Hi One very practical option: Pull the battery and don’t replace it. When the unit next comes out of storage, run it on a very normal UPS. The battery was a fine idea back in the era when this gear was newly designed. These days, the better option is an external “bulk” backup.
If you are going to run 24/7/365, the charger circuit in all of these gizmos (HP liked battery backup …..) is not the best for long term battery survival. It’s not awful, but it’s not what you would do today. If the unit goes into storage most of the time, batteries really don’t like that very much either.
