This battery I bought as a spare battery for my 70D, so that I can keep shooting if the standard battery is the way completely sucked. And now I just use my batteries alternately. Although the capacity of this battery is smaller than the original (1300 to 1800) can rely on the part of the useful life of the standard mode is not much shorter. When my values are currently at about 1.5-2 days with about 300 photos per day (active on holiday tested).
Whether the battery is durable, I can not yet assess currently, because I use it only for about 4 3 weeks.
