Is it possible to reverse a car battery connection?
During the life of the vehicle, its battery may need to be disconnected for maintenance work or to replace it if it has developed a fault. During reconnection it is possible to reverse the polarity of the battery connection, which can result in potential short-circuits and other problems with loads connected to the battery.
Can a reverse battery be connected to an ECU?
Inserting a MOSFET in the high-side supply to the ECU and connecting the gate so that the device is turned on only when the battery polarity is correct is an alternative solution. Since the MOSFET on resistance (RDS (ON)) is typically only a few milliohms, I2R power losses are low compared to the loss incurred due to the diode VF.
Is it possible to reverse the polarity of battery connection?
During reconnection it is possible to reverse the polarity of the battery connection, which can result in potential short-circuits and other problems with loads connected to the battery.
Can a lead acid battery be reverse charged?
With a lead-acid battery it will reverse charge, but you may compromise the battery life and efficiency. I know the two poles are different materials (lead anode and a lead-oxide cathode).

Can a store hook up a car battery backwards?
The store should pay to restore your car to the condition is was in before they messed up the battery installation. The position of the old battery is not material, and is no excuse for the store hooking up the + cable to the – terminal of the battery. They owe you to make it right, it was their mistake.
