Yeah, when mentioning lithium I was referring to the batteries in your 500w unit. If you can access the battery pack connection internally you may be able to charge them back to life directly with a "dumb" charger (one that tries to charge regardless of the current state of your batteries).
For your AGM batteries (and lead-acid in general) you need to get them up to their rated boost voltage most days or they will become weaker. Generators usually don't put out enough DC to do this, and if you have it running an AC charger, you have to ensure your AC charger is peaking at high enough a voltage. Sometimes that's setting it even higher than the batteries recommend, to account for cable losses and increased resistance as the batteries get older. It sounds like you have some nice gear and it should be settable, but even for cheaper chargers (like mine!) there are usually adjustment screws on the inside.
