Buying a second battery

[Fabdad]

Would anybody be able to tell if the 4 holes that hold the plastic outer guard on a BT-E8036 630wh battery are in the same place as the BT-E8035L 504wh battery. Toying with the idea of another battery so I can get another hour or so of riding and the 504 battery is a fair bit cheaper than the 630 one. Cheers
