Nope. The list of things an owner/operator is allowed to do is very
specific. Replacing, testing, or logging the replacement or testing of
an ELT battery is not on the list. (Appendix A to Part 43 -- Major
Alterations, Major Repairs, and Preventive Maintenance).

I know that I am allowed to replace the ELT battery of my airplane. At the
same time, I performed an ELT check as stated in FAR 91.207. Not being an
A&P or an IA, am I allowed to perform this check and sign off on it?

Thanks in advance for any responses,
