Do NOT carry batteries in your pocketsThere is only one explanation for a battery getting hot when carried in someone's pocket.

That cause is that something metallic [coins, keys, or something similar] in the pocket contacted the battery's two terminals, created a short circuit, and thus a very heavy drain on the battery. That heavy current drain rate caused the battery to heat up.

This is a very dangerous practice, and many times has been documented to have caused extremely severe and painful BURNS to people who have ignorantly carried batteries in their pockets. It it also has been documented that such shorted batteries can and have exploded causing severe and painful injuries.

Do NOT carry batteries in your pocked, BUT... IF you are going to do so, cover both terminals with a plastic terminal cap [like comes with new 9 volt batteries], or securely cover the terminals with electrician's tape.

A 9 volt battery can get hot in your pocket due to a short circuit caused by the metal objects like keys or coins touching both terminals of the battery simultaneously. This leads to a rapid discharge of energy and generates heat. It's important to store batteries properly to avoid such incidents.

What is stronger 1.5 volt batter or a 9 volt battery?

A 9 volt battery is stronger than a 1.5 volt battery because it has a higher voltage. The higher voltage allows the 9 volt battery to power more demanding devices and last longer than a 1.5 volt battery.


What happens to the current in a circuit if a 1.5 volt battery is removed and is replaced by a 9 volt battery?

If a 1.5 volt battery is replaced by a 9 volt battery in a circuit, the current flowing through the circuit will likely increase. This is because the higher voltage of the 9 volt battery will provide more electromotive force, pushing more current through the circuit, assuming the resistance remains the same.


What is maximum current of 9 volt dc battry?

The maximum current capacity of a 9-volt DC battery will depend on the specific type and size of the battery. However, for a typical alkaline 9-volt battery, the maximum current output can range from around 500mA to 1000mA. It is important to check the specifications provided by the manufacturer for the exact current rating of the specific battery model.


Can you use a 9.6 volt DC drill battery to extend the life of a standard 9 volt DC electronic item?

Using a 9.6 volt DC drill battery with a standard 9 volt DC electronic item may damage the electronic item due to the higher voltage. It is better to use a voltage regulator to step down the voltage to 9 volts before connecting it to the electronic item to avoid any potential damage.


Does a 9 volt battery light a light bulb?

Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
