Should your power be interrupted, the base unit of the medical alert system has a maintenance-free, built-in back-up battery that will operate your system for up to 12 to 20 hours. Before your battery runs out of current, the base unit will send a “low battery” signal to the ADT Health monitoring center to warn that the unit will soon be nonfunctional. An ADT Monitoring Specialist will then call you to advise you of the low-battery condition and answer any questions about your system.
Health & Medical Alert FAQs

The unit does not need regular servicing, but we recommend testing it monthly.
