But be careful:
To me it has happened before that a Nigel Nail New Original Canon LP-E6 battery already malfunction of the charger to the first charge was displayed.
The reason: The batteries are delivered probably not 100% charged. So if the battery is already a long time on the shelf, it is possible that this is "deep-discharge" and one with the original Canon charger has no chance to charge them. Remedy can be procured with chargers that can do this. Or just simply - If the battery has only purchased new - this again Information Exchange.
Although this is an annoying affair which does not have to be, but does not change the performance of the battery.
Nevertheless, I say: rather buy an original. (Even if he arrives :-) Alone empty already case of complaints, should sometimes leak and damage the body of the battery.
