Guide Can a Car Battery Kill You?
However, it''s not the voltage alone that poses a threat; it''s the current (amperage) that can be harmful. A car battery can produce a high current, which, if passed through the body, can lead to serious injuries or even be fatal in extreme cases. The most common scenario where electrical hazards occur is during improper jump-starting or handling

Guide Is charging with an underpowered charger harmful to the overall battery
The battery is charged by Li-ions filling the gaps between molecules of the electrodes, and current by definition is a measure of the rate of flowing charge, negative electrons in this case. So the current is analogous to the people trying to get through the limited number of doors and the open seats are the interstitial (space between molecules) gaps.

Guide The Effect of Electric Current on Human Body
The principle that ”current kills” is essentially correct. It is the electric current that burns tissue, freezes muscles, and fibrillates hearts. However, electric current doesn''t just occur on its own: there must be voltage available to motivate electrons to flow through a victim. A person''s body also presents resistance to the current
Guide Why is a 12V household battery virtually harmless, but a 12V
The voltage of a battery is the voltage it can put out under no load- think of it as a max. However, once that battery is putting out some current, the battery itself has something called "internal resistance" which goes up the higher the load (or current draw). So really, the above equation has to be re-written V = I/(R_body + R_battery). And

6 Frequently Asked Questions about “Is low current harmful to the battery ”
What happens if you don't charge a battery?
If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell. As a result, the voltage in the cell rises – this is known as over-charging. On the one hand, this is harmful to the battery and bad for its life span. On the other hand, it can pose a safety risk for the user.
Can You charge a battery with less current?
You can always charge a battery with less current. Heck you can even not charge it (no current). But if the battery wants to charge with more current than the adapter can handle, the adapter might overload. If it's a good adapter it will just switch off. If it's a crappy one it might catch fire. So your choice.
What if I charge a battery with low ampere?
Electrical Engineering Stack Exchange What if i charge a battery with low ampere.? Assuming we have a mobile-phone LiIon battery and a charger which is only able to supply less ampere than the original one, will it damage the battery if i charge with less ampere charger than the original one.
What happens when a battery is 100% charged?
After battery is 100% charged, it reaches a voltage level that it is not able to store energy. Then, the current injected into the LA battery is used to electrolyze the water in the solution, generating hydrogen and oxygen gases - known as gassing, and depleting the electrolyte level.
What happens if the current is too low?
If the current is too low, it will result in the formation of fewer but larger crystals in the perspective of total discharge, which in the case of incomplete charging will result in, as in the previous cases, a loss of active material and a reduction in the battery capacity.
What happens when a battery is fully charged?
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
