Hi all,
I want a relay to turn on automatically when a sla battery gets 13.5v and turn off the same relay when the battery voltage drops below 13 or 12.5v. I am attaching the circuit which i tried and confused. Because this circuit turn on the relay but it never turn off the relay when battery voltage is below 13 , i don't know why. Any help would be appreciated. I have a couple of UA 741 op-amps to try with this circuit.
Regards
