A car battery has six cells each producing two volts. A 9v alkaline battery has six cells each producing 1.5 volts. There are some obvious differences, like that a car battery can put out hundreds of amps and a 9v alkaline can only put out hundreds of milliamps, a 9v battery weighs 45 grams versus 45 pounds for a car battery, and so on.
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.
A battery can have Ampere hours, but how many amps it will deliver is influenced by what the battery is hooked up to.
Current, I is equal to V (voltage) divided by R (resistance); Hence: I=V/R = 9V/200 ohms: I = 0.045 Amps, or 45ma (milliamps).
60 Millie amps
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
9v! More voltage, more strength! Many 9v batteries merely have 1.5Volt cells jammed together to make 9V!
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).
To charge a car battery you need aproximatly 8000 amps To charge a car battery you need aproximatly 8000 amps
1.5 Amperes, or Amps.
In Digital multimeter we use 9V Dc battery.
To determine how many amps a battery can handle, this information should be on the battery itself. You can also get a battery tester to determine amperage.
It depends on the size of the battery. |Amps is usually measured on a car battery in cca (cold cranking amps) The higher the number the more power the battery has, or stamina, the longer it will last.
Depends on how you measure it. A 9V battery is nine volts, while a AA is 1.5 volts, but they probably have approximately the same total power.
you better not. you need a 9V regulator for this, not a resistor!
Depends on the battery. They are not all the same. It depends on the battery , a BCI group size 65 battery is rated at 650 cold cranking amps
modern cars use a 12 volt battery. Amps depends on the battery. Common sizes range from 500-800 cold cranking amps.
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
It varies by manufacturer and battery.
