It's possible. Not likely to be the battery itself it that happens, though.
Yes
No. The battery will be charged at a rate which is 2* the normal rate. This will cause the battery to overheat which might cause it to explode.
Any kind of spark can cause a fire in the presence of an accelerator like gas fumes. It can happen even with a 1.5 volt battery.
It is not recommended to charge a 6 volt battery with a 12 volt battery charger as it can damage the battery. The higher voltage can overcharge the battery and cause it to overheat. It is important to use the correct charger with the matching voltage to prevent damage to the battery.
fresh battery will be about 14000 volt to 20000 volt but very little amp
Absolutely not! It is a 14 volt drill. Use a 16 or 18 volt battery will destroy the drill in short order. It will run but not for long.
No
if it is any think over 1 volt it is not a cell battery it is just a 6 volt battery if you had a 1 volt then it would be a cell battery
No, you cannot charge a twelve-volt battery with a forty-eight-volt charger, as the voltage from the charger far exceeds the battery's capacity. This can cause damage to the battery, lead to overheating, or even create a safety hazard. It's important to use a charger that matches the voltage specifications of the battery to ensure safe and effective charging.
No, it will overcharge the 6 volt battery.
No
The battery is a 12 volt.
