Interesting point! I think the original intent there was lead-acid
starter batteries, but it does indeed just say "batteries".
And I should correct my statement to say that while the owner/operator
can replace the battery (hell, he can replace the entire engine), he
can't make the logbook entry for return to service.

According to a Wings seminar I once attended, not only is allowed to log what
he/she did, the owner is *required* to log it.
