Full Description

The Samsung INR 18650 25R is an excellent battery cell for vaping. Its strength is to be both a high drain battery as well as a large capacity battery cell. Battery cells are, either, great at delivering a high Amps discharge in bursts or at delivering a large capacity over a long period of time - but not both. The Samsung INR 18650 25R is good at both and delivers a perfect balance of power and capacity that is ideal for most vapers. These batteries are powerful - if you do not understand how to properly handle batteries - do not buy them.

VapeShop comment:

These cells are the real Samsung 25R battery and therefore come with a sticker required to clear custom. You are welcome to remove the sticker on reception if you wish.

Works Great
The battery itself has a great life span. I've had my old one for over 3 years and it is still going strong. For the price, you can't beat it.

back up
My battery is only 3 months old but I'm realizing how important back equipment is in the vape world. I would rather buy one here at a great price then shop around town when I need one and pay a higher price. Peace of mind.

works as it should, real deal.
Couple dollars more than some places, but came in an actual Samsung box w/o sticker over the print on the wrapper. Running my pico like a charm.
