What happens if a battery bank's absorb time is set too low?  Or too high?

    Too low, and the battery never fully charges and begins to sulfate and loose capacity.

    Too long, AGM :  will vent/gas and looses electrolyte that cannot be replaces
    too long flooded :  will heat up a bit, maybe flake off plate material, but generally only needs a bit extra water.
