I received 2 dutyone 20v 3600 mah li-on batteries with an adapter & charger on 4/19/2021 a b&d hedge trimmer now what?that no longer charge fully.

Don't know. I have one charger and two batteries for an extension-pole hedge trimmer that have not missed a beat for years. R U sure the charger is charging? Might take a voltage meter and figure out whether your problem is charger or batteries. With two batteries going bad at the ~ same time I would suspect the charger is bad.

Is this compatible with a Maxlander leaf blower?

The Maxlander battery must be compatible with the Black and Decker 20V battery, which I don't think it is.
