car Battery question.
Hi I have a question that I hope some one would be able to help me with.
I want to attach an item to my car that with draw 100amp. My car battery is 70ah and my alternator is rated at 70 amp.
I understand that a 70 ah batter will provide around 50amp for 1 hour or 100amp for say 30 minutes.
My question is. Because the alternator is in parallel with the battery will the available current double?
Also the battery will provide around 12.5v were as the alternator will provide up to 14v. Will this make a difference?
If I had the engine running when I draw the 100amp where will it come from?
I.e. 50amp from the battery and 50 amp from the alternator or 100 amp form the alternator.
i hope some one can help.
thanks
