I need a diode for dual DC power input circuit basically battery backup. Every barrier, blocking, rectifier diode I can find on Amazon rated for 10 amps or greater all say for solar panels. Can I use these diodes on my circuit? The circular will pull no more than 10 amps at 12 volts.

Okay. I figured as much. Just second-guess myself because literally every rectifier, blocking, schottky diode I could find listed on Amazon rated over 10 amps all said for solar panels in the title. I just received them in the mail yesterday. I'll let you know how it works out

Thanks again

The best way is to use mosfets to create an ideal diode.

google for ideal diodes or fet as diode.
advantage V_forward <12mV @ 50 Amps ( this is an example look at datasheets).
