It certainly is. I think you'd probably be surprised if you opened
most ELT batteries. They are commonly just a bunch of off the shelf
alkaline batteries that are soldered together inside a box. You'd
never know it from the price tag :-))

The trick is the "legality" issue. It's the certification by the
company that solders all those other batteries together that makes it
legal. For decades there was no traceability on commercial batteries
bought at your local 7-11 store. Duracell started to "brand" their
batteries with expiration dates traceable back to the manufacture date.
THAT made them legal to use, and allowed ELT manufacturers to start
making units that used them.

Anyone with such a unit, can you verify that you can't legally just
plunk in *any* D-Cells, but rather that it has to be specific brands
(i.e. Duracell), or has to have the date listed on/with the battery?

I don't have the unit yet but when I talked to ACK, the manufacturer of the
E-01 ELT that is powered by D batteries, the representative kept specifically
using the phrase, "Duracell D batteries" every time he mentioned the issue of
the unit taking batteries. I thought it a bit odd that he continually
referenced the battery by brand name, but not enough to ask him why.

My ameri-king uses only duracells and they have to be replaced every
year.

That's not true. According to ACK's document
http://www.ackavionics.com/images/Mo...ELT_Manual.pdf
You only need to replace the Duracell dated batteries before the
expiration date printed on the batteries. That document is an FAA
approved document.

The Ameri-King manual is he http://www.ameri-king.com/pdf/9.1.22.pdf,
says pretty much the same thing about batteries.

You're right they only strongly recomend changing the batteries every
year. It may be a Canadian requirement though that made me think I
have to. It's not really an issue cuz I recycle the used batteries
into flashlights.

The hell you say. They have to be replaced by the code date on the battery.

My Ameriking AK-450 uses D Duracells and specifically says they are
for the duration marked on the batteries, close to five years for
the set I put in last.

I've seen the doc for two brands (IIRC, ACK and Ameri-King) and
both specifically directed the user to use dated Duracells.

I have the ACK unit with the D cell batteries. It requires the duracell batteries with a date code, not just
the ordinary flashlight batteries. They are good for 4 years.
