Reverse-Current Circuitry Protection | Analog Devices
The simplest protection against reversed-battery current is a series (a) or shunt (b) diode. As an improved battery-reversal measure, you can add a pnp transistor as a high-side switch between the battery and the load (Figure 2a).
Is a Schottky diode appropriate for reverse polarity protection?
Reverse leakage current is simply the deviation away from the ideal case in which there would be zero current flow. Having reverse leakage means it will eat some of your battery power. At 100 mA it will be unnoticeable, but it is the offstate leakage that you care about.
