How to restore a completely dead car battery (the easy way)

I do this often, especially if my vehicles sit for too long and the battery dies. The secret is to get the battery to 12 volts for even a few seconds, so that the charger will recognize it and start charging (for modern "smart" chargers.) I use my jump pack, but any type of jump will work. Once the car runs for a few minutes, as long as the alternator is also good, there should be 12 volts for a short time. The charger I use is a $40 "Fully Automatic Microprocessor-Controlled Battery Charger/Maintainer" from Harbor Freight. If I don't get the battery to at least 10 volts, it will not attempt to fully charge the battery. All the "smart" chargers I've used have done this, but I found out that getting it to 12 volts by jumping and running easily tricks the charger into reconditioning the dead battery.
