You can create a template sensor that reads the battery state and sets its own state to your value:

sensor:
  - name: "My Battery Health"
    unique_id: 13fe52a0-15a1-4d5b-956c-00114943d642
    state: >-
      {% set batt = float(states('sensor.my_battery_percent'), 0) %}
      {% set level = "Full" %}

      {% if batt >= 80 and batt < 100 %}
        {% set level = "High" %}
      {% elif batt >= 70 %}
        {% set level = "Medium" %}
      {% elif batt >= 60 %}
        {% set level = "Low" %}
      {% elif batt < 50 %}
        {% set level = "Very Low" %}
      {% endif %}

      {{ level }}

That’s somewhat random without knowing what your percentage to value table is but it gives you a starting place.
