The equation V/R=A (where V=voltage-volts, R=Resistance-ohms, and A=Amperes-amp) can be used to figure the amps at a certain voltage and resistance.
If You short circuit a 9 volt battery (cross the two terminals) with a paperclip, then the voltage will be 9 volts and the resistance will be in the range of .1 ohms.

∙ 14y agoI assume that you are referring to a 6 volt lantern battery.
That depends on the battery.
Typical values are between 7500 and 11000 milliamp hours (about one amp for one hour).
Discharge rates tend to be around 250 milliamps (a quarter of an amp).
Putting these together, you can draw about a quarter of an amp for about four hours from a typical battery.
I have not affiliation with this site but it is where I got my answers from and they sell the batteries that they post the specs for:

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.
9 volt power supply in place of a 10 volt?
Probably ok if the new supply can produce the required amount of current in amps.
How many watts in a 9 volt battery?
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 happens to the current in a circuit if a 1.5 volt battery is removed and is replaced by a 9 volt battery?
Current will go up by a factor of 6 times in that scenario.
How many 9 watt bulbs can an 14 amperes 12 volt battery support?
Batteries are normally specified in ampere hours. A 12 v battery could be specified as 14 A-h or 14 ampere-hours, which means 14 amps for 1 hour, or 1.4 amps for 10 hours. In other words it produces less current for a longer time. A 9 watt bulb takes ¾ amp in theory, so it should last 14/¾ hours on that battery, that is 14 x 4 / 3 hours, 18 hours. Or two of the same bulbs for 9 hours, etc.
How many amps are in a 9volt battery?
It varies from one 9 volt battery model to another. The typical Alkaline 9 volt battery you find in many toys and smoke detectors has 565 mAh (Milliampere Hours) of power. A Zinc Carbon model has 400 mAh. A Lithium has 1200 mAh. There are 1,000 mili amps in 1 amp.
How much power is generated when a 9 volt battery produces a current of 5 amps?
45 Watts
Is 9 amp drill as powerful as 14 volt?
Your question is similar to: "Is an apple more powerful than an orange?" You are comparing two different parameters. Electric Power = Volts multiplied by Amperes = Volt-Amps. To know which drill is more powerful, you need to compare the Volt-Amps of each drill with the other one. If the battery voltage is the same for both drills (it probably is not), then the one with the highest motor current rating SHOULD be the most powerful. However, manufacturers tend to fudge some on their ratings. When they say "This is a 9 Amp drill", often it is not clear or not defined what they mean. Is the battery rated for a 9 Amp output, or is the motor rated to use 9 Amps maximum, or 9 Amps average, or are the wires running from the battery to the motor rated for 9 Amps? You see what I mean. Electric power cannot be measured in Amps or in Volts, but must be a combination of the two (Volt-Amps, or Watts, or Horsepower, or some known and well-defined power quantity).
What is stronger a 1 amp battery charger or a 9v battery?
You cannot compare these two totally different things. As far as amperage the charger puts out more amps if it is an auto battery charger and also puts out 12 volts. If you are talking about a 9 volt battery charger then the battery may or may not be more powerful, it depends on how many mii-amps the charger is putting out.
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
Two resistors are connected in series to a 9 volt battery. The larger resistor provides twice as many ohms resistance as the smaller one. The current through the circuit is 3 amps. What is the resista?
