I need to charge my car battery. It's very dead at this point. But, I have a variable voltage power supply that's rated for 5A.
I've had it hooked up to the battery at about 15V (if measured without anything hooked up to the power supply) And I've found that around 130mA flows in this configuration. From my measurements, I'm getting about 11-12V.
I've charged the car for 3+ hours, but it hasn't worked.
Should I turn up the voltage? How long do you think this would take? I welcome any other advice you all have as I'm attempting to be both engineer and car repairman here.
