12v Battery Auto Cut OFF Auto ON Circuit With TL431 YouTube
This is a simple Li-ion battery charger circuit with an automatic cut-off when fully charged. This circuit will help revive batteries that you think are dead or so old that they can no longer be reused. We made the circuit with commonly used components such as the NE555 timer and TL431 shunt regulator.

Low Battery Voltage Cutoff or Disconnect
We will use this circuit and the cutoff voltage is equal to 2.5V multiplied by 1 plus the ratio between the two resistors of the voltage divider. For example, with 2k and 1K, the cutoff voltage would be 7.5V. When the input is below that voltage, the TL431 will power off the transistor gate so the load is not powered.

Deeply discharging a starting battery is about the worst thing you can do, short of keeping it there for an extended period. That's the type of unknowns you get when you buy a blem-- but personally, if the price was right I'd definitely roll the dice. For $45 I'd try it once, if it works out, every time.

Use a momentary push-button and a 12V relay such that the TL431 holds the relay pulled in while the battery is discharging. Put the relay coil and TL431 on the load side of the relay contact, so no current is drawn after the battery the voltage sags below the cutoff point.
