Reviews

My AK-451 batteries were due for replacement. Rumor had it that replacement cells were not available. Our chapter tech counselor suggested checking the Aircraft Spruce on line catalog. Sure enough, there they were. I ordered a set and they appeared to be identical to the originals right down to the manufacturer. I checked their voltages which were identical to the originals, 3V. Keep in mind that while they are D size, they are not your hardware store D cells which are 1.5V. I installed them in my AK-451 which tested perfectly. Time will tell how they will hold up, but hopefully I will never need to use them for real! Im happy with my purchase.

Last installation of these batteries only lasted 3 years. No operations of my ELT in that time. hope this next set lasts longer

It would be nice if the battery pack came with a sticker to apply over the old sticker on the ELT with the new battery replacement date.

Q&A

Q: I have a 5 year old AK-451 in my home build plane. Purchased from Aircraft Spruce. How many batteries do I need to replace the existing batteries in it? I believe the U10029

The AK-451 takes 4 batteries, so to replace them all, we recommend ordering the 4 battery kit.

Q: Does this battery fit and is legal in an Ameriking ELT AK-451 for a certified aircraft?

This battery is not FAA TSO approved. It will fit the Ameriking ELT. Please check with your A&P or local aviation authority for eligibility of legal installation.

Q: Are these batteries hazmat for shipping internationally?

Yes, these are considered hazardous for air shipping.
