No, they are usually lower capacity at best, but at the worst, they could damage your camera. Just thing "Samsung S7"
That being said, when I bought my D800 from B and H in 2013 (?), they threw in a Pearstone battery. It works, but it only has about 75% of the capacity of the Nikon OEM.
Samsung S7 not really the same (to mimic the commercial). The Samsung battery issue was with OEM battery which would be the same as your Nikon or Canon with OEM batteries catching on fire.
