Because a battery gives off hydrogen gas when it is charging and discharging. Be careful not to create sparks around a battery especially when jumpering because hydrogen is volitile.
Have the charging system checked. The light comes on when there is a charging system problem. it may be a battery, alternator or a battery problem.
battery will make a gurgling sound when being charged while being charged, the acid(liquid) in battery heats up. u should not hear this in normal conditions in a vehicle should only hear it when on a battery charger check that sides of battery are not bulging.this is a sign that the battery is about worn out and is over charging, have battery, alternator and coplete charging system checked. batteries give off a gas when charging if overcharging, this gas is highly explosive and any small spark can ignite it
No.
Dead battery, Alternator not charging, Ignition off draw draining battery,.............
It is a good thing to disconnect the negative battery cable when charging, so no damage can occur to the car's computers.
The alternator switches off
There should be a little light next to the off button. Its green when the battery if fully charged, its orange when its charging/ needs charging and its red when its got very low battery. I hope this helps you :D
