Is there a device which determines how many volts remain in a
connected 12v battery and automatically disconnects at a preset
voltage and reconnects at another preset voltage. The presets being
variable and determined by the user.
If so could you tell me what its called please.
I would be grateful for advice,
regards

Technically what you need is a device called a 'comparator' linked to a
relay or similar )possibly solid-state mosfet).

Let me guess, to charge a battery from a PV panel ? Are you using a
'maximum power point' controller ? If not then DO !
