In traditional "lead-acid" batteries, the electrodes are lead and lead (IV) oxide. During discharge, both electrodes dissolve in the strong acid electrolyte to form dissolved lead (II) cations. During recharge, these reactions are reversed. Other battery types, with a longer rechargeable life are used for hybrid electric-gasoline cars.

What safety precautions should I take when installing batteries - like the kind that are in cars that have around 12V- and an electric motor to my go kart?

A voltage of 12 V - as used in car batteries - is not particularly dangerous. You can even touch the electrodes, though I suggest not to touch BOTH electrodes at once.

How can lemon batteries be used to generate electricity?

Lemon batteries can generate electricity by using the acid in the lemon as an electrolyte and the metal in the electrodes as conductors. When the electrodes are inserted into the lemon, a chemical reaction occurs that creates a flow of electrons, generating a small amount of electricity. Multiple lemon batteries can be connected in series to increase the voltage and power output.
