Ah = Ampere Hour - the total number of amps over a 20 hour period the battery can discharge before going below 10.5V. So if you have a Ah rating of 75: 75/20 = 3.75A for 20 Hours

The rest are explained here:

So if you wanted to find out how much power you could drain for like 10 hours, since you diveded by 2, you times the amperage by 2, so for 10 hours it would be 7.5 amps?

And thanks for the info.
