well a car battery only has 12 volts but that doesn't explain why it shocks you

If you have been under the hood an received a shock it may have been from the high voltage generated by the ignition coil. 12vdc with the car not running should not normally be perceptible when touched.

If you can feel a shock from touching the contacts on a car battery, you either have wet skin or are unusually sensitive to voltage. A car battery, when cranking an engine, can put out over a hundred amperes, but there is no way that it could put anywhere near that much current through you.

The amperage of a battery depends on many factors. Load resistance, ambient temperature, level of charge etc.
You are probably asking about amp-hours or how much charge a battery will hold.
Read the label.
P.S. 12 Volts usually does not shock.

Really depends on the car and the number of cylinders the engine has - assuming it's not an electric car. 400-750 CCA
(or Cold Cranking Amps)
I've never been shocked by a car battery.

Zero. Amps are what you plug your speakers into.
Seriously though, it's a matter of cause and effect.
Voltage is the cause and Amps is the effect.
It's like you have a car and you ask how fast can it be pushed. Well, you can have 1 person push it and get one speed or you can have 10 people push it and get another speed.
ps you don't get killed by a battery unless you have wires coming off with needles on each which are stuck in your chest through which the current passes through your heart.
pps the reason you unplug your battery before working on you electrical stuff is because there are other things in the car such as coils, etc.

Amps is current flow, volts is like pressure. Car batteries are rated in amp-hours, which is an energy unit.
Why do you think that it shouldn't shock you? The critical thing here is that your body is providing a low resistance path for current to flow.

My Jeep battery gives up to 875 cranking amps. Ouch.
