That would be my assumption too.  However, for the load test, I'd try
to put enough load on the batteries to discharge them in 20 - 30 hours
(the AH spec is based on a 20 hour discharge.)  That would require
drawing about 30 amps.

I suspect that the load test mentioned by JSpence tests the ability to
deliver a high current, as for starting, and won't determine the AH
capacity.
