I run tested used Yellow tops in both of my Jeeps and they will sit for a month at a time or longer and have started without a hiccup every time I turn the key even in the winter. Some folks "kill" their Optima prematurely due to having a weak alternator that can't keep up with recharging them, then they bring the battery in thinking it's dead when it just needs to be PROPERLY charged, and the same people will slowly kill(discharge) a new battery and start the cycle over again. These Optimas end up getting a proper charge and load tested before they are sold again at great savings, these are what I am running and love them.
This makes zero sense. Yellow Tops as with any deep cycle batt have a high internal resistance which makes them harder to charge and therefore not the best choice as a starter battery. To say that these batteries get damaged due to low charge rate would be counter to what a deep cycle is supposed to withstand and therefore makes the batteries as asstastic as I've stated for years.
Since vehicle charging systems have been controlled by ECMs in vehicles since the 90s and they gain little benefit from a larger alternator, it would seem that Optima batteries are simply not compatible with newer vehicles.
