I have an old car and battery with the Negative dis connected, I
charge it, 2 days later it shows 70% charge of 12v or so, is it a
junk battery, I think so. Only the Positive is connect but the case
is clean


So? What is your question?

He asked if the battery is viable or junk?

I've no idea what the answer is, but I think I'd clip a headlight to it
to drain it down until the light dimmed, then recharge again and see
what it looked like. And, ask how he's measuring the charge remaining.
