2AHr ones supplied but two of them, I wonder what the battery life

like and how does the 1.7J impact energy compare?

I have an old Bosch 12V SDS which is capable of drilling 3 or 4 10mm
holes to about 3" deep on a charge - when the battery is in good
condition, of course.

What capacity batteries? They'd need to be 4AHr to store the same
energy as 2AHr 24V ones.
