what does battery Ah mean?

Looking at lead acid batteries the voltage and Ah is generally described on the battery itself, for example the Yuasa NP7-12 is described as 12V 7Ah. In this instance the 7Ah is given as the 20 hour rate, this tells us that at a constant discharge over 20 hours the battery will produce 0.35 amp per hour (20 hours x 0.35 = 7Ah).
