I order one of these batteries from AC every two years. Expiration dates are always current and they simply work as designed.

Used online service. Worked great. Quick delivery. Reasonable price.

Exactly what I needed. Paid too much for shipping. (My fault) should have looked closer to the shipping options. Take a good look at the shipping options before you complete your order other than that everything was great !!

It is an ELT battery doing ELT battery things. They don’t fail during the operational life. The exceptional part of the experience is how quickly Aircraft Spruce handles the order, shipment and over all customer experience. These good folks have the whole process down to a science. They’ve defiantly earned my future business.

Great price for a necessary item. The old ones last 8 to 10 years on the bench for testing.

The battery is fine. I ordered it and several other supplies in mid-May for my upcoming June 2019 annual inspection. This ELT battery has an expiration of May 2021. I would have preferred to receive a battery with a June 2021 expiration. I can appreciate selling older stock before newer stock, but if Aircraft Spruce was going to cut the margin this thin, I think they should have contacted me first and given me a chance to approve or reject.
