Schottky diodes are appropriate for battery plate applications when rated for sufficient amperage and low voltage drop
A minimum amperage rating around 10 amps or higher is recommended for battery plate diodes
Low voltage drop is a key selection criterion to minimize power loss in the circuit
Schottky diodes may show a small reverse voltage reading when tested with a meter, which is a characteristic tradeoff for achieving low forward voltage drop
A small reverse leakage current in Schottky diodes is insufficient to cause batteries to charge each other, despite the meter reading

The diode should be positioned on the hot lead
The examples given are specific models chosen for overspecified ratings and low voltage drop rather than as universal recommendations
No detailed testing or quantitative loss measurements were provided
