Went out this morning and the damned car wouldnt start.. I kept trying and dragged the battery down to 12.2V and it would do anything... I cycled to the local motor place and bought a plug in charger, but this got me thinking.
But how about this.. If I'd chosen to be MacGyver this morning,
- take the SMPS out of my PC
- plug it in to the wall.
- jump pin 14 to ground to turn it on
- pull out a 12v DC + and GND - connection (one of the HD/CDROM connections) and hook it up to the battery..
- check the charge periodically with my voltmeter.
Would this not charge the battery with a smaller current, the same as the 8 amp charger that I bought, but obviously more slowly?
