Would the Aichi D3A or Mitsubishi A6M Zero have an external or internal electrical battery to start its engine?

12v 20A lead acid battery

The battery in my motorcycle was bigger than that

You are not going to get very many tries on starting with such a small battery.

There may have been an external plug. Depending on conditions (temperature? number of aircraft to be launched? time of flight on last flight to charge battery? ) the crew may have cranked, or used a battery cart (if available) or used the internal battery.

Going by the info from the post about the Hamp. I think this might have driven an electric motor that in turn drove an inertia starter, but I'm guessing. I've seen no power carts on Japanese Carriers

leaving the electric motor out of the inertial starter can certainly save weight. But that means it is hand crank all the time. You can't use the internal battery.

If you have the electric motor attached to the inertial starter then adding a few feet of wire and plug/connector for an external battery doesn't seem like big a deal.

My thoughts as well

This Forum is amazing. Anyone have the part number of the flower vase for a 1910 R.E.O. Speed Wagon?

And with that, it's now time for a musical interlude:

My mechanic had this old cartoon on the wall of his shop. One mechanic on the phone asks the other mechanic "we got a flower vase for a 1910 R. E. O. ?"
I knew the Forum would know the answer.

VFSW9100-339. I thought everyone knew that.

That was for the RED vase, what about the SKY BLUE colored one?

Would the Aichi D3A or Mitsubishi A6M Zero have an external or internal electrical battery to start its engine?
