Q: 10. It looks like the same form factor as my 1D mark iii, mark iv, and X batteries. Will my existing batteries still work?

A: (cross posting). The batteries are interchangeable. The LP-E4 and LP-E19 have the same form factor and contacts. The LP-E4 will work in the 1DX Mark II at reduced camera performance. You can use the LP-E19 backward to the 1D Mark III but to get full battery performance you need the new charger. Otherwise the old charger will only charge to the performance level of the LP-E4 that it was designed for. Read about it by searching for canon lp-e19 charging with old charger that will go to the Canon learning article.
