Optima batteries are not failure mode proof because they are sealed or any other configuration referred to as not needing water added. They are good, don't take it wrong but they do have a failure mode due to age.
Internal resistance will build up as a function of time.
A reading of the battery will indicate fully charged, but when a heavy load such as trying to start the car is placed on them, the voltage at the terminals will drop well below the expected minimum of 8 volts used as a diagnostic for a good battery. When that happens ignition systems have a tendency to not work and the car won't start. It will crank fairly well but there is not enough voltage to run an electronic ignition. And unless you are measuring battery voltage at the time the cranking takes place, the battery will look as if there is not problem.
This type of battery is used in many mobility scooters simply because it does not out gas as a medical concern and that is the typical failure mode. But in a mobility scooter, as a prime source for power it is placed in a high current environment normally. I have only seen it a couple of times in automobiles as it only checks bad while trying to start the car.

Does anyone still sell the repro covers? I have a brand new battery, thought this would be a nice touch. I don't see them on AMARKs site...

Nobody sells them new anymore. I'm thinking it was the licensing issue?

Battery toppers are no longer available as stated above.....you basically have two choices here. Buy a basic black battery and add the battery top stickers sold by APD or Kennedy American maybe other vendors also.  Or buy a reproduction battery which probably wouldn't be any more correct than the stickers because I don't think they repop  a 74 style  battery.
