7.2 Battery Service
No rechargeable batteries are installed in Emerging Lifesaving Technologies ELT.
Emerging Lifesaving Technologies 406 ELT batteries have a life limit. That limit (or
replacement date) is marked on the outside of the battery pack and a sticker is supplied for the
aircraft records. The type, make, model of ELT, the battery chemistry, and the expiration date
are indicated on the battery pack.
The internal battery clock will indicate during self-test if a minimum of 36 hours of normal
operations is still available.
Only Emerging Lifesaving Technologies approved batteries with the appropriate stickers can be
used in Emerging Lifesaving Technologies ELTs. See section 4.4.1 for battery replacement and
section 6.1 for self test.
