Getting an Original SAMSUNG INR21700-40T 4000mAh (9c) LI-ION BATTERY is almost impossible, As Samsung Officially does not sell any original batteries.

There are a lot of people selling FAKE cells in the name of SAMSUNGThat too at very high pricing.

So we have imported and tested samples from 4-5 sellers and this one is the best among them with good quality & performance for a reasonable price!!!!

As we do not want to cheat our customers, We are marking them as a copy of the product name itself.

Note: we do not recommend this battery for most e-cigarette applications, the protection limits the cell to ~15W.

Note : Color may be different in actual product .
