous discharge this battery can handle sub-ohm builds down to .15 ohms (at your own risk). 

However, where this battery really shines is when used to power a VV or VW mod.  Our experience so far has been that this battery significantly outlasts the high current drain king of the hill Sony 18650VTC5 when used at the current levels (5 amps and below) that most VV/VW mods are limited to.  Best battery for any VV/VW device, will work in a Provari!!! 

*These measure 66.6mm, about 1.5mm longer than the flat top versions so be aware of this when purchasing! They will NOT fit in the 4nine or Atomo to name a couple. Also, these have a tiny wrapper on the outside that may prevent them from fitting into your device. We do not recommend removing this wrap. This only measures .2mm but it can make a difference.

    Epic Batteries

    Best batteries I've used yet. Stays strong forever. Of course only on the first cycle right now so time will tell the real story.

    Kidney Puncher shipped these on the same day and was impressed with quick they arrived. Great Service!

    Long lasting

    Posted by Nathan in Texas on 13th Aug 2014

    I am using this battery in a SID (10 watts mostly) and from full charge to 3.4 will last me a full 12 hour day. I have two vtc5 (which is mentioned in the product description). Honestly this battery lasts almost as long as the two vtc5s last me.
