Oh, I misread, it was potentially 5 years without advertising...
My usage when actually connecting to the puck would be to connect, transfer about 572 bytes of data, then disconnect... I definitely don't need high-bandwidth mode so that's good to know.
I suppose I could also increase the advertising interval and lower the BLE transmit power since it'll only need to function within a foot or two of the device that's writing to it and it doesn't need to be detected immediately since the application itself will be scanning in the background for it.
I don't have a target for the battery life, but I also don't want it to go flat prematurely if I can do simple things to prevent it.
