Also keep in mind guys that EMP wont damage a car battery at all - zip - or the alternator - what it will fry is the electronic ignitions and computers that run the emission system - but if you have a car built pre-1978 EMP will basically do nothing to it at all - i.e. that old 1966 Impala you have will run just fine and start up just fine - and so would the old fashioned 8 Track player or cassette player thats in it or the old fashioned car radio - not today's heavily electronic radios - so if you are looking for a traveling "boom box" for a game look for an older car
FYI for those looking for EMP effects on automobiles and trucks interesting discussion that includes a study on cars and trucks made from 1986 thru 2002 that said that if the cars and trucks were turned off there was NO effect on them from EMP. They had to be on at the time for their to be any damage at all and in the case of trucks even then the damage was minimal.
