Due to the Samsung 25R Battery having a worldwide 
shortage. We are now selling the EFEST 25EF which 
is intended to be a battery with similar performance 
and capacity.This 18650 battery is used for most 
vape devices and is one of our most recommended 
battery for the longest-lasting performance and 
value for money.This battery has slightly less 
capacity than the 30EF, but the price is also lower.
