The amp hours allow you to measure car battery amps through the practical lens of how long it will last between charges.

So if a battery has a rating of 100ah 20hr rate then that battery was discharged over 20 hours with a 5 amp load. Or 2 amps for 24 hours. In fact a battery of this type.

For example a battery with a 100 Ah capacity can deliver approximately one amp for 100 hours or two amps for 50 hours or four amps for 25 hours and so on. The 50Ah means that it can push 12 volts out at a rate of 50 amperes in an hour. An average car battery has a capacity of around 48 amp hours which means that fully charged it delivers 1 amp for 48 hours 2 amps for 24 hours 8 amps for 6 hours and so on.
