Please explain why.
Automotive alternators are not designed to charge and maintain that type of battery. RV and Boat alternators are.
For this reason, even my local Autozone (significant in the fact that they usually don't give a crap) are refusing warranty claims on alternators if a yellow top is installed in the vehicle.
I recently bought a new red top for the Zilla, and while in the store, one of the 'clerks' was trying to sell me a yellow instead. The manager chewed his
surprisingly. I'm personally very pleased some stores are now realizing what it'* costing them.
If you run a yellow or deep-cycle, run it as a second battery behind an isolator. For your primary battery, choose a conventional automotive battery or a red-top.
