Starter draw is typically under 100amps. The battery has to be in good enough shape to take the 150 amp (fuel injection, pump, and ignition) draw plus not allow a voltage drop below 10 volts. Coils don't really fire well at lower voltages if at all.

usually around 600 amps, but it depends on the engine you have. For example, a larger engine will require more amps than a smaller engine. a typical 5.0 L V8 requires about 650 amps, and some SUVs have larger and smaller engines. So check your engine,and get the right battery.

150 Ltr.........

There isn't one set answer for this. It'll have to do with the displacement of the engine, the output of the starter required to get it to crank at enough speed to start, etc. Huge difference between, say, a 4.6 liter Land Rover V8 and a 12.0 liter Detroit Diesel 8V92 diesel V8.

7 pocket amps

That depends on several factors: If the car battery is FULLY discharged, a starter can pull as much as 200 AMPS when you try to start the engine, depending on the size of the engine. If the car battery is only "low", but still carries a pretty good charge, you might be able to get by with considerably less than 200 AMPS.

Almost any auto battery will start the engine if it is runnging good. But I would buy at least a 500cca battery.

Power equals voltage times current in amps. The value of amps used is needed to do the math.

amps equals watts divided by volts.

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.

A 15 amp circut will be fine.

It depends on the alternator.A diesel produces more amps because of the 24 volt system.14 amps on a 305....
