Keep in mind that, although you cant be electrocuted by simply touching the terminals of a regular car battery, due to the low voltage, you can receive a nasty shock from other components of a traditional automotive electrical system.
What happens if you touch battery cables together?
Whenever you touch the battery cables together and drain the capacitors the clock will lose its memory, the radio stations will need to be reset, all fault codes will be cleared, the outside temperature may take some time to relearn, any systems with security codes will need to be reset and the computer will need to

Can you connect two battery cables together?
Note that if your cables are too short to connect the two batteries, you can connect two sets of jumper cables to give yourself more length. Put both cars in park (or in a gear for a manual) and turn them off. Attach the other clip from the same cable to the positive terminal on the good battery.
Which battery terminal do I connect first?
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
What happens if you disconnect the positive terminal first?
Its important to disconnect the negative side of the battery first, otherwise you can cause an electrical short if the positive is removed first.
Can you touch exploded batteries?
The potassium hydroxide that leaks from batteries is a corrosive material that is highly toxic. The caustic material can cause skin irritation and damage your eyes. It can also cause respiratory problems. Avoid contact with your skin.
What happens if you drop a car battery in water?
nothing, nothing happens to a car battery when it gets wet, mostly. A lead-acid battery as a mixture of sulphuric acid and water inside the casing. There are some plates inside, that do something (very scientific, I know.) Anyway, the water inside dilutes the acid and the effectiveness of the battery is weakened.
What to do if a battery explodes?
The best way to remove alkaline leakage from the device is to neutralize by carefully dabbing with a few drops of a mild acid like white vinegar or lemon juice. For stubborn leaks, an old toothbrush dipped in vinegar or lemon juice gets the job done.

What is the correct order to connect jumper cables?
Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that wont start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.
How many 12 volt batteries can you run in parallel?
two batteries You will get 12 volts and 1200 CCA if you have two batteries in parallel. If you have 2x the current reserve you can operate your electronics for 2x as long as you dont have to charge the batteries.
Do I hook up the negative or positive first?
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
