Kannad ELT battery replacement

What’s the best source for ELT replacement batteries for Kannad? They last 5 years and 5 years ago Germany mandated the 406 MHz update so the ELT makers are cashing in loads of money again.

Trying to find the least expensive source for a Kannad 406 AF-C.

I use a french dealer at … LFAT !

Charged me 300€ for the last one, including full test procedure.

I saw quotes for 600€ in Deutschland …

Can they test a foreign reg ELT (bought in the USA)?

Surely you can just swap over the battery?

I think I can install it myself and the transponder is tested as part of the annual avionics check.

406s are different animal than what we were used to with the 121s …

Good luck finding someone to sell you the battery out-right.

A proper test requires the proper test equipment.

What are you referring to as “proper test equipment”? I was under the impression that the yearly ELT test that is done as part of the avionics check would be sufficient. They turn on the ELT and listen on 121.5MHz (radio) and check when the battery was changed. The avionics guy wants me to take care of the battery.

@Jesse, how do you handle Kannad 406 battery changes?

I vaguely recall that a 406+121.5 ELT (which is all the European ones, nowadays) may be tested only during the first five minutes of each hour.

During that time, the satellites disregard the signals.

But how do you KNOW it’s functioning properly ?

Look it up under the “Continued Airworthiness” section of your ELTs owners manual.

I saved you the trouble :

1. Maintenance Schedule
A. Periodic inspection
Note: (if required by the relevant Civil Aviation Authority).
Some Civil Aviation Authorities may require the ELT is tested periodically. In
this case, KANNAD recommends to check the following parameters:
• G-Switch activation.
• Battery voltage.
• 121.5 MHz / 243.0 MHz / 406.025 MHz transmission power.
• 121.5 MHz / 243.0 MHz / 406.025 MHz frequency.
• 121.5 MHz AM (sweep monitoring with VHF receiver).
• Number of 406 MHz transmissions (optional, programming kit required).
• Number of self-tests carried out (optional, programming kit required).
• Programmed data (optional, programming kit required).
NOTE: This functioning check can be carried out without opening the
ELT.
These tests are described in Service Letter “SL S18XX502-25-12”.
B. Every 6 years
Testing of the various elements of the ELT is mandatory every 6 years together
with the battery replacement.
• Visual control of the housing and accessories
Refer to CMM 25-63-01or CMM 25-63-05.
• O-ring, battery and desiccant capsule replacement
Refer to CMM 25-63-01 or CMM 25-63-05.
• Beacon Tightness
CMM 25-63-01 or CMM 25-63-05.
• “Testing and Fault Isolation” procedure as described in CMM 25-63-01.
NOTE:
• CMM 25-63-01: level 3 CMM, reserved for KANNAD service stations only.
• CMM 25-63-05: level 2 CMM, available upon request or on KANNAD
Website.
