I was out about a month and, when returned, the battery of a MacBook (white) went most probably into a "deep discharge" state.
Battery shows 0% (not x) and doesn't charge when plugged in.

Are there any *tricks* I can try to recover a deeply-discharged battery?

Thanks! Reset the SMC, but still the same.
Only voltage keeps lowering...

Voltage (mV): 4846

iStat Pro also shows 0% health


It's a late 2007 MacBook, with a Battery with about 2 years. Just 10 cycles because it has been almost always plugged in. And during the late year not really much usage.

That's likely what helped kill it, as Apple doesn't recommend leaving it plugged in all the time. Read the AC POWER section of the Battery FAQ. In fact, reading it all would be helpful. You need a new battery.
