ACK E-04 ELT Batteries

[JWE]

We have an ACK E-04 ELT in our aircraft, and we need to replace the batteries. There are evidently 3 batteries in the system. The main lithium battery, [FONT=&quot]one in the RCPI (Remote Control Panel Indicator)and one in the audio alert indicator.[/FONT] I have looked through the literature that came with the ELT, and I find the part number for the main battery but can't seem to find part numbers for the other two. I want to order the batteries to have them ready for my IA as we are about to do the annual. Anyone able to provide the part numbers?

Thanks in advance.

The smaller batteries don't have a expiration date on them it is on the package they come in. Make sure they note when the small batteries will expire in the logs so you don't have to replace them every time you replace the main one.
