Using the excellent Battery State Card by maxwroc you can easily display devices with their batteries required where the devices battery threshold indicates it's low and show be replaced.

This requires creating a helper of type text called Battery search with a max length of 20, which you can then reference in the below yaml on a dashboard.
type: vertical-stack
cards:
- type: entities
entities:
- entity: input_text.battery_search
name: Search by battery type
icon: mdi:magnify
secondary_info: none
state_color: false
- type: markdown
content: |-
{% set search_term = states('input_text.battery_search') | upper %}
{% if search_term != "" %}
{% set devices = states | selectattr('attributes.battery_type', 'defined')
| selectattr('entity_id', 'search', '_battery_type$') | list %}
{% set matching_devices = devices | selectattr('attributes.battery_type', 'string')
| selectattr('attributes.battery_type', 'eq', search_term)
| map(attribute='name') | unique | list %}
{% if matching_devices | length > 0 %}
{{ matching_devices | join('\n') }}
{% else %}
No devices with such battery type
{% endif %}
{% else %}

Raise a persistent notification when a battery is low, dismiss when it's not low
!!! note
Battery Threshold events are only raised when the device has a Battery+ entity or a [Battery Low Template](./index.md/#battery-low-template) is added to the Battery Notes configuration.
