How is a car battery rated?
Volts, amp hours an cold cranking amps.
Can i use a home charger that has 3to 12V300mA output to charge my car battery at home?
No. The charger for a car battery has an output measured in amps. You have an output measured in milliamps. There are 1000 milliamps to 1 amp. Way too small.
How many volts does a battery need to start a engine?
a battery should be reading 12 or 13 volts at full charge you would need it over 10 volts but its hypothetical as it depends on the engine size10 To add it's not the voltage that turns the starter motor it is the amount of what is called cranking amps or cold cranking amps cca which refers to the amount of amps when 32 degrees Fahrenheit or up. If you have below the specific amount of amps for your starter it will click, turn but very sold, or do nothing. A 12 volt battery typically needs 400+ amps to start the car. While 5 volts means your battery is dead having 12 volts does not mean your car will start.
How many amps do you need to charge a car battery?

Can 36 volts of car battery power a 1hp electric motor?
Depends on the ratings(volts, amps, etc.) Definitely not an AC motor.
How many watts are in car bartteryes?
varies, go out and check on top of battery, should have sticker that says cold cranking amps. all batteries should run 12.6 volts, do the math from that.watts = volts * amps , take the CCA (cold Cranking amps) number on the Battery and multiply it by 12.6No one answer, as there is no one car battery. Most are 12 volt batteries, but that can really be anywhere from about 13.2 to 11 volts. A standard large battery will have ABOUT 50 amps of current. Multiplying volts times amps equals watts. 12 x50= 600 watts. HOWEVER- you cannot draw that much power for more than a few seconds. Heat buildup would damage battery.
How many watts is equal to 4.3 amps at 230 volts?
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
What setting do you set your charger on to charge a car battery?
I would recommend a slow charge of 10 amps at 12 volts.
Does your car battery have 12 volts 6 amps?
12 V - probably, although ther are exceptions. 6 Amps - ?? 6 Ams would be a measure of a current draw, and a battery is a current source. A car battery might have a capacity of 60 amp hours or thereabouts.
What current is a car battery?
It is 12 volts. The amount of current it can provide at 0 degrees F for 30 seconds is listed on the battery as Cold Cranking Amps (CCA). It varies from battery to battery.
How many amps does a car battery have when fully charged?
It varies by manufacturer and battery.
Cars use how many volts of electricity?
