Watched Scotty Kilmer on YouTube and he speaks a lot of sense about Stop/Start. Says the ICE was not designed to be switched on and off, excess wear on components etc.
Wrong.
Some ICEs are designed to be switched on and off, so mr. Kilmer should not generalize: considering the quantity of hybrid vehicles running on our streets, we should see a massacre of engines due to the amount of switchings on/off, on the contrary hybrid ICEs appear to be the most reliable engines we have.
About the 1.5 sport battery, it's the same of the standard 1.3GK so sadly the list is very short.

The battery must be EFB since it has to bear higher recharge currents and more charge/discharge cycles.
So do not use standard (and cheaper) batteries, and do not use AGM batteries since the battery bay under the engine bonnet is not almost fresh to keep the AGM in low working temperatures.
