ELT batteries must be replaced by the date printed on the battery and after cumulative use exceeding one hour, or after any ELT activation. FAA regulations (14 CFR 91.207) require the replacement date to be legibly marked on the outside of the transmitter. Most lithium ELT batteries have a service life of 6 years, while rechargeable nickel cadmium packs depend on capacity test results and manufacturer intervals.
