D500 owners - battery question

[Simpo Two]

I'll need more than one battery and am in the genuine vs generic dilemma...

I like this twin charger with two generic batteries (2100mAh as opposed to 1900 of the genuine):

My questions are:

Are there any known issues with generic batteries in D500s?

Will the charger charge up the genuine battery? (the seller doesn't accept questions)


If there are likely to be problems then I'll get genuine ones, but I do like the twin charger.

Thanks

I found the same product on Amazon for less so thought it was worth a punt. We shall see!

I've got one of these chargers (and batteries) and it charges up both generic and genuine batteries fine.

That's nice, but too late now!

(1900 or 2100 mAh?
