Dead battery?

This should be done when it happens? Or can I do it anytime? This is a random event which nobody can duplicate and may not happen again for a day, or a week or if I am very lucky a couple of weeks. Depends on how cold it gets. Never happens during the summer.

It needs to be done when the problem occurs. That is when you will be able to identify if it is an electrical issue or fuel related.

Our car was running fine this am, drove it about 25 miles, parked. Went to leave, battery was dead. We jumped the battery off, and it cranked, but the dash lights blink, and the battery is not charging at all. We drove the 25 miles home, turned off car, wouldn't crank again.

Also, measure the voltage across the battery terminals. It should read around 12.6 volts with the engine not running, and must be between 13.75 and 14.75 volts when the engine is running. If less than 12 volts with the engine off, there's a shorted cell in the battery. If the voltage stays the same after the engine is started, the charging system is not working. There are some easy fixes, but you will need to troubleshoot the system first.
