The question should be how many amp-hours in a battery. In a small batt. like a 9V, this is measured in milli-amp hours (mAh), with 0.5 amp hours equaling 500 mAh. This means the battery could power a 0.5 amp load for 1 hour. Data I have seen shows the best alkaline 9V being between .3 and .5 amp-hour (300 to 500 mAh).

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.
Does a 9 volt battery have more energy than a 1.5 volt battery?
A D cell battery has a voltage output of 1.5 volts, while a 9 volt battery produces about 9 volts. This is just the potential energy though. D cells provide far more current for a longer time then a 9 volt battery. In terms of overall power output, a D cell in give you many times more power than a 9 volt battery. Physical size, in this case is a good indicator as the material inside is the same.
Can you use a 9.6 volt DC drill battery to extend the life of a standard 9 volt DC electronic item?
no, a 9 volt battery is small (goes in a smoke detector) a 9.6 volt battery is much larger, and it is not a DC battery (direct current) but NiCd (nickel cadmium.) two totally different things.
How much power is generated when a 9 volt battery produces a current of 5 amps?
45 Watts
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.
Can you use a 3 volt charger for a 9 volt battery?
No
Can you use a 6 volt charger for a 9 volt battery?
No, the battery will be overcharged and battery damage will occur if it is done.
Is a lead acid car battery the same as a 9 volt alkaline battery?
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
What Happens if a 9 volt battery touches another 9 volt battery?
It heats up very hot and may explode.
Can a 9 volt charger be used to charge a 7.2 volt battery?
no
How fat is a 9 volt battery?
1.3cm

a 9 volt battery
How do you reboot a rechargeable 9 Volt battery?
buy a battery charger
What does a battery clip do?
it operates a battery,mostly a 9 volt battery
What is the difference between a 9 volt battery riding car and a 12 volt battery car?
One is 9 volts and the other is 12 volts. They do not interchange!
