USED TO.... as the battery deteriorated, the engine would crank slower or even studder and you had warning of impending failures..
TODAY.. the computer monitors the battey voltage while cranking, and if it drops below 9volts cranking, it just refuses to even let the car try to crank... no slow cranking, no studder, just a click and no crank as the computer will not allow it to happen as it cannot set timing or idle or anything else with low voltage, so its program to not even try if the voltage drops.
SO.. bottom line,, newer cars will experience the sudden 'NOTHING" symptoms by design.
Yes there is still shorting cells or open cell failures vs the sulfation of the plates.. but now.. who can tell.. it just does NOT crank.... only a test of the battery after its pulled out will tell you what happened, but who cares, if a new battery fixed the problem, you just move on.
