I bought this battery from a third party Amazon seller at a reasonable price, it has unfortunately proved to be a forgery! A beautiful infringement, with a copy of the Canon hologram. However, if you check on the Canon Web site, you will find that this hologram on the packaging does not match what is described! So be very careful, and take time to check ...
I then bought the same battery but sold directly by Amazon for a few euros more. This time it was indeed genuine battery, and I could see the differences (true hologram, sealed packaging, no typo).
