Default Wow.....

....that was exhausting. But lots of information and opinions. So, I'm in the market to replace my Ameriking 451 which is draining my batteries, (remote and main unit) because according to the FAA, Ameriking isn't even allowed to work on units needing repair.....even though they will still invite you to send in your malfunctioning unit.

What units are currently available which use Ultralife D [b]sized[b] batteries which can be accessed should I decide to replace them myself? Another requirement is that the remote fit the panel cutout in which the Ameriking remote was mounted.

None of the new 406Mhz ELTs use simple to replace D size batteries because they have more powerful transmitters that require more battery power.

The only option you have is to buy an 121.5 Mhz ACK ELT from from someone wanting to upgrade. The panel mounted control panel is pretty much teh same size as the ameriking.

Default D Size Batteries

My Ameriking 451 (121.5 / 243 / 406) uses Ultralife D [b]sized[b]batteries which are 3v as opposed to the common D-cell battery's 1.5v. There are four of them which are "field replaceable".

I'm looking for a new unit which uses the same batteries, whether as a "pack" or inserted individually, which are accessible for field replacement, whether intended to be so or not. I have a strong physical reaction to paying $200 for $50 worth of stuff.

How can there be 8 pages of back/forth about ME 406 ELT Battery?

Just buy a new battery when you're supposed to and get on with life.

This is like following the Kardashians...

I guess I'll throw in the towel. I got this answer from AOPA:

Thanks for reaching out to us in the Pilot Information Center.

91.207 applies to all aircraft. EXCEPT as mentioned in the paragraph you highlight...(a)(1). It calls out the exemptions in Paragraphs (e) and (f), Experimentals are not listed.

That being said, (e) only refers to Ferry operations. And (f) lists 10 exemptions to the us of an "approved" ELT. TSO'ed or Certified equipment are all that will be acceptable.

Please feel free to reach out to us with any other questions you may have.
