Under normal use, it is very unlikely that a 1.5v dry cell will explode.
However, trying to charge a non-rechargeable battery, can make it explode.
The charging current causes gas to form in the electrolyte, which puts pressure on the case, which is usually non-vented. The increased pressure can cause the case to explode.
There have been chargers made, that will increase the life of single use cells, by charging them. These have a very small charging current, with long charge time, that does not allow gasses to build up.
Trying to fast charge a rechargeable battery will also make it explode, for the same reasons.
It is best to use only the charger specified for use with the type of battery. The charge currents (and even temperature monitoring) are built into intelligent chargers, to give the optimum charge without fear of explosion.
No, it will not explode.
Yes, it very well may explode.
If you reverse the battery cables, yes the battery can possibly explode.
Yes it could over heat and explode. Don't do it.
They will not explode. They can however burst.
15v appliances
The battery will explode.
If you explode you die and the same applies to a car battery.
Yes, a car battery can explode if jumped improperly. Car batteries contain sulfuric acid that can produce gasses. If a spark ignites the gases the battery can explode like a bomb.
, No. I did it powering a 15V peavey audio mixer using a lead acid 12V battery. But depending of your audio mixer, you may have levels problems. Emmanuel
It can explode.
Yes
