Sudden Major Vehicle Battery Failure

When you get a real DieHard Battery experience, know you are not alone.  Internet has many similar type vehicle battery failures.  I have had both car and motorcycle battery do this. With Sudden Major Vehicle  Battery Failure,  the battery shows full 12.8 volts when you hit start switch, you still see 12.8 volts, and relays do not close when you press start.  You expect starter failure on ignition switch circuit problems and call for a tow.  Even attempts at jump starting cause faint  headlight glow or none at all.  One person said his lights came on alright but nothing happened.  You may have used the vehicle several times that day with no problem. Circuit shows charged vehicle battery with large resistance to make headlight do faint glow.  Best way I know to show symptom you see as resistance seems to be inside of battery. Even if a jumper battery or charger is added to vehicle battery. I call this the Old Starting Load Test as with new battery failures it has not been working.  1) Adjust voltmeter to DC 20 volt range. 2) Connect voltmeter to battery + to + and - to - 3) With ignition switch ON, watch voltmeter as you try to start engine. 4 If battery voltage goes below 9.5 volts, the battery capacity is very low and battery should be replaced. Replacing with a new battery completely clears up the problem caused by Sudden Major Vehicle  Battery Failure. Yesterday, I talked to man with 13 years experience in vehicle battery company and no scientific reason for why this occurs has been given to him.  Just different battery solves the problem.  After work one day, he drives to gas station for gas and car does this to him.  Jump start attempts did not work on his car so he knows what it feels like as it happened to him like it does to his customers.

The battery man mentioned problem seems temperature related. A few days close to same temperature then up or down change of temperature is likely failure time.
