I'll check the stock amperage for you tomorrow.
I'll get back to you on that.

 

Optima Yellow is primarily designed for sound. The Red Top is an ultimate car starter battatey. This may be the issue with the longet startup times. I have also noticed that when I installed the Yellow in other cars.

 

Sasha, I checked it today. I called our battery supplier and they told me the standard battery is a 70 ampere one. The number is 57024, but I don't know if they use the same numbers over there a they do over here.
The number must be on the battery.
So your optima has to be a 70 amp. or better.
Hope this helps
