Good replacement battery for Canon 100D hold, as long as the original Canon battery. According to imprint the capacity is even 25% higher. A star deduction there because of the state of charge of the battery of the Canon is not 100% accurate display, or in other words, the camera displays all the time four beams on, then switch 3 bar and suddenly get the message to the battery. This is the original not so when it can do but live with it.
Supplement: I have two more must deduct star because is already broken after approximately 20 charging cycles of the battery. Considering how much hazardous waste If you produce these replicas, I can only advise everyone to the expensive original Canon to buy.
