Two main reasons:
- voltage - batteries usually(but not always) have such a low voltage that
they can't push a dangerous current through a human body.
- muscle interaction - Batteries are DC (direct current) while mains are AC
(alternating current). And AC current will cause the muscles to spasm and
lock, so if you were to accidentally grasp something electric, it'll be really
hard to break free.
But don't get this wrong. If you know what you're doing, it's entirely possible
to kill yourself with nothing but a 12-volt battery.

Why is the shock from a household outlet more dangerous to you if your skin is wet?
You conduct electricity better if you are wet.
Is some electricity more efficient than others?
Since electricity is energy, it has only one type. Therefore, some electricity cannot be more efficient than others because all electricity is the same. However, some devices use that same electricity more efficiently than others.
What is the difference between electricity mains current and the current from a battery?
Answer for countries in Europe and other world areas running a 50 Hz supply service.grid current (the electricity mains) is *AC (alternating Current, The voltage follows a sinus curve going from (here in Europe) 240 V to -240 V and back fifty times second.The current from a battery (like from my car battery (actually a lead acid accumulator) is DC mine is 12 V. There are batteries in many sizes for many different uses.I can pull more amperage from my car battery (during a few seconds) than I can from my wall socket!
Is a thunderstorm more dangerous than a hurricane?
No. In most cases a hurricane is far more dangerous.
Why is a battery more useful than main electricity?
Since battery power involves electricity, I guess the question should be "Is battery powered more efficient than mains (or grid) powered?". Battery as well as grid, is a way of transporting electric energy. So the question is which is more efficient. At first glance it is easy to say that transportation via grid can be as high as 99,9% efficient when the distance is no more than 100 m, and can be as low as 88% when the distance is at the range of 1000 km. The efficiency of the transportation of the electric power via battery is maximum at the range of 90% (since there is always at least 10% of the power left in the battery).
What is difference between battery and mains electricity?
Mains supply provides alternative current while battery provides direct current.
Why is 240 volt electricity more dangerous than 12 volt electricity?
It is neither more or less dangerous . The determining danger factor is amperage.
Is cyanide dangerous working around electricity?
Cyanide is dangerous, period. Electricity is dangerous, period. Nothing about the one makes the other more dangerous. Still, either one is dangerous enough by itself that I would not recommend working with both at the same time.
Why is an outlet more dangerous than static electricity?
an outlet has a higher volts than an ordinary static electricity
What electricity ranges are dangerous to humans?
According to Wikipedia, the electricity ranges that are dangerous to humans are those more than 30 mA (60 Hz). Shocks that strong can seriously damage your tissues.
Which is more powerful a torch bulb or a mains filament bulb?
Mains filament
Why is the shock from a household outlet more dangerous to you if your skin is wet?
You conduct electricity better if you are wet.
Which is more powerful a torch bulb or a mains filament lamp?
Mains filament
How dangerous is electricity?
About as dangerous as a kitchen knife. Both are very useful, but in inexperienced hands, or used carelessly, can kill you or someone else. Bottom line - If you are going to work around electricity, get the proper training! If you are using electric appliances, read, understand, and follow the instructions.
Are electrical generators dangerous?
All electricity can be dangerous. The higher the voltage and current capacity of the generator, the more dangerous it can be. Besides the danger of electrocution you hav eto make sure you don't get anything caught in a rotating part or perhaps burnt by a hot surface.
What is the difference between mains electricity and battery operated electricity?
Batteries range in output voltage from 1.2 volts for an AA rechargeable, to 12 volts for a car battery. There may be other voltages, for special purpose applications. Batteries supply DC (direct current), meaning that the current will only flow in one direction.What is considered "mains" electricity (from a plug or receptacle in the wall) is alternating current (the current is oscillating between flowing one direction, then the opposite direction then back and repeats). It oscillates at 50 or 60 times per second, depending on what country you live in. Also the voltage is between 100 volts and 250 volts, depending on the country, as well. These features enable the voltage to be changed up or down rather easily with transformer, and allow the electricity to be transmitted over long distances.But the alternating current and higher voltages also make your mains electricity much more dangerous to touch than a battery. A person's skin has pretty good resistance to electric flow, especially direct current. But with alternating current, if you touch a wire, charges can actually form under the skin and start flowing through your body, because your skin acts as a capacitor. Then, the oscillating current back and forth through your organs is much more damaging, possibly causing your heart to stop pumping.
What is the comparative and superlative to the word dangerous?
