Audio-Technica LI-240 Lithium-Ion Battery

The LI-240 is the rechargeable lithium-ion battery used to power the Audio-Technica ATUC-IRDU infrared discussion unit, the portable delegate station in the ATUC-50 wireless conference and interpretation system. Meeting rooms that run all-day sessions keep spares charging so a discussion unit never goes dark mid-session.

It is sized specifically for the IRDU rather than a generic cell, so it drops straight into the unit's battery bay and reports charge state through the ATUC-50 system the way the rest of the conferencing hardware does.
