18650 UltraFire Lithium-Ion Rechargeable Battery, July 14, 2017
Reviewer: Frank J. from Burnsville, MN United States  
This battery is not the standard size as it has a positive post that protrudes approximately 3mm longer than the standard size which makes it useless in any vaping hardware or in any item that does not have a compression spring in the battery holder to accommodate the additional length. Useless to me. I also can't comment on its' performance as I don't own anything that has a compression spring in the battery holder. This should have been in the description of the item.

Reviewer: Ronald Harmon from Monroe, MI United States  
Maybe it was just me, I usually use Sony 18650 2100Mah
Batteries and thought these 4000 MaH batteries would last longer, but they actually last less than my Sony batteries.  So I'll stick to the Sony batteries.
