Dave,
All the literature I have seen for rating the amp-hour capacity of lead-acid batteries use a 20 hour discharge rate. So, in your case, that would be about 5 amps. Obviously, if you draw more than 5 amps, you will not get the rated capacity.

FWIW - I've been using a Sears Marine part #27582 lead acid battery as a power source at the field. Weight is about 65 pounds. Rated capacity is 108 amps (can't remember what discharge rate was used to yield that capacity).
