They have to be pressure canned.
I do a quick soak, put beans in a pot after they are cleaned and boil for 2 minutes.
Cover and let set for one hour.
I put onions and jalapeños in my jars with 1/4 tsp salt and 1/4 tsp pinto bean seasoning.
Fill jars 3/4 full with beans, then pour boiling water over them, need to get air out of jars with a plastic knife going down the sides of the jars shaking them a little.
Put lids on and pressure can, there’s instructions all over the place on how to pressure can.
Pts-75 minutes
