Even at 8A, the battery will be flat after half an hour. And be aware that lead-acid batteries don''t like being left flat. Once run down, they should be recharged as soon as possible, or they may be permanently damaged. *1C is a current numerically equal to the amp-hour rating of a battery. So for an 8Ah battery, 1C is 8A.

How much voltage/current is "dangerous"?
How much voltage is dangerous is not really a static number as it depends on your body resistance, time of exposure and source "stiffness" (i.e. how much current it can supply). You get figures like 60V (or as low as 30V) which are an attempt at an average figure above which "caution should be taken".
