Integration to add battery notes to a device, with automatic discovery via a growing battery library for devices.
Track the battery type, when the battery was replaced, when a battery is low based on device or global thresholds and also when a device hasn't reported a battery for a while.

A battery+ sensor provides useful attributes for easy use in dashboards, the standard battery can optionally be hidden.

Battery low, replaced and not reported are all via events and services, you have the option of creating your own automations for these or using the predefined ones in community.

A lot of the inspiration for this integration came from the excellent PowerCalc by bramstroker, without adapting code from PowerCalc I'd never have worked out how to add additional sensors to a device.

Huge thanks to @bmos for creating the issue form & automations for adding new devices.

Thanks to everyone who has submitted devices to the library.
