Let''s say that this is a battery with 7Ahr capacity and that you want to draw 14A. You''ll have to observe the 2C curve (2C means to discharge at 7Ahr*2/h=14A). You''ll note that this battery will drop to 9.5V-10V after about 15mins. Of-course this is only true for a fresh from the shelf battery kept at 25 deg.Celsius.
