Shipped quickly, fit perfectly. Easy install. Came with change date. I made my own sticker for the ELT but that was easy. Good for almost 5 more years.

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.
