Revive Stone Dead Battery?

[Mr Nick]

I have an optima red top battery, apparently the Cutlass has a parasitic drain I need to track down. Battery is at 2.2 volts. My cheapo charger will not recognize it at that level, and displays "fault." Charger works fine on other batteries.

I was thinking of hooking it up in parallel with another good battery and charging it like that, so the charges 'sees' enough voltage to work, but that sounds like a "It seemed like a good idea at the time " type of thing...


Is there a way to revive this battery, or is it toast?
