Too much heat going into batteries, batteries are damaged, or batteries manufactured wrongly
Hooking the battery cables up incorrectly. Reversing the polarity can cause the battery to explode.
By fully charging and fully discharging some batteries the expected charge time can be increased. Some rechargable batteries will last longer per charge if they are fully discharged before you recharge them again. Recharging batteries before they are fully discharged may cause a battery memory effect that will allow the battery to run for a shorter period between recharges.
Cause you wanna.

Batteries aren't in properly. Battery contact points dirty. New batteries are faulty.
The Sun is _not_ exploding, now or ever; our Sun isn't massive enough to become any kind of nova star.However, the Sun will begin to expand into a red giant star in about 4 billion years,
I dont know the answer
Depends on where you get the electricity to recharge the batteries. If the electricity is produced in a hydro-electric plant then there is almost no pollution. If the electricity comes from a nuclear power plant then you have nuclear waste. If the electricity comes from a coal-fired plant that you do have pollution from the burning of coal.
batteries in a car is bigger and cause exploions and flash light dont they bring light to the flashligt

Hard to say. It may cause no damage at all and then again it might cause serious problems.
