Lasts all day plus if your not constantly vaping, if you are someone that is hitting hard all the time you may want a spare to swap out, I bought two of them so I always have one fully charged and I swap them out every other day. I'm thinking about ordering two more just because I want to have them on hand ready to go.
Good quality battery

Bought a SMY50 mod box recently, and tried several different batteries. This battery is by far the best. Last even longer than my 2500mah Samsung batt, and holds full charge much longer.
Long lasting battery!

It's perfect for my Lavatube, goes strong all day and then some! Two thumbs up!
