This one crept up on me. I ordered an ACK E04 ELT from Aircraft Spruce 12/2018 and installed it 02/2019. The battery expired 02/2021. I contacted ACK and asked them how long these units sit prior to shipment as I understand they are a 5 year battery at a minimum. They said they ship them out within 1 week of manufacture, which means it sat on the shelf at Aircraft Spruce nearly 3 years before shipping out to me. I asked ACS if they would pro rate a new battery and I'm waiting on their reply. I'm writing this to remind anyone to double check the expiration date and insist ACS send you one that has near full life still left rather then a fraction thereof. Hopefully ACS will step up on this one. I should have paid closer attention, however.
