Thanks all, I was thinking more of the capacity than the ruggedness. But yes, a genuine Canon one looks like what I will go for.
Makes sense, the only caveat I would give you is that marketed capacity of a battery isn't a great indicator of how well it will work over another lower capacity battery. How they discharge over time is more important, one battery that is lower capacity could be more efficient during discharge, outlasting one that is higher capacity but not as efficient. There are different resistances and different cut-off thresholds depending on the manufacturer of a battery. Another factor might be that a 3rd party higher capacity battery may last longer than a factory battery, but may degrade faster over time, and become much less usable, making you replace it more often than the factory.
You just have to juggle cost vs gain on these things, and is why many say to use tried and true 3rd party batteries like Wasabi and Sterlingtek, because they have the longest track record in the 3rd party space.
