MB-D17 and a EN-EL 18a Battery

MB-D17 and a EN-EL 18a Battery, first is it possible without damage to the D500? Secondly, are there any advantages?

Works fine together and it gives you many more shots per charge. I have a generic DSTE EN-EL 18a that was like $40 on amazon. Has a built in charger which is pretty handy. I get about 1600 shots per charge on the regular battery and can get about 4500 with the en-el18a. The only disadvantage with the generic is that it doesn't show how much battery life is left as the camera thinks it AA batteries..
